Speedtail McLaren Speedtail (BP23 Project)

But we have to admit, design wise it's a breath of fresh air. If you like the design or not, it's special in every way.

I think it makes a big impression in person. The design so pure compared with the Laf, 918, Chiron and Huayra.

Initially, I liked the 1990's sci-fi-ness of it. The recent pics though... In red, it reminds me of the GM EV1. I'd go for a lighter, more sober color to really highlight that ethereal, lithe look.

Looks like a concept car from the 80s

The stretched out silhouette reminds me of the XJ220.

i wonder what the drag coefficient is

and why didn't they put a skirt over the rear wheels? they already have covers over the front wheels so i see no reason to holding back with the rear wheels

 

[WBarnes]

Are the wheel covers an aerodynamic thing or a KERS thing though? Does the BP23 have KERS?

Sorry, I actually meant the covers over the front wheels in my post above.

From google. The carbon fiber covers on the front wheels reduce air turbulence around the wheel arches. So it is aerodynamic.

McLaren says it hit 250 mph 30 times and you're telling me they didn't even record a single run?

Not that simple in the UK. The F1's run was done on Ehra-Lessien before VW became pissy about other people using their track.

it is that simple the runs were done at the Kennedy Space Centre on their 15000 ft space shuttle landing facility runway.

maybe we'll see a video soon, Johnny Bohmer Proving Grounds does have a youtube channel

I think Mclaren is honest on their top speed claim, judging by the numbers their cars achieve constantly in magazines...

The aerodynamic front wheel cap seems to be a little different on these last pictures?

 

[WBarnes]

It would struggle not to hit 250mph with 1036hp.

With over 1000PS and that aero shape it should hit at least 410 to 420kmh depending on the gearing. The F1 achieved 391kmh just with 627PS and this car is probably even more aerodynamic.

Has drag or tyre resistance increased over the decades since the Mclaren F1?

Surprisingly yes if you compare the HyperCars from just a few years ago to the F1. The F1 had a low overall drag of just 0,57 as its frontal area is only 1,79m2, which is much lower than most cars as it is both low at 1,14m and narrow at 1,82m compared to a Veyron which is 1,204m H x 1,998 W.

“The overall drag coefficient on the standard McLaren F1 is 0.32, compared with 0.36 for the faster Bugatti Veyron, and 0.357 for the SSC Ultimate Aero TT, which was the fastest production car from 2007 to 2010. The vehicle's frontal area is 1.79 square meters, and the S·Cd figure is 0.57.”

I don’t have the dimensions for the Speedtail except read that is narrower than the P1 (1,947m) and just 1.12m at its high velocity setting. Also read somewhere that it’s CD is approx. 0.275, so it should reach 410kmh easily.

I think the F1 did "only" about 371 km/h in one top speed test, the other where it went faster was done with some tricks if I remember right...?
