The Regera's unique single gear transmission is what makes it supersonic

Should hypercars of the future use the same system?

There was a time in human history when we could mentally comprehend and physically appreciate the speed at which the automobile could travel, but in the 90s, McLaren introduced the F1 and with it, the 'hypercar' class was born. In the decades since, technology and engineering has gone from strength to strength, and one company that perfectly embodies the insane speeds that you can now travel at, whilst behind a steering wheel, are Swedish giants 'Koenigsegg'.

Founded in 1994 by engineering marvel, Christian Von Koenigsegg, they tried and perfected their recipe over the next few years and in 2002, released the CC8S - a monster that was capable of hitting 240mph. This car set the tone for their future models, with the CCX, the Agera lineage, and all the other members of their armada, perfectly happy to sit at 250mph - some being able to achieve even higher speeds.

Just when the motoring world thought that the globe's fastest car company couldn't get any more ludicrous, they presented us with the Regera - the vehicle that would go on to be the world's fastest car from 0-400km/h. It wasn't half beautiful either, but what really announced the Regera as the cream of the crop was the fact that it had a rather unconventional transmission.

Fitted with Koenigsegg's ''Direct Drive Transmission'', the Regera was able to operate on just one single gear - an idea that was pulled straight out of the deepest, most spellbindingly fictional automotive story books you can imagine. You're probably wondering what that must look like right about now, and here's the answer:

This footage was recorded at the stretch of airstrip, right next to Koenigsegg's fabled Ängelholm factory. When you observe the revometre, you can see that the Regera's engine, a twin-turbocharged 5.0-litre V8 with three electric motors, revs at roughly 5,000rpm up until about 137mph, after which the motor really springs into life and utilizes the full red-line. What else do you expect from 1,500bhp?

As previously stated, the Regera was and still is the fastest accelerating car from 0-400km/h, or 248mph, with a time of just 31.49 seconds. How insane is that? The car managed to eclipse the previous record for that speed by nearly two seconds - also held by Koenigsegg with their Agera R. To put this into perspective, the Chiron takes a full 10.2 seconds longer to hit the same speed, which just begs the question: Is this single-gear transmission the way forward for humanities ever-present need for speed?

  • Damn that was an amazing read. I always wondered how much faster the Regera was (compared to the Chiron in terms of hitting the top speed).

  • Every, well almost every, EV has just 'one gear', usually a reduction 'torque multiplier' gear between the motor and the wheels. Hardly new or revolutionary! The only reason ICE vehicles have a geared transmission at all is to compensate for the engine's inability to produce a wide enough power-band not to need gears. Incidentally, the purpose of a 'gear box' is to hold the lubricating oil in, not so much the gears themselves (which would still function in a framework, if only for a short time). Some EVs are 'direct drive', with a motor located inside the wheel hub. This increases unsprung weight, which is not a good thing. You want as much difference between unsprung weight and sprung weight as you can, because a heavier body will thrust the wheels back onto the road against spring pressure much more quickly, thereby ensuring the longest period possible for tyre contact... kind of obvious when you think about it.

  • It’s unnerving how the speed builds so fast without that much audible drama from the engine

  • Would be interesting to accelerate with the same rpm on the engine, the whole run. 😁

  • It’s like a hypercar CVT. Maybe great for acceleration, but what’s it like when you want engine braking? What’s it like on a track as opposed to drag races?
