EVs and In Gear Acceleration vs ICE

The old go to measure of an internal combustion engines flexibility used to be timed between 50 to 75 or 50 to 70mph in 5th or 6th gear.

With the new EVs now does their instant electric shove only mean they are quick from a standing start or are they just as instant in the mid ranges like the old 50-70?

Its not a subject I think Ive seen in any reviews or the comparisons to ICE stablemates. Also many seem to be limited to 112mph but I guess thats due to what is essentially only having a single gear..

Tesla compared to Bugatti Veyron

Annoying that they've ruined the braking comparison by testing the Veyron at 6C Vs 17C for the Tesla.

In any real world conditions and up to 100 mph there isn’t anything that will really touch moderate to high end EVs. The power is also far more accessible with an EV and you can much more reliably put the power down.

TX.

I use my supercharged 5.0 V8 for this.

Funnily enough an XFR had a pop at me last weekend. It couldn't keep up with my Tesla Model 3 LR, although obviously it did look and sound a lot better than my Tesla.

It wouldn't have seen which way my supercharged 4 had gone though...

EVs could go quicker but they would need a gearbox. The limit with the Tesla Plaid is the rotational speed of the motor, it has to be carbon fibre wrapped to stop it spinning apart. But there is no sense on adding a gearbox to a car when it won't need the higher gears 99.9% of the time.

The Porsche Taycan and Audi etron GT have a 2 speed gearbox.

My ICE car has 550 bhp per tonne, my EV has 295 bhp/ tonne and subjectively feels as quick. Objectively it’s not far off either.

Up to around 120mph there’s not much that can keep up with a performance EV in my experience.

More ordinary sports cars (911’s, M3/4’s etc) aren’t even in the same ballpark.

That article reiterates the point I was making previously but got shot down in flames on PH for - EVs despite their reputation for being drag light queens, are actually not that great off the line, so the traditional 0-60mph metric understates their real-world performance.

What car have you got 540torques? Sounds a pretty serious bit of kit!

It's a 2004 JDM STi with a high compression 2.1 using a bespoke twin scroll ball bearing core turbo. It's a daily driver, but i built the engine to win a sprint championship whilst remaining normal to drive daily.

It looks stock and uses mostly stock parts, but is quite trick in the areas that make it so quick as a road car.

For a relatively normal EV to match it's road speed acceleration is pretty impressive, they wouldn't match it at higher speeds but thats not usable on the road.

I've only had one chance to do a side by side test with a Tesla model 3 on acceleration, and mine left it behind quite easily. Mine will do 0-60 in 3 Seconds though, when using launch control.

A Tesla Model 3 Performance will do 0-60 in 3.2s

Pretty quick then, the lower spec M3 seem to be a fair bit slower according to this review. https://www.evo.co.uk/tesla/model-3/performance
Still quick for a shopping trolley though.

Ev’s still outperform ice into triple figures but then tail off and ice wins top speed.

Many can't even make triple figures...

Last time I hit triple figures was the 1980s! (private track)
Irrelevant this century..

There's some efficiency to gained having a 2 speed gearbox for city and highway. I believe some twin motor cars avoid this by using different ratios in each motor.

Nah.

That's just showing off.

I bet it struggled to get the power down. Did you do any road tyre on the road acceleration tests?

It was pretty horrible tbh and would spin the tyres at over 100mph. 6.6L supercharged stroker V8 LS truck engine. Shorter stroke now which helps with traction but it’ll still spin the tyres all the way to 70mph if you poke it. PD superchargers give boost off idle as you can see. And I get a savage V8 soundtrack to go with it.

It was a real heart over head decision when I bought it. It looked and sounded superb and was wickedly fast. The dealer was really good but the car was so problematic It had to go back as I'd lost all confidence in it so I never got to take it on a track. Anyway live and learn.

Mine was too loud to go on the track (118dB, 108dB with trackday silencers).

Not in all cases... Model X Plaid vs 810hp Nismo GTR - the Tesla gives it a good shot well into triple figures - the rolling races later in the video are more impressive than the drag race due to showing the acceleration at higher speed.

They were at least sporting and gave the GTR a chance by putting it against the X rather than the S :

First of all, no diesel engine has instant torque, not like an electric motor.

Secondly, having to compensate for the ridiculously peaky torque curve of any fossil engine with a mechanically complicated box full of gears is well past its sell by date.

And finally: all drivers are lazy. If they weren't, they'd walk, or ride a bicycle.

What a load of balls. EVs are boring and only faster when compared to their average ICE competition. They don’t define high performance at all. Line one up against a top fuel dragster and see how well it does. For a few grand I could bolt a turbo to my ZZR 1400 motorbike and with say 300hp on pump fuel, your performance Tesla wouldn’t stand a chance. It’s just EV owners drinking their own coolaid because they’ve never owned anything quick before.
