The Munich-supplied unit powers a generator that charges a new, improved lithium ion battery, which in turns feeds a pair of rear-mounted electric motors. This set-up that allows for a claimed 0-60mph time of 4.5sec – nearly a second faster than the current Revero.
More detailed performance information will be revealed when Karma officially unveils the new Revero at the Shanghai motor show, alongside its new Vision EV concept and a luxury saloon concept developed with Pininfarina.
Originally launched in 2016, the Revero is the model born out of the ashes of Fisker's bankruptcy. Chinese-funded, California-based firm Karma has been selling the model in the US since then and is now planning to introduce it in European and Asian markets after a number of updates to make the powertrain more competitive.
Spy pictures show that the four-door coupé, which will rival the Porsche Panamera 4 E-Hybrid, will get styling revisions to its front and rear but that its overall bodyshape will stay true to the Fisker Karma, from which the Revero was developed.
Karma's chief revenue officer, Jim Taylor, previously told Autocar that the Revero's delayed entry into Europe (including the UK) and Asia was always part of the business plan. Prices for the current model start at $130,000 (£98,124) in the US.
