First Test

As we say goodbye to our Mercedes-Benz E-Class long term test car we welcome its stable-mate, the C-Class, in C200 AMG Line Estate guise.

The C-Class is among Mercedes-Benz’s biggest selling UK model range, with the C220d being the most popular derivative among fleet customers.

A facelift towards the end of 2018, introduced a selection of new, more efficient diesel and petrol engines.

Our test vehicle is the 1.5-litre C200 petrol model with nine-speed automatic transmission and a manufacturer-claimed 44.1mpg fuel consumption figure.

 

It is fitted with optional extras including leather dashboard (£400), grey metallic paint (£685) and the Premium Plus package consisting of 64-colour ambient lighting, Comand online system with touchpad, LED lighting system, wireless charging, mid-range sound system and 12.3-inch digital instrument cluster.

It is equipped with a 48 volt ‘EQ Boost’ mild-hybrid system to help reduce fuel consumption, while improving performance and comfort characteristics.
 

When accelerating, EQ Boost will assist the 184PS engine with an additional 14PS, bridging the moment until the turbocharger has built up its full charge pressure which reduces turbo lag.

This power boost is also used to help the engine reach its ideal revs as quickly as possible during gearshifts.

During deceleration, the car recuperates kinetic energy and uses it to recharge the battery.

To further help improve fuel economy, the engine will turn off in certain situations when you lift off the accelerator, allowing the car to coast.

Fuel costs for the petrol model are an indicated 13.02ppm compared to 10.54ppm for the diesel which means over 80,000 miles, fuel costs for the petrol model would be £10,416 compared with £8,432 for the diesel.

However, the popular C220d has a £2,000 price premium over our test car.
