A prototype BMW 7-Series Hybrid was spotted consorting close to the Nürburgring’s Nordschleife. Prospective buyers will have to wait till the year end when they can get a hold of their 7 Hybrids. This is a key car for BMW since it will seal the same place in the US that extravagance diesels take up in Europe.

Its ActiveHybrid system will be shared with an X6 Hybrid. But at the same time there will be a lot of differences in architecture of the two systems so that it matches these two different cars. At the center is a 4.4-litre twin turbo V8 motor which will run together with an electric unit that establishes 20hp (15kW) and 210Nm of torque. When this is merged with the petrol V8′s 400hp (294kW) and 610Nm of torsion then the outcome is a 420hp (309kW), 820Nm hybrid super limo. A revitalised braking system will be applied and this helps in cutting fuel consumption by 15%.
