BMW states its Mercedes-Benz S Class rival has been engineered from the ground-up. It weighs 130kg lighter than the previous generation 7 Series and features the German car manufacturer's latest touchscreen i-Drive infotainment system and a new driving mode, called 'Comfort Plus'.
The production model will be unveiled at September's Frankfurt motor show, but you can read our verdict on the BMW 740iL prototype here.
3 - Mercedes-AMG GT S Edition 1
It's not difficult to understand why the new Mercedes-AMG GT S has ranked so highly with readers this week. With those hulking looks and powered by the German car firm's latest 4.0-litre turbocharged V8 motor - pumping out 503bhp and 479lb ft of torque in this state of tune - it's sure to give any Porsche 911 owner food for thought.
Built exclusively by Mercedes-AMG - the performance arm of Mercedes-Benz - the GT S is the replacement for the gullwing-doored SLS.

4 - Audi RS3 Sportback
Audi's rapid RS3 in 'Sportback' guise has proved a huge hit with Autocar's online contingent since we tested it more than a week ago.
With a tweaked 2.5-litre five-pot turbocharged motor now developing 362bhp and enabling the new RS3 Sportback to hit 0-62mph in 4.3sec, it's a worthy alternative to Volkswagen's new Golf R Estate.

Now the Estate version is continuing the popular trend and features on our list for the first time. Click here to read our review of the fast family wagon.
