Rising oil prices and tougher fuel-economy requirements are the inspiration for the latest wave of fuel-saving vehicles. Prominent among them are more small cars, gas-electric hybrids, and electric cars. However, many larger mainstream vehicles are being tweaked to improve their gas mileage by more conventional means, such as innovations in turbocharging, weight reduction, aerodynamics, and direct fuel injection.
Moreover, even the least expensive cars will have improved safety features, because federal laws now require antilock brakes and electronic stability control as standard equipment on all cars and light trucks. And backup cameras are becoming common, especially on SUVs, where they’re often needed the most.
2012 Audi A6
The A6 redesign features lighter aluminum body panels and a direct-injection 310-hp 3.0-liter V6 mated to an eight-speed automatic transmission to help improve fuel economy. The base engine is a turbocharged 2.0-liter four-cylinder good for 211 hp paired with a CVT. The front wheels have been moved farther forward, allowing for more cabin room, and the MMI driver-interaction system is said to be a bit easier to operate. Available gadgets include a color heads-up display, a night-vision display, and LED headlights.
