Mercedes-AMG E53 Hybrid 4Matic+

There's no new E63 for now, but there is a new E-class range-topper, and it's AMG's first long-distance PHEV

- JAMES TAYLOR

MERCEDES-AMG IS NOT PLANNING TO Mbuild a new E63. So, for the foreseeable future, this is the most potent E-class you can get: the new E53 Hybrid 4Matic+. Available as either a saloon or estate, it's AMG's first 'long-range' hybrid, a plug-in with a 59-mile all-electric potential.

A 120kW electric motor is integrated into the transmission between the engine (a 443bhp 3-litre straight-six) and gearbox (a nine-speed auto). Total system output is 577bhp and 553lb ft, although Race Start mode - included in the optional AMG Dynamic Plus package - gives you a 604bhp total output, albeit only momentarily from a standing start. The 400V, 28.6kWh battery lives under the boot floor, meaning a slightly smaller boot than in other E-class variants, though still a reasonably roomy one.

It's not the same powertrain as that found in the similarly named Mercedes-AMG CLE 53 hybrid (see Driven, evo 322): the engine is virtually the same but the hybrid side of the equation is rather different, as the CLE 53 isn't a plug-in.

The E53 can travel at 87mph powered by its electric motor alone. As a default, unless you change the drive mode before setting off, the car pulls away in electric 'EL' mode, using its electric motor only. (After all, it can deliver its 354lb ft from effectively Orpm.) If you need more power, or the battery's running low, it automatically-and smoothly, it must be said - brings the engine into play and switches to Comfort mode.
