# Sports Sedans with More Power than a Ferrari F40

There are three kinds of Chargers in this list.

It's not too long ago that these horsepower figures were once reserved for supercars and exclusive grand tourers. The Dodge Charger not only dominates the super-sedan crowd, but uses three trims to exceed the horsepower rating of the classic Ferrari F40 supercar.

## No disrespect to the Ferrari F40

Ferrari's F40 is worth more than a million dollars today and is basically well known for having changed the supercar world; its main competition initially included the Porsche 959 and Ruf CTR, but it later grouped with likes of the Bugatti EB110 and Jaguar XJ220. It can do 0-60mph in 3.6sec (100km/h in 4.1s) and the quarter-mile sprint in 11.9sec, as well as reach a top speed of 201mph (324km/h)!

The Ferrari F40 was a champion in its time with the highest power rating (471 bhp) of any street-legal production car.

Please keep in mind that this list is limited to sports sedans (hence the title) and the occasional luxury full-size sedan; we will avoid the ultra-luxury cars like the Bentley Flying Spur and Rolls-Royce Ghost. This list also only includes purely gasoline-powered sedans (and the occasional "mild hybrid"); this means obviously no plug-in hybrid cars or electric ones. Below are the ones either currently in production or about to begin production.

## Mercedes-AMG C 63 â€” 469-503 bhp (479-516 lb-ft)

Image Credit: Mercedes-AMG

We get it, the standard Mercedes-AMG C 63 is not technically "more powerful" than the Ferrari F40. However, its extra torque (479 lb-ft versus the Ferrari's 426) makes up for the very slight lack of power (469 bhp versus the Ferrari's 471 - a very marginal gap). The gap in torque is much bigger than the gap in horsepower. The S version makes 503 bhp and 516 lb-ft of torque. Both versions are available only with rear-wheel drive and a nine-speed multi-clutch transmission.

With an estimated quarter-mile time of 12.1sec (or 11.8sec with a one-foot rollout) at 120mph (192-194km/h), the standard C63 may reach 0-30mph in 2.2sec (50km/h in 2.3s), 0-60mph in 4.0sec (100km/h in 4.1s), and 0-100mph in 9.1sec (160km/h in 9.0s -- 200km/h in 12.8s).

With an estimated quarter-mile time of 11.9sec (or 11.6sec with a one-foot rollout) at 123mph (197-199km/h), the C63 S may reach 0-30mph in 1.7sec (50km/h in 1.8s), 0-60mph in 3.8sec (100km/h in 3.9s), and 0-100mph in 8.1sec (160km/h in 8.0s -- 200km/h in 12.1s).

Mercedes-AMG claims a top speed of 155mph/250kph for the standard C63 and 180mph/290kph for the C63 S.

## Lexus IS 500 F Sport Performance â€” 472 bhp (395 lb-ft)

Image Credit: Lexus

The Lexus IS 500 F Sport Performance is not a successor to the outgoing IS F. However, it does carry the 5.0-liter powerplant of the very powerful RC F. To maintain its sleeper status, it shares very little with the RC F. Instead it retains the IS 350 F Sport appearance while being stuffed in with the V8 motor. Despite its power rating, it is intended to rival likes of the BMW M340i and Mercedes-AMG C43, rather than the BMW M3 and AMG C63, so expect pricing to be around $60,000 in the United States.

With an estimated quarter-mile time of 12.8sec (or 12.5sec with a one-foot rollout) at 116mph (186-187km/h), the IS 500 F Sport Performance may reach 0-30mph in 1.8sec (50km/h in 1.9s), 0-60mph in 4.5sec (100km/h in 4.7s), and 0-100mph in 10.2sec (160km/h in 10.1s -- 200km/h in 14.2s).

Lexus does not claim a top speed yet, but the LS 500 (which also isn't a full-on F car) is claimed to reach 168mph/270kph (yes, electronically limited!) - same as the RC F and the outgoing GS F. The IS 500 F Sport Performance is available only with rear-wheel drive and an eight-speed automatic transmission, and it will be exclusive to the North American market.

## Cadillac CT4-V Blackwing â€” 472 bhp (445 lb-ft)

Image Credit: Cadillac

The Cadillac CT4-V Blackwing has been confirmed to use the same 3.6-liter twin-turbo mill as the outgoing ATS-V, but with a slightly improved horsepower rating of 472 bhp. It is positioned as an in-betweener sports sedan; while it is destined to compete with likes of the Audi RS3 and Mercedes-AMG CLA45, it is also capable of rivaling the Alfa Romeo Giulia Quadrifoglio, BMW M3, and Mercedes-AMG C63. Expect pricing to be around $60,000 in the United States.

With an estimated quarter-mile time of 12.3sec (or 12.0sec with a one-foot rollout) at 118mph (189-191km/h), the CT4-V Blackwing may reach 0-30mph in 1.8sec (50km/h in 1.8s), 0-60mph in 3.8sec (100km/h in 3.9s), and 0-100mph in 9.3sec (160km/h in 9.2s -- 200km/h in 13.0s).

Cadillac claims a top speed of 189mph/304kph, which is impressive considering the CT4-V Blackwing's 472-horsepower rating. It comes with rear-wheel drive, as well as a six-speed manual or a ten-speed automatic.

## BMW M3 â€” 473-503 bhp (406-479 lb-ft)

Image Credit: BMW

The legendary BMW M3 has joined the list with a whopping 480 metric horsepower (or 473 brake horsepower)! Not only that, but its Competition variant makes 510 PS (503 bhp)! It still uses a 3.0-liter twin-turbo inline-six, but the newest major mechanical addition is a paddle-shift eight-speed automatic transmission (as a replacement for the outgoing seven-speed dual-clutch). The Competition variant comes with a six-speed manual or a ten-speed automatic. Transmission availability for the standard M3 is complicated. It's only available in the United States with the automatic, and also only available in Germany with the manual.

With an estimated quarter-mile time of 12.4sec (or 12.1sec with a one-foot rollout) at 117mph (187-189km/h), the standard M3 may reach 0-30mph in 2.1sec (50km/h in 2.2s), 0-60mph in 4.1sec (100km/h in 4.2s), and 0-100mph in 8.8sec (160km/h in 8.7s -- 200km/h in 14.1s; automatic) â€“ 9.9sec (160km/h in 9.8s -- 200km/h in 13.5s; manual).

With an estimated quarter-mile time of 12.0sec (or 11.7sec with a one-foot rollout) at 123mph (197-199km/h), the M3 Competition may reach 0-30mph in 1.8sec (50km/h in 1.9s), 0-60mph in 3.8sec (100km/h in 3.9s), and 0-100mph in 8.1sec (160km/h in 8.0sec -- 200km/h in 12.2s).

BMW claims a top speed of 155mph/250kph (and 180mph/290kph with the M Driver's Package) for the all new M3 model (governed in both cases), regardless of whether it's the Competition trim or not. Expect the upcoming CS and GTS versions to exceed 190mph/305kph.

I was going to include the Alpina B3, but it is a bit of a weakling compared to the M3 at 456 bhp. It's not to say that the Alpina is weak as a whole (it's very powerful and it's backed by 516 lb-ft of torque!).

## Dodge Charger Scat Pack â€” 485 bhp (475 lb-ft)

Image Credit: Dodge

One of the last naturally aspirated pushrods in production, the 6.4-liter starts life as a 5.7-liter; but then the extra power kicks in! With 485 horsepower, the Dodge Charger Scat Pack is no Hellcat, but it's still an easy bang for the buck. It didn't have any direct competitors until Toyota released the semi-track-focused Avalon TRD, and even that car is stuck with a 3.5-liter V6.

With an estimated quarter-mile time of 12.4sec (or 12.1sec with a one-foot rollout) at 111-114mph (178-184km/h), the Charger Scat Pack may reach 0-30mph in 1.6sec (50km/h in 1.7s), 0-60mph in 4.3sec (100km/h in 4.5s), and 0-100mph in 9.5sec (160km/h in 9.4s -- 200km/h in 15.0-16.5s depending on variant).

The narrow-body Charger Scat Pack has a true top speed of 187mph/301kph (albeit electronically limited to 175mph/282kph). The Widebody variant is technically slower [at approximately 170mph/275kph] due to the added fenders. Rear-wheel drive and eight-speed automatic are a mandatory combo.

## Alfa Romeo Giulia V6 â€” 503-533 bhp (443 lb-ft)

Image Credit: Alfa Romeo

The Quadrifoglio Verde (QV) version is the beginning of the V6 range for the lightweight Alfa Romeo Giulia, and then the GTA and GTAm models run on top of them. It should be noted that Alfa Romeo uses two different brake horsepower figures for the Giulia QV; 503 for most markets and 505 for the North American market.

With an estimated quarter-mile time of 11.8sec (or 11.5sec with a one-foot rollout) at 124mph (199-200km/h), the Giulia QV may reach 0-30mph in 1.8sec (50km/h in 1.9s), 0-60mph in 3.8sec (100km/h in 3.9s), and 0-100mph in 8.1sec (160km/h in 8.0s -- 200km/h in 11.8s).

With an estimated quarter-mile time of 11.5sec (or 11.2sec with a one-foot rollout) at 129mph (207-208km/h), the Giulia GTA and GTAm may reach 0-30mph in 1.8sec (50km/h in 1.9s), 0-60mph in 3.7sec (100km/h in 3.8s), and 0-100mph in 7.3sec (160km/h in 7.2s -- 200km/h in 10.8s).

The Giulia QV can only be offered with rear-wheel drive and an eight-speed automatic, although a six-speed manual had been offered in the past. The GTA and GTAm will remain the same in powertrain except for the big power increase. The top speed is 191 mph for the QV.

## BMW M550i xDrive & Alpina B5 Bi-Turbo â€” 523-600 bhp (553-590 lb-ft)

Image Credit: BMW

Even though the BMW M550i xDrive is technically a competitor for the North American-spec Audi S6 as well as the Mercedes-AMG E53 hybrid, it is actually much closer to the RS6 (an Avant-only version) and E63 (non-S) in terms of straight line performance. The M550i's only real competitor is the Maserati Ghibli Trofeo, which is another calm, comfortable, V8 sleeper sedan (without quite going into supercar territory).

With an estimated quarter-mile time of 12.2sec (or 11.9sec with a one-foot rollout) at 120mph (192-194km/h), the M550i xDrive may reach 0-30mph in 1.9sec (50km/h in 2.0s), 0-60mph in 3.6sec (100km/h in 3.8s), and 0-100mph in 8.4sec (160km/h in 8.3s -- 200km/h in 13.1s).

With an estimated quarter-mile time of 11.6sec (or 11.3sec with a one-foot rollout) at 128mph (205-207km/h), the Alpina B5 may reach 0-30mph in 1.7sec (50km/h in 1.8s), 0-60mph in 3.3sec (100km/h in 3.5s), and 0-100mph in 7.2sec (160km/h in 7.1s -- 200km/h in 11.0s).

All M550i come with all-wheel drive and eight-speed automatics. Top speeds are restricted to 155mph/250kph for the M550i and its mechanical siblings. However, the Alpina B5 and B7 both top out at 205mph/330kph.

Other four-door models using this powerplant include the BMW 750i/Li and M850i Gran Coupe, as well as the Alpina B7 and the upcoming B8 Gran Coupe.

## Mercedes-AMG E 63 â€” 563-603 bhp (553-627 lb-ft)

Image Credit: Mercedes-AMG

Unlike the BMW M5, the E63 AMG is intended for extreme refinement while still delivering supercar-like performance. All-wheel drive and nine-speed multi-clutch are a mandatory combo. The E63 and E63S versions are also available in Estate variant.

With an estimated quarter-mile time of 11.9sec (or 11.6sec with a one-foot rollout) at 125mph (200-202km/h), the standard E63 may reach 0-30mph in 2.0sec (50km/h in 2.1s), 0-60mph in 3.4sec (100km/h in 3.5s), and 0-100mph in 7.4sec (160km/h in 7.3s -- 200km/h in 11.8s).

With an estimated quarter-mile time of 11.4sec (or 11.1sec with a one-foot rollout) at 130mph (208-210km/h), the E63 S may reach 0-30mph in 1.6sec (50km/h in 1.7s), 0-60mph in 3.2sec (100km/h in 3.4s), and 0-100mph in 6.8sec (160km/h in 6.7s -- 200km/h in 10.4s).

Mercedes-AMG claims a top speed of 155mph/250kph for both the E63 and the E63 S, but you can order either one to reach 186mph/300kph with the AMG Driver's Package.

## Audi S8 â€” 563 bhp (590 lb-ft)

Image Credit: Audi

The Audi S8 is now a mild hybrid, and it can be offered in standard- or extended-wheelbase formats. It's still all-wheel drive and it comes with an eight-speed automatic transmission. It's basically a poor man's Porsche Panamera Turbo, since many people may not want to pay extra for the Porsche badge in a similarly-sized and similarly-powered sedan.

With an estimated quarter-mile time of 12.3sec (or 12.0sec with a one-foot rollout) at 119mph (191-192km/h), the S8 may reach 0-30mph in 2.1sec (50km/h in 2.2s), 0-60mph in 3.6sec (100km/h in 3.8s), and 0-100mph in 8.7sec (160km/h in 8.6s -- 200km/h in 13.4s).

Top speed is restricted to 155mph (250km/h), although a "plus" model should arrive someday with a top speed of 189-190mph (305km/h).

## Maserati Ghibli Trofeo â€” 572-580 bhp (538 lb-ft)

Image Credit: Maserati

Maserati's Ghibli Trofeo is a very powerful beast and basically a four-door Ferrari Roma. Maserati quotes a top speed of 203mph (326km/h), which is actually 4mph faster than the Roma. The Ghibli Trofeo comes with rear-wheel drive and an eight-speed automatic transmission.

With an estimated quarter-mile time of 12.3sec (or 12.1sec with a one-foot rollout) at 122mph (196-197km/h), the Ghibli Trofeo may reach 0-30mph in 1.9sec (50km/h in 2.0s), 0-60mph in 4.1sec (100km/h in 4.3s), and 0-100mph in 8.7sec (160km/h in 8.6s -- 200km/h in 12.7s).

## Maserati Quattroporte Trofeo â€” 572-580 bhp (538 lb-ft)

Image Credit: Maserati

The Maserati Quattroporte Trofeo is the brand's first serious Quattroporte since the 1990s-era models. It's sort of a competitor for the full-size super-sedans, but it's also really an extended wheelbase variant of the Ghibli Trofeo; it also has a top speed of 203mph (326km/h).

With an estimated quarter-mile time of 12.4sec (or 12.1sec with a one-foot rollout) at 122mph (196-197km/h), the Ghibli Trofeo may reach 0-30mph in 1.7sec (50km/h in 1.8s), 0-60mph in 4.3sec (100km/h in 4.5s), and 0-100mph in 8.8sec (160km/h in 8.7s -- 200km/h in 12.8s).

## Mercedes-AMG GT 63 â€” 577-630 bhp (590-664 lb-ft)

Image Credit: Mercedes-AMG

Forget about the E63! The GT63 is the real M5 chaser - with the power and acceleration it needs to battle that car. One could argue that it's a competitor for the M8 Gran Coupe, but it's really more four-door liftback than four-door coupe. I would compare it to the Audi RS7, even though that's much cheaper than this one. It's also had a history of breaking the NÃ¼rburgring record for four-door executive sedans.

With an estimated quarter-mile time of 11.6sec (11.3sec with a one-foot rollout) at 125mph (200-202km/h), the standard GT63 may reach 0-30mph in 1.3sec (50km/h in 1.4s), 0-60mph in 3.2sec (100km/h in 3.4s), and 0-100mph in 7.5sec (160km/h in 7.4s -- 200km/h in 11.5s).

With an estimated quarter-mile time of 11.2sec (11.0sec with a one-foot rollout) at 128mph (205-207km/h), the GT63 S may reach 0-30mph in 1.2sec (50km/h in 1.3s), 0-60mph in 3.1sec (100km/h in 3.2s), and 0-100mph in 7.0sec (160km/h in 7.0s -- 200km/h in 10.6s).

Mercedes-AMG claims 193mph (310km/h) for the standard GT63 and 196mph (315km/h) for the GT63S.

## BMW M760Li xDrive â€” 577 bhp (627 lb-ft)

Image Credit: BMW

It's not too long ago that sleeper barges were of American tradition (see: 1990s Chevrolet Impala SS, 2000s Mercury Marauder). The BMW M760Li xDrive actually competes with the Audi S8 and the outgoing Mercedes-AMG S63, but without the flashiness or the sportiness. Its 6.6-liter mill makes it slightly bigger than the current Dodge Charger SRT Hellcat (6.2L), the future Cadillac CT5-V Blackwing (also 6.2L), and the defunct Mercedes-AMG S65 (6.0L). On a totally different subject, that kidney grille just keeps growing and growing! On a side note, the M760Li was actually discontinued at the end of last year; but why not include it anyway?

With an estimated quarter-mile time of 12.4sec (or 12.1sec with a one-foot rollout) at 120mph (192-194km/h), the M760Li may do 0-30mph in 1.5sec (50km/h in 1.6s), 0-60mph in 3.5sec (100km/h in 3.8s), and 0-100mph in 8.5sec (160km/h in 8.4s -- 200km/h in 13.3s).

BMW only claims one governed top speed; 190mph/305kph.

## Jaguar XE SV Project 8 â€” 592 bhp (516 lb-ft)

Image Credit: Jaguar

The Jaguar XE SV Project 8 is the Hellcat that Dodge never made. Featuring a supercharged mill displacing five liters, the track-focused four-door sedan broke the NÃ¼rburgring record for compact executive sedans. It has a governed top speed of 186mph/300kph in Touring form, as well as 200mph/322kph in (a still road-legal) track-focused trim.

With an estimated quarter-mile time of 11.7sec (or 11.4sec with a one-foot rollout) at 122mph (196-197km/h), the XE SV Project 8 may reach 0-30mph in 1.7sec (50km/h in 1.8s), 0-60mph in 3.3sec (100km/h in 3.7s), and 0-100mph in 8.0sec (160km/h in 8.0s -- 200km/h in 12.1s).

## BMW M5 & M8 Gran Coupe â€” 592-626 bhp (553 lb-ft)

(Images Credit: BMW)

The BMW M5 has different power ratings for different markets. The European market has the 592bhp base M, the 616bhp Competition model, and the 626bhp CS; while the North American market gets the 600bhp, 617bhp, and 627bhp versions respectively.

With an estimated quarter-mile time of 11.5sec (or 11.2sec with a one-foot rollout) at 129mph (208-210km/h), the standard M5 may do 0-30mph in 1.3sec (50km/h in 1.4s), 0-60mph in 3.0sec (100km/h in 3.4s), and 0-100mph in 6.7sec (160km/h in 6.6s -- 200km/h in 11.1s).

With an estimated quarter-mile time of 11.3sec (or 11.0sec with a one-foot rollout) at 131mph (210-212km/h), the M5 Competition may do 0-30mph in 1.3sec (50km/h in 1.4s), 0-60mph in 2.9sec (100km/h in 3.3s), and 0-100mph in 6.4sec (160km/h in 6.3s -- 200km/h in 10.8s).

With an estimated quarter-mile time of 11.1sec (or 10.8sec with a one-foot rollout) at 133mph (213-215km/h), the M5 CS both may do 0-30mph in 1.3sec (50km/h in 1.4s), 0-60mph in 2.8sec (100km/h in 3.0s), and 0-100mph in 6.0sec (160km/h in 6.0s -- 200km/h in 10.3s).

The M5 CS is the track-oriented version of the M5 Competition which also happens to be significantly lighter (especially for the European market, but also a slight bit for the North American market).

Top speeds are 155mph/250kph (and 189mph/305kph with the M Driver's Package).

The BMW M8 Gran Coupe is actually a fastback'd M5 with the same mechanical engineering. It's a bit heavier, too.

## Audi RS 7 Sportback & Porsche Panamera Turbo S â€” 592-621 bhp (590-605 lb-ft)

(Images Credit: Audi, Porsche)

The Porsche Panamera, like the Audi S8, comes in two wheelbase forms; a short one and a long one. Porsche markets the Panamera Turbo S with 620bhp and 604lb-ft in the US market, but almost elsewhere it's 621bhp and 605lb-ft. However, the Audi RS7 that is mechanically related to it only comes in one wheelbase format, and it is detuned to 592bhp (591bhp for the US market) and 590lb-ft of torque.

With an estimated quarter-mile time of 11.9sec (or 11.6sec with a one-foot rollout) at 125mph (200-202km/h), the RS7 may do 0-30mph in 1.6sec (50km/h in 1.7s), 0-60mph in 3.5sec (100km/h in 3.7s), and 0-100mph in 7.8sec (160km/h in 7.7s -- 200km/h in 11.8s). The top speed is 155/250 (standard), 174/280 (Dynamic), or 189mph/305kph (Dynamic "plus") -- governed in all three case scenarios.

With an estimated quarter-mile time of 11.8sec (or 11.5sec with a one-foot rollout) at 127mph (204-205km/h) [124mph (199-200km/h)], the Panamera Turbo S [Executive] may do 0-30mph in 1.6sec (50km/h in 1.7s) [1.2 sec (1.3s)], 0-60mph in 2.9sec (100km/h in 3.1s) [3.0sec (3.2s)], and 0-100mph in 7.3sec (160km/h in 7.2s -- 200km/h in 11.2s) [7.5sec (7.4s -- 11.5s)]. The top speed is 196mph (315km/h).

## Cadillac CT5-V Blackwing â€” 668 bhp (659 lb-ft)

Image Credit: Cadillac

Like its smaller sibling (the Cadillac CT4-V Blackwing), the CT5-V Blackwing will also come with six-speed manual and ten-speed automatic transmissions with power delivered exclusively to the rear wheels. The Chevy Camaro ZL1-derived 6.2-liter supercharged V8 Blackwing will be the last V8 sedan Cadillac will make.

With an estimated quarter-mile time of 11.9sec (or 11.6sec with a one-foot rollout) at 130mph (208-210km/h), the automatic CT5-V Blackwing may do 0-30mph in 1.7sec (50km/h in 1.8s), 0-60mph in 3.7sec (100km/h in 3.8s), and 0-100mph in 7.3sec (160km/h in 7.3s -- 200km/h in 10.7s).

With an estimated quarter-mile time of 12.1sec (or 11.8sec with a one-foot rollout) at 126mph (202-204km/h), the manual CT5-V Blackwing may do 0-30mph in 1.6sec (50km/h in 1.7s), 0-60mph in 3.8sec (100km/h in 4.0s), and 0-100mph in 7.9sec (160km/h in 7.8s -- 200km/h in 11.8s).

Cadillac claims a top speed of "over 200 mph (320km/h)." Based on the 0-60 and quarter-mile estimates, it is likely that top speed is going to be 205mph (330km/h) for the manual version and 209mph (337km/h) for the automatic version.

## Dodge Charger SRT Hellcat â€” 717-797 bhp (656-707 lb-ft)

The Redeye version of the Dodge Charger SRT Hellcat is the most powerful sedan on earth! It has a 6.2-liter supercharged mill that came from its Challenger sibling. 797 horsepower and 707 lb-ft of torque enables this car to do constant 10-second quarter-mile runs.

With an estimated quarter-mile time of 11.3sec* (or 10.96sec with a one-foot rollout) at 125mph, the standard Hellcat Charger may reach 0-30mph in 1.8sec (50km/h in 1.9s), 0-60mph in 3.6sec (100km/h in 3.7s), and 0-100mph in 7.6sec (160km/h in 7.5s -- 200km/h in 11.2s).

With an estimated quarter-mile time of 10.9sec* (or 10.6sec with a one-foot rollout) at 129mph (208km/h), the Redeye version of the Charger may reach 0-30mph in 1.7sec (50km/h in 1.8s), 0-60mph in 3.5sec (100km/h in 3.6s), and 0-100mph in 6.8sec (160km/h in 6.8s -- 200km/h in 10.2s).

*NHRA certified. The Redeye Hellcat Charger is likely to do 11.2-11.4 quarter-mile times on a real-world prepped surface; the standard Hellcat will likely do 11.5-11.8.

Top speeds: 196mph (315km/h) for the Hellcat and 203mph (327km/h) for the Redeye.

With electric cars it wonâ€™t be long before 1000 bhp becomes to norm.

It seems like only those three established German brands and Jaguar like to govern top speeds; I hate that idea. So basically since, let's take BMW for example, that automaker tends to be SUPER conservative with their 0-100km/h in MOST of their models (except for the M2 series), using these estimations for the M5 series shows clarity of these cars using an Americanized one-foot rollout; actually, even German and British testers these days are starting to get used to the rollout (see: Auto Bild, CarWow).

Using the 3.4s 0-100 and 11.1s 0-200 kph claims, the standard M5 appears to have an estimated top speed of 306 kph (right on par with manufacturer's governed claim). Adding 0.3s to both metrics show a huge difference; 3.7/11.4 = 325 kph (only 1 kph off the Maserati Ghibli Trofeo, but a whopping 12 kph off the Cadillac CT5-V Blackwing!). The M5 Competition's 3.3/10.8 equates to a bit less than 306 (on the higher side of 305), and adding 0.3 (3.6/11.1) shows a true 324kph top speed; maybe its more traditional NA-like peak power (6000rpm rather than the usual wide gap) and larger tires hold it back from beating the standard M5. The M5 CS, however, tops out at 311kph only, based on the estimate of 3.3/10.6 (derived from 3.0/10.3) - likely because of aero.

For the M3 series, I'll take sort of a different approach - I'll use the M5 formula for the standard model. 4.1/14.1 = 291kph (right on par with manufacturer governed claim), add 0.3 and it's 4.4/14.4 = 306kph (2kph higher than CT4-V Blackwing). For M3 Competition, it's kind of different - 3.9/12.2 = 320 km/h even with rollout (ridiculously high for 510PS car; 13kph higher than Giulia QV and only 2kph off XE SV Project 8!). Maybe the rear-wheel drive (vs. Jag's AWD) and instant and low-end torque (vs. Alfa's semi-weak Ferrari-like torque curve) makes it easier to manage the power.

I think it's much easier to use the Mercedes-AMG models. For E63 series, 0.something second addition needed to estimate top speed; opposite for C63 series. E63 585PS: 3.5/11.8 = 297 kph (similar to 300kph governed claim), but 3.8/12.1 = 314kph (actually not bad top speed for 585ps midsize AWD sedan). E63 S 612PS: 3.4/10.4 = 327kph (sounds about right for 612ps sedan); my guess is maybe Mercedes-Benz didn't use rollout for E63S claims, while they did for base E63 -- 3.1/10.1 = 307 kph (maybe a slight edge above manufacturer governed claim). C63 476PS: 4.1/12.8 = 320kph (kinda high even for compact sedan with 476ps); 3.8/12.5 = 304 kph (much more accurate; considering governed claim is 290kph). C63 S 510PS: 3.9/12.1 = 322kph (still kinda high vmax); 3.6/11.8 = 305kph (governed claim 290kph). It seems obvious that Mercedes didn't claim rollout with C63 series.

What do you think?

Posted in the wrong section. The F40 is the only supercar mentioned in the story.

Some trucks, off-roaders and even buses produce more power than the 30yo Fezza. Would you write about those in the 'Supercar Community'?

Good point! It was hard choosing which tribe to put it in. I put a shorter version of this article into Muscle Cars.

I changed the tribe for this article per your request :)

Cough cough HSV GTS, GTSR, GTSR W1,

I wish they were still in production!
