Audi has had its fair share of criticism from plug-in car fans, but the automaker now seems to be coming around to the idea of electric propulsion after some rather public dismissals of the technology.
Audi's first production plug-in model will be the A3 e-tron plug-in hybrid arriving next year, but the larger A4 sedan could now follow that lead in 2015.
Autocar reports the 2015 Audi A4 could come with not one, but three plug-in hybrid models--offering varying degrees of efficiency and performance.
In addition to the usual range of gasoline and diesel models, the A4 could use variants of a 2.0-liter, 220-horsepower gasoline engine, a 180-hp 2.0-liter diesel, and a 250-hp version of Audi's current 3.0-liter supercharged V-6.
The full hybrid power figures are likely to be higher than those above. For perspective, the A3 e-tron's plug-in hybrid drivetrain uses a 1.4-liter gasoline engine and electric motor to develop a combined 204 horsepower--not far from the 2.0-liter engine on its own.
Layout should also be similar. Autocar says a 110-hp electric motor will live within the gearbox casing, just as it does in the A3. In the A3, power is transmitted through a dual-clutch automatic transmission, but the new cars could use an 8-speed gearbox.
Regular gasoline and diesel models should see a step up in efficiency--the former are likely to incorporate cylinder deactivation technology--while heavier use of aluminum should see curb weight drop by as much as 220 lbs on the base model.
Styling should be more evolutionary than revolutionary--but intricate detailing and sharp body creases will be the order of the day.
