BMW 7 series
The BMW 7 Series is a full-size luxury sedan produced by the German automaker BMW since 1977. It is the successor to the BMW E3 "New Six" sedan and is currently in its sixth generation. The 7 Series is BMW's flagship car and is only available as a sedan or extended-length limousine. It traditionally introduces technologies and exterior design themes before they trickle down to smaller sedans in BMW's lineup. The first generation 7 Series was powered by straight-6 petrol engines, and following generations have been powered by straight-6, v8 and v12 engines with both natural aspiration and turbocharging. Since 1995, diesel engines have been included in the 7 Series range.
