What’s the fuss all about……….
The Koenigsegg Regera sits on a highly modified Agera chassis, here significantly changed to accommodate a 9kW battery pack in the centre of the car, which we’ll get to shortly.
This means the entire front end had to be reworked, while the rear chassis – in a first for Koenigsegg – was fitted with new rubber mounts instead of solid ones, to provide more comfort and quietness.
Then there’s the drivetrain: Koenigsegg’s proven 5.0-litre twin-turbo V8 sits proudly in the middle, pumping out a healthy 1100bhp alone, direct to the rear wheels.
But instead of being attached to a normal transmission, the Regera uses something called the Koenigsegg Direct Drive system. There’s a small, crank-mounted electric motor to fill the torque gap (and act as a starter motor) together with a hydraulic coupling.
Each rear wheel then gets its own electric motor, and we’re told that triplet of electric motors amounts to around 700bhp alone. Christian tells us that from take-off, with the coupling open, you power off purely on electric drive, with no need for a gearbox. As soon as it gains a few more revs, the hydraulic coupling begins to close, and the smaller crank-mounted electric motor joins in to help the bottom part of the torque curve.
And then finally, once the engine gets up to speed, that kicks in from around 30mph upwards. “We managed to take a heavy, expensive lump out of the equation [the transmission], without sacrificing the ability of the combustion engine to provide drive to the rear wheels,”.
The Regera is rear wheel drive only, so 0-62mph takes a relatively tardy 2.7 seconds. “We can’t go any faster than that because of traction,” Christian says. 0-186mph takes 12 seconds flat, while 0-250mph takes under 20 seconds. It’ll go from 93mph to 155mph in just 3.2 seconds, and top out at 255mph. Let those numbers swirl around your head for a moment.
