Although they don't yet mention a diesel engine option, the announcement of a new Saab crossover today does say that it will go on sale in Europe next year. That suggests there will be a diesel, because otherwise they're at nothing over here.
Meantime, the car will debut at the Los Angeles Auto Show as the production version of the Aero X concept, with a 2.8 V6 turbocharged petrol engine outputting 300hp, clearly aimed at the US where it will launch in May.
Sizewise it fits between the 9-3 and the new 9-5. It will have the XWD all-wheel-drive system and offer a number of driving modes.
With the petrol engine, the performance is an 8.3sec 0-100km/h. Fuel consumption and CO2 details have yet to be released.
