Talk:Jaguar C-X75 R3 Spec Championship (v7.0.5)/@comment-33870577-20190122004108/@comment-27123099-20190122172616

DecadeHansen is sort of correct.

The C-X75 concept was driven by 4 electric motors, one at each corner. There are 2 micro-turbine engines which act as "range extenders" and charge the batteries.

Jaguar did announce a limited production of the car, but they swapped out the turbines for a single, small turbocharged gas engine and reduced the electric motors to two (one at each axle). As they pushed 500hp out of the small 1.6L turbo 4cyl, it definitely was used to power the car in the production models (plus 390hp from the 2 electric motors combined). However, they only built 5 developmental mules and sold 3 of the cars at auction.

There are videos on YouTube where you can hear the car being driven and it's quite clear that the sound is overwhelmingly from the gas engine. Being that the sound is closer to what we hear in the game, these later pseudo-production models are what the cars in this game are developed from.

That said, the additional noise would be from the electric motors. When the gas engine is quiet enough to hear them anyhow, otherwise it drowns them out.
