The BMW 7 Series is a line of full-size luxury vehicles produced by the German automaker BMW. Introduced in 1977, it is BMW's flagship car and is only available as a sedan or extended-length limousine. The 7 Series traditionally introduces technologies and an exterior design theme before they trickle down to smaller sedans in BMW's lineup
In America, the models were sold as the 740i, 740iL and 750iL. The 740i and 740iL shared the same 4.0 L V8 engine in model year 1995, but the next year the V8 grew to 4.4L while stated power stayed at 282 hp (210 kW), though torque grew from 295 to 310 lb·ft (400 to 420 N·m). The considerably rarer 5.4 L V12-powered 750iL was only available as a long-body; there was no E38 750i in the US lineup.
The 2011 ActiveHybrid 7 is a mild hybrid and features a 0.4 kWh lithium-ion battery pack.The electric motor is combined with BMW’s 4.4-liter twin-turbo V8 and new 8-speed automatic transmission to accelerate from 0 – 60 mph in just 4.7 seconds. Estimated EPA fuel economy is 17 miles per US gallon city and 26 miles per US gallon (9 L/100 km; 31 mpg-imp) for highway, which represents almost an 18% improvement over the non-hybrid 750i/Li.
