Fisker Automotive has apparently decided that 260 hp and 260 lb-ft of torque should be plenty of power to recharge some batteries. Those 260 galloping ponies will come courtesy of the General in the form of its 2.0L direct injected and turbocharged Ecotec four banger, an engine that we've sampled ourselves plenty of times. We feel well qualified, therefore, to suggest that this is an excellent motor, but it really sounds like a major case of overkill for this particular application. Perhaps that's better than "underkill" (if such a word actually existed) as that powerful engine ought to be able to recharge the Fisker Karma's on-board lithium ion batteries at an extremely brisk pace. The faster the internal combustion engine can charge up the battery pack, the quicker the car can revert back to its native electric-only operation. Plus, that engine is a relatively light chunk of alloy, so the Karma's motor shouldn't be burdened by the gasoline-fed boat anchor too horribly under electric power.
We also find it a bit interesting that Fisker chose GM as its powertrain supplier, which means that the Karma and GM's own Chevy Volt are now even closer cousins than before. Both vehicles will sport four doors, lithium ion batteries and an extended-range electric vehicle drivetrain; and with this announcement, both are now slated to share four cylinder engines from GM.Source URL: https://automotivetrendnews.blogspot.com/2008/11/fisker-karma-to-use-gm-20-liter-turbo.html
