Abarth CEO Says A More Powerful Abarth 500e Is In The Works!

At some point I believe it would be wise to use a torque-vectoring differential paired with some sort of transmission, even if is only a two speed tranny. A proof of concept was built a number of years ago and shown to FCA people. The drivetrain mule was a Jeep Renegade and the project was done by a known vendor supplying FCA with drive line assemblies.

it was done in the taycan. I think it's easier, cheaper, and more reliable to add more torque and power to a single speed ev than adding a transmission. the thing is to be honest with top speeds. most people never drive over 90-to 100mph. they can be geared low enough that any gears would be a waste.
if you want to reach 200mph, then you are probably geared too high for daily driving. but since the transmission adds constant parasitic loss, the difference in efficiency.
if you compare a Tesla plaid with a Porsche taycan, you quickly realize the Tesla power train destroys Porsche's dual motor with 2 speeds on the rear. more torque, more power, more acceleration, higher top speed (219mph unrestricted), longer range and better efficiency.

but ultimately the future of EVs are 4 small motors, one in each corner, and you can have different gearing front/rear . no more differentials, driveshafts, torque vectoring on all wheels

Production of the Lightyear 0 started today. Link here.

It has 4 small electric engines, one for each wheel.

4 independently controlled in-wheel motors

Lightyear 0's drivetrain began with a blank slate and a radical focus on efficiency.
Its design is truly unique.
Four traction inverters and direct drive-in-wheel motors eliminate the need for energy draining components, such as gearbox and driveshafts.
Our drivetrain is not only in pole position for the highest efficiency on the market, it also reduces the number of rotating components for much lower maintenance. Rigorous automotive testing programs have proven its reliability, and in the harshest of environments.

1,720 Nm Peak Vehicle Torque
130 kW Peak Vehicle Power (170 bhp)
10.5 kWh/100km Energy use at highway speed (100 km/h)
