Detroit - This is the car that GM is hoping will make green sexy in the US - the Cadillac ELR extended-range electric car, making its world debut at this week's Detroit Motor Show.
GM claims that the ELR, based on the Converj concept, is the first luxury extended-range electric car, and shows the way forward for the Cadillac brand, with sleek, modern exterior proportions, while the interior introduces a new design theme that will define future Cadillac models.
Motorvation is provided by a potent electric motor - GM quote 154kW and 400Nm, although they carefully avoid mentioning performance figures - and a huge, T-shaped, 1.6-metre long, 16.5 kWh, 198kg lithium-ion battery.
That's good for about 56km of gentle driving, says GM, depending on speed, load and ambient temperature; after that the ELR's 1.4-litre petrol engine chimes in, not to drive the wheels but to power a generator that'll keep the electric motor amped up for another 400km.
Save the battery power for when you really need to sneak around in silent mode.
