The Ford Mustang Shelby GT500 Can Actually Top 210 MPH (338 KM/H)
The top speed of the 720-plus-horsepower Shelby GT500 is governed to 180 miles per hour (290 kilometers per hour), but there will be an easy, aftermarket(ish) way to remove the limiter. The previous-generation model with 662 horsepower could hit 202 mph (325 km/h), and multiple reports in the 2017-2018 period were predicting a maximum speed of 214 mph (345 km/h) for the new 720-horsepower car. The two main reasons why Ford governed the top speed on the new car to 180 mph (290 km/h) are because the development of the new car is costly and the car has already been tuned to compete with the major players on the race track.
This is basically Ford's (indirect) Shelby GT350 successor with a supercharger.
The 2020 Ford Mustang Shelby GT500 is claimed to accelerate from 0-60mph (97km/h) in the mid-threes and complete a quarter-mile in just under 11 seconds. Vimulator's results are on par with Ford's claims with 0-60 in 3.37 seconds and the 1/4-mile task done in 10.98 seconds.
The GT500 has been reported to produce a conservative 720 bhp (537 kW) and 650 lb-ft (881 Nm) of torque and weigh in at 4225 lb (1916 kg). Include the driver and that weight bumps up to 4390 lb (1991 kg) per EU standard.
The GT500 is displayed topping out at 180.5 miles per hour (290.5 kilometers per hour) with a kinetic energy rating of 1,867.8 watt hours. That equates to a test weight of 4554 lb (2065 kg), which could indicate that a passenger has been added along with the driver.
The likelihood of reaching 210 mph (338 km/h)
Because the top speed is governed, let's start spicing things up a little by increasing the road grade and increasing the tailwind for a negative wind speed, level-by-level:
Level 0 -> 0% road grade & no wind speed -> 180.5 mph (290.5 km/h)
Level 1 -> +3% road grade & -20mph (-32km/h) wind speed -> 187.9 mph (302.4 km/h)
Level 2 -> +6% road grade & -40mph (-64km/h) wind speed -> 191.8 mph (308.6 km/h)
Level 3 -> +9% road grade & -60mph (-96km/h) wind speed -> 198.9 mph (320.2 km/h)
Level 4 -> +12% road grade & -80mph (-128km/h) wind speed -> 205.1 mph (330.1 km/h)
Level 5 -> +15% road grade & -100mph (-160km/h) wind speed -> 210.0 mph (338.0 km/h)
(𝐃𝐢𝐬𝐜𝐥𝐚𝐢𝐦𝐞𝐫: Using these levels won't work on all cars, but mostly on ones that have top speeds set lower than expected, such as the "180mph" GT500.)
If the GT500 happens to (without the limiter) max out at 187 or 191, then unless it was built for setting lap records, it won't be the king of (modern) "muscle cars." If it happens to top out at 198, then it will be on par with the Chevy Camaro ZL1 (198) and Dodge Challenger Hellcat (199). However, 205 or 210 seems like a tricky top end, especially when the Hellcat Redeye tops 203. The four-door Charger Hellcat tops 204. But the GT500 appears to be more aerodynamic with a smaller body than either Hellcat.
Anything past 205 mph (330 km/h) is already supercar territory. A Camaro ZL1 would be able to hit 215 mph (346 km/h) with an additional 105 bhp (78 kW), but this is due to the fact that it is capable of both 198 and 215 in eighth gear with peak power closely attached to the top speed rpm's.
At 210 mph (338 km/h), the GT500 is already eclipsing all of the modern "muscle cars" and even a few supercars such as the Bentley Continental Supersports (209), Dodge Viper (206), Chevy Corvette Z06 (limited to 196), Audi R8 Performance (205), Ferrari 488 GTB ("over" 205), and McLaren 600LT (204). The Aston Martin DBS Superleggera (211) is barely faster.
Even if the GT500 only topped 200 mph (322 km/h), it is still going to destroy at least the "standard" 717-horsepower Hellcat, if not the Redeye, in terms of acceleration.
