Sixth-generation executive saloon and estate ramp up the luxury and tech The new car market is changing faster than ever, but that doesn't mean some things can't say the same - and the Mercedes E-Class is a case in point. Despite years of progress, the big German's underlying receipe of quality, comfort, space and refinement remains largely untouched. This then is new ‘W214’ E-Class, which is the latest iteration of one of the oldest model lines from one of the oldest car manufacturers. By Mercedes-Benz’s own count, it is the 10th generation of a largely unbroken lineage going back to 1947.Despite being very keen to refer to its heritage (and why wouldn’t it be?), Mercedes isn’t a particularly nostalgic company. It has come up with radical designs, such as the original A-Class and Smart City Coupé, while its electric cars are really exploiting the aerodynamics and design possibilities that an EV offers. Unlike with the BMW i5 and 5 Series, Mercedes is choosing to keep the electric Mercedes EQE and combustion-engined E-Class apart. According to the literature, the new E-Class needs to balance tradition with modernity and ‘build a bridge’ between traditional exec saloons and the tech-filled EVs of the future. Plenty of buyers are not ready for their car to be a smartphone on wheels, so that mission could well strike a chord. To find out whether the E-Class might succeed, we've road tested an E220d saloon, though we've also driven the E300e and both the E220d and E450d EstatesThe range at a glanceModelsPowerE200201bhpE220d194bhpE300e308bhpE300de308bhpE450d 4Matic362bhpMercedes-AMG E53 Hybrid 4Matic+577bhpThe E-Class offers a very wide range of powertrains, including a four-cylinder petrol, diesel and plug-in hybrid, a six-cylinder diesel with four-wheel drive and uniquely for Mercedes, a diesel plug-in hybrid. Topping the range for the time being is the E53 AMG, with a plug-in hybrid six-cylinder. In other regions, there's an E450 petrol as well, but that is not offered in the UK for the time being - and is unlikely to make an appearance over here anytime soon.Apart from the top-rung Exclusive Edition, all trim levels are all AMG Line of some sort, with Advanced, Premium and Premium Plus packs tacked on for the more expensive versions.
