RE: Lotus Evija to target Nurburgring record

Zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Oh, sorry, WHAT? Where was I? Oh yes: zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
Some people think the key to Lotus success was Lightweight but it wasn't, it was Innovation.
Lotus didn't always invent a concept but they utilised it in such a way that made a forgotten idea popular. During the 25 years that Chapman ran Lotus they pretty much single handedly changed the face of motorsport and many other car companies owe a lot to Lotus. Companies like Ford, Alpine and Caterham. Lotus going electric is precisely what Lotus should be doing, they need to be at the cutting edge.

2000bhp hypercar likely won't make a loud brum noise,is therefore boring.I've said it before and I'll day it again (and be correct), everyone saying how boring electric hypercars are would give their left nut to pilot one round the ring in anger.
"the 70kW/h battery pack has been designed to deliver its 2MW peak flow for up to seven minutes"
A 70kWh battery back discharging at 2MW, will last for 0.035 hours or 2 minutes at 6 seconds. I am not sure I make much of their technical presentation. Of course it won't be full power all the time, but will it even make it round a single flat out lap of the Nurburgring? It sounds like the battery pack is way too small for the level of power this car packs.

You should probably address these concerns to Williams Engineering as it's their pack. They supply the batteries for Formula E.A 70kWh battery back discharging at 2MW, will last for 0.035 hours or 2 minutes at 6 seconds. I am not sure I make much of their technical presentation.

I assume they are talking about the thermal design - ie. you can absolutely cook it for seven minutes and you won't end up with a puddle of lithium and a car in limp home mode.A 70kWh battery back discharging at 2MW, will last for 0.035 hours or 2 minutes at 6 seconds.

When driving a "lap" then you can recover significant energy via regen, the slower the average speed the higher the energy percentage you can recover. And of course, the powertrain is not at 100% power even when you are accelerating (due to traction limits).A 70kWh battery back discharging at 2MW, will last for 0.035 hours or 2 minutes at 6 seconds.

Worst case is Vmax, where all your battery energy goes 100% into drag. If we assume this car can do 230mph, then 2.06 min at that speed is a distance of around 8 miles, so you'd need to find an 8 mile long "straight" to do that? (Nardo HST is juuust about big enough, but with a neutral steer speed of just 150mph, at 230mph the tyres are getting a beasting and the tyre drag is significant, the Koenigsegg CCR, did 241 there back in 2005)
They also don't mention how long you have to wait after you've done a full battery depletion at max power, before you can charge it again at any high C rate...
For example, the IDR has onboard and offboard battery cooling for a faster turnaround:
Note the force air cooling hoses!

Why would it fart? It's electric. At least read the story before pouring scorn all over the product.
I sense irreverence is not something you understand?I am well aware it is electric, I have read about the car well before it arrived on PH.
But keep condescending if it makes you empowered.

I can appreciate that people have different things that appeal to them.
And all I did was express that on a public forum for debate.Opinion, that's all and as covered above I am well aware it's electric, my point about Goodwood was not meant to be descriptive as to its sound...

Lotus doing things different..
And then banging on about a Nurburgring time again. How may times is a production one of these actually going to do that? It's a meaningless statistic!
If we were talking about a diesel ford, I'd agree. But this is designed as a hyper car. Everyone wants to know how fast it is. How fast it is will be one of its defining factors, not how much shopping it can carry.And then banging on about a Nurburgring time again.

There’s a lot of learning to be done on this car that will benefit Lotus greatly over the next 20 years.
What other car has true 4 wheel torque vectoring? No one. Getting ahead of the game here will be the true game changer for vehicle dynamics over the next 10-15 years.
This makes a lot of sense. "Game changer" is appropriate, though did not Mclaren have something similar on the P1 ?What other car has true 4 wheel torque vectoring? No one. Getting ahead of the game here will be the true game changer for vehicle dynamics over the next 10-15 years.

They're well aware of that, I'm sure.
Are people really daft enough to see the Evija as a RotM model to make money? It's the halo. It's only purpose is to draw attention to the new and improved Lotus under Geely and prepare the market for future, profitable products.
Tech trickle down too.Are people really daft enough to see the Evija as a RotM model to make money? It's the halo. It's only purpose is to draw attention to the new and improved Lotus under Geely and prepare the market for future, profitable products.
