McLaren Speedtail: Geneva 2019
McLaren confirms 1,070hp for its petrol-electric hypercar ahead of public debut - including 313hp from new battery tech
Given Ferrari is revealing a new V8 berlinetta at Geneva and Lamborghini has released convertible versions of both its supercars, you could be forgiven for thinking McLaren might be a little left out, showing a GT3 car and MSO specials.
Not to be outdone, it has taken the opportunity to confirm new details about the upcoming Speedtail's powertrain. Previously we knew the car would be capable of 250mph, making it the fastest McLaren ever; now we know exactly how it will go about achieving that.
A parallel hybrid without any EV range, the Speedtail will feature the familiar 4.0-litre turbo V8, with 757hp and 516lb ft, plus a new electric powertrain providing 313hp and 258lb ft, for a total of 1,070hp and 774lb ft.
More interesting still are the advances in battery technology. The batteries in a Speedtail weigh nearly half that of a P1's battery pack at 52kg, yet boast four times the energy density. So in 2013 96kg of batteries enabled 179hp and 192lb ft; just half a dozen years later and 52kg proffers 313hp and 258lb ft. Which is pretty incredible.
The Speedtail will also be fitted with with wireless charging (see diagram), and can't be plugged in. As for how long the powertrain can stay at the full 1,070hp, it's currently too early to tell. You'll remember the requirement for a P1 was a flat out, full lap of the Nurburgring; given the Speedtail's more relaxed remit - 250mph v-max notwithstanding - it might be less than that.
Whatever the case, this sort of information promises to keep interest in the Speedtail maintained for a little while yet. Expect a little more soon!
The ability to get energy out of the batteries quickly may be markedly increased, along with more powerful motor(s), but I doubt the cells themselves have anything more than an incremental energy density increase as might be expected with the general trend for improvement in the six years since the P1 was developed. The fact that it has zero EV-only range tells us something about the way in which the Speedtail uses its electrons, a much bigger hit for, presumably, a shorted period.
You need to be careful with stuff like this, duff info travels far and wide.

How fast can you make (~push) a car go = Force x speed = power = W ~ kW ~ hp ~ bhp = energy / time = amount of energy released in a certain time ~ V x I (voltage times current) ~ amount of fuel an engine burns in a certain time (x efficiency)
