The countdown to the Shanghai Auto Show continues as Karma Automotive has released new details about the 2020 Revero.

Set to be unveiled later this month, the significantly revised model will have a completely redesigned electric powertrain which includes a more powerful lithium-ion battery pack and a new “twin-motor rear drive module.” The company declined to say how much power the electric motors produce, but said the car will be able to accelerate from 0-60 mph (0-96 km/h) in 4.5 seconds. This is nearly a full second faster than its predecessor.

The electric powertrain isn’t the only thing that is new as the 2020 Revero will also come equipped with a BMW-sourced TwinPower Turbo three-cylinder engine that acts as a generator. Karma was coy on specifics, but confirmed they have been working with BMW since 2015.

Little is known about the Karma’s engine, but the BMW i8 has a 1.5-liter TwinPower Turbo three-cylinder that produces 228 hp (170 kW / 231 PS) and 236 lb-ft (320 Nm) of torque. It helps to give the model a combined output of 369 hp (275 kW / 374 PS) and 420 lb-ft (568 Nm) of torque.

Regardless of how much power the engine develops, Karma Chief Technology Officer Bob Kruse said “BMW AG is a natural fit for Karma’s luxury-tech focus because it is a proven technology leader renowned for conceiving and delivering ground-breaking innovations.” The company also said the partnership showcases how they embrace relationships with “like-minded technology leaders to help spur innovation and speed-up product development.”

Besides the new powertrain, the 2020 Revero will have an updated design with new fascias and restyled lighting units. The cabin could also see some updates, but nothing is official as of yet.

The Revero will be unveiled alongside two different concepts and go on sale in the second half of the year.
