BMW’s 7-Series is back, and it’s aiming to set a new benchmark for luxury models. With a fresh look and toned down rear end, the car takes a more subtle approach.

However, don’t be fooled by the modest lines of the exterior, because this latest executive quickly proves it has what it takes to be leagues ahead of most rivals.

Never mind luxury – fuel economy and emissions are at the top of the class, too. Average consumption of 39.2mpg is good, particularly when you consider that the BMW weighs 1,865kg. You’re likely to see even better figures when the limo is in its natural motorway habitat, because it cruises at a hushed 1,700rpm at 70mph.

This efficiency is unlikely to deteriorate when you floor the throttle, either. The diesel-powered 730d delivers 242bhp, and is still faster than rivals such as the Audi A8 3.0 TDI and Mercedes S320 CDI.
