Is it faster than Rimac Nevera?

Is it faster than Rimac Nevera?

As we can see, after 300 kilometers per hour, lotus begins to overtake rimac, and the conditions for its acceleration were not ideal

Interesting. Maybe the Lotus really is that much lighter.
And how is Battista so slow compared to Nevera? They must have overclocked the Rimac to the absolute limit for those tests
Plus on top of that, I think the Nevera speedo readout is most likely true speed based on GPS, while the other two probably have a little bit of tolerance in them.
GJ on the comparison!

I doubt the Battista is GPS - you are required to have a speedometer by law, and it also has to work in tunnels and under bridges, which GPS doesn't. Otherwise I guess a lot of cars would have GPS speedometers by now.

I wouldn't really worry too much about speedo measured acceleration in any case. Just not reliable. Apart from there being often 10-20km/h discrepancy at high speeds, it's also easily gamed by putting on tires with a slightly smaller diameter than what the speedo is calibrated for.

Maybe we can say that the Evija is roughly the same as the Nevera, but even that is hard to say definitively. Does it weigh less? I mean, it bloody well should considering it only has 90kWh battery compared to the 120kWh of the Nevera. And it has 160PS more, so it should be faster overall. The only problem with the car is, that it has equal power distribution front and rear, while all the other high performance EVs (Plaid, Nevera, Sapphire) have roughly 2/3rds of the power going to the rear. This means that under acceleration, under the weight transfer that occurs, for the Evija there might be some sections when it can't apply full power, while the others can. That might, in part, explain why it's only as fast as the Nevera - if we were to pretend that these speedo comparisons mean anything.

Four equal motors is pretty strange move from Lotus. I guess simplifying the development was the priority for the team. Do you think the other practical benefit of that setup could be improved brake regen?

I don't think so. The limiting factor to brake regen isn't the motor generating capacity, but the battery. Even if the Evija battery can discharge at 1.5MW, it can probably only accept up to 500kW from brake regen, but likely way less. On the Nevera the brake regen maxes out at 300kW, for example, and that may be further limited by invertor/battery temps and battery state of charge. So I don't see any need for the Evija's front motors to be 750kW.

Even if they could charge the battery at 750kW with brake regen, I still don't think that would justify gimping acceleration. So, is it a strange move? Yeah, I would say so. Can't really think of any explanation why they would do that. Maybe we'll hear some one day.

Correct. In an EV, you can't dial acceleration, top speed and regen to 10. For all three, heat is a limiting factor. Therefore we can expect to see variations in the trade-offs that manufacturers choose for their flagship performance EVs.

Are these production or development cars?

Are these production or development cars?

That one looks like a production car. Maybe they have started delivering them?

Nope, a pre-production car. The same one that was at Goodwood FoS last year. No real deliveries yet.

 

[Tourbillon]

Lotus Evija Ex definitely.

Lotus sticking to it's "ethos" and making a car that can only corner, but not go in a straight line...

Lotus sticking to it's "ethos" and making a car that can only corner, but not go in a straight line...

Lotus engineers overheard saying that these motors were going to “drive them round the bend”.

 

[Sunny]

That is new twist to "smoke and mirrors".

 

[Bucketslash11]

maybe go for a timed run first before showing off

 

[bmwz4coupe]

Who’s the driver?

 

[Revvd]

WHAT REALLY HAPPENED TO THE LOTUS EVIJA X AT THE FESTIVAL OF SPEED?
TLDR: Hyper EVs are uncontrollable without traction control limiting the torque. And Lotus found out the hard way, having never done a burnout before.
Contributing factor: the car lined up to the start line at an angle due to stalled Solus GT ahead in the queue.

 

[Bridster]

The normal Evija didn't actually look that stable either. Had a couple of uncertain moments during some of the runs. I wonder how long it's gonna take Lotus to finally sort the car. Or if that's the best they could do.

They did the first "show delivery" at last year's Pebble Beach... and now almost a year later still no deliveries. Although, maybe that has nothing to do with them sorting the car out dynamically, who knows.
