Back in 2007, German autogiant, Mercedes-Benz, unveiled a concept future hybrid, the F700 research car, at the 2007 Frankfurt Motor Show. The F700 previews a future flagship Mercedes-Benz S-Class sedan.

The luxury touring sedan featured three regular opening doors and a fourth door capable of 180-degree rotation. The concept also featured bulletproof and puncture-resistant tyres.

The F700 is powered by Mercedes’ DiesOtto engine — so called because it combines elements of diesel and petrol (Otto cycle). It allows the F700 to reach 62 mph (100 kph) in 7.5 seconds and a limited Top speed of 124 mph (200 kph).
