ounting pressure to reduce emissions is driving
the likes of McLaren, Ferrari and Aston Martin to
electrify their core ranges – and not just their
big-money, Speedtail-style flagships. Motorsport has proved
the good sense of turbo engines and electric motors working in
concert, but squaring the advantages of electrification with the
weight penalty batteries inevitably bring will not be easy...

Jens Ludmann: ‘Emission requirements are undoubtedly
driving the move to performance hybrids, but it’s also about
the torque-feel of an electric motor, the instant response: this
is very good when you are engineering a sports car. And with a
hybrid you still have something of the power-to-weight ratio of
a combustion engine. By 2024 all Sport Series [570S and friends]
and Super Series [720S] McLarens will be hybrid.’

Christian Von Koenigsegg: ‘Before the Regera, I was quot-
ed many times saying I did not like hybrids. But there is a big
difference. It is the parallel hybrid [Prius, McLaren P1] I disliked:
a full combustion engine and then, in parallel, electrification.
This is complicated, expensive and heavy, since you are adding

to the system but not removing anything. Series [BMW i3] is
simpler, and you can remove the gearbox. The result is cheaper
and lighter but you have increased losses, since you are con-
verting mechanical movement to electricity and then back to
mechanical movement. The engine is disconnected from the
driving experience, so you have neither the serenity of an EV
nor any sense of connection to the engine.’

JL: ‘When you go for electrification, it makes sense to have a
powertrain developed as a unit. It doesn’t make sense to have an
engine that hasn’t been developed to work with the punch of an
electric motor. But at McLaren the cars we do are driver’s cars.
We introduce technology only when it improves the driving
experience – everything we bring in has to improve this. The
excitement of the combustion engine is secondary. We look at
everything about the car’s performance and, if it’s better with
an electric powertrain, that’s what we will do.’

CvK: ‘With Regera, we were able to remove the transmission,
so there are hardly any more components than you’d find in a
series hybrid, and no frictional losses apart from the final drive.’

‘Electric’s torque-feel is great’

Prius blazed the trail – but now the hybridisation of supercars is gathering pace.
