Audi’s 2014 model year A4 under development is reportedly getting a few environmentally agreeable options, including a plug-in hybrid version.
The rumor is that a fuel-burning engine will drive the hybrid’s front wheels, while a battery-powered electric motor turns the rear. All-electric range could be up to 37 miles, about the same as offered by a Chevrolet Volt.
The Volt is designed to hit speeds up to 100 mph, but the speeds for the A4 running on battery power only are as of yet unknown.
The electric mode in the A4 could be for limited speed driving, as is the case for other plug-in hybrids under development. Whether this is the case, or all-electric highway driving will also be possible will depend on available power from the electric side of the propulsion system.
Based on Audi’s weight-saving MLB Evo platform, the new A4 line will increase in size to compete with the larger BMW 3-Series. At the same time, some versions of the new A4 are predicted to weigh as much as 300 pounds less than the car to be replaced.
Other powertrain options will likely include a TDI and gasoline-burning versions. Stop-start technology is also expected to further enhance fuel economy and emissions.
