In the four-door coupe kingdom, there are a handful of amazing vehicles; however, while it initially started off as a luxury endeavor, it has quickly morphed into high performance vehicles but now there's a new movement entering the fray.
That, my friends, is diesel power.
BMW, Mercedes-Benz and Porsche have all tossed their hats into this competition with their 6-Series Gran Coupe, CLS and Panamera but the question at the end of the day is simple: Who walks away with style, efficiency and a trophy to put in its cabinet?
In Auto Express' latest test, here are the results:1) Mercedes-Benz CLS350 CDI
2) BMW 640d Gran Coupe
3) Porsche Panamera DieselThe latest to join the pack is BMW. Its 6 Series Gran Coupe arrives this month, from £61,390. The four-door is essentially a stretched version of the 6 Series Coupe, and straddles the 5 Series and 7 Series line-ups in BMW’s busy range. It’s available with a pair of six-cylinder engines from launch, and here we test the £63,900 640d SE.
Having started the four-door premium coupe sector all that time ago, the CLS has the advantage of being one step ahead of the competition. It’s now in its second generation, and offers head-turning looks, a broad engine range and sharper dynamics than its predecessor. We’ve chosen the mid-range CLS 350 CDI Sport, priced at £54,210.
Completing our test trio is the Porsche Panamera. It sets the standard for driving thrills in this class, plus in £62,134 diesel guise it should be affordable to run.
