But America's infrastructure and culture is heavily biased toward the personal automobile and the need to make road trips, even if few drive more than 100 miles a day.

But even if we can't get to a full battery EV fleet any time soon, there's still plenty of low-hanging fruit.

That car is no longer available, but the company's next PHEV push will be spearheaded by the Q5 TFSI e SUV—the e-tron name now being exclusive to Audi BEVs.

The Q5 TFSI e uses a parallel hybrid powertrain with a 2.0L turbocharged direct-injection gasoline (TFSI) engine and an electric motor that work in concert to send torque to all four wheels via a seven-speed dual-clutch (S-tronic in Audi lingo) transmission.

The electric motor is fed by a 14.1kWh lithium-ion battery that provides 25 miles (40km) of electric range under the European WLTP test cycle—the EPA has yet to rate the US-spec PHEV, which will also do without the car's ability to coast at cruising speed.

The A7 TFSI e gets the exact same powertrain as the Q5 TFSI e, but the larger, heavier A8 is slightly different.
