In the petrol corner is the latest GLC 300 coupe with its turbocharged four-cylinder petrol engine boosted by a 48-volt starter-generator, which earns it the EQ Boost badge. The powertrain sends 258hp to all four-wheels via a nine-speed automatic transmission and in well-equipped AMG Line Premium form as shown here it costs just over £52,000.
Up against it is the first of Mercedes’ EQ breed of all-electric machines, the EQC. It is built on a version of the same underpinnings as the GLC on the same production line, is clothed with a body that’s almost as coupe-esque, and is powered by motors on both front and back axles. It’s equally all-wheel-drive as the GLC then but with just a single-speed, direct-drive transmission. With all its torque one gear is all you need.
In fact it has double the torque of the petrol GLC, as well as 150 more horses under the bonnet. Underpowered the electric newcomer is not, but it needs the extra because it weighs close to 700kg (about the weight of eight people) more than its petrol counterpart. The EQC’s lithium-ion batteries account for the vast majority of this lardiness.
The EQC is a heavyweight in the price stakes, too. Prices start at £65,000 but the car you see here in AMG Line Premium Plus form costs over £73,000, even after the government has knocked £3,500 off with its electric car grant. In truth it’s about what the EQC’s premium electric rivals, such as the Jaguar I-Pace and Audi e-tron, cost, but it’s still leaves the petrol car with a £20k advantage, though it would of course be easy to lose that by up-speccing your GLC with an AMG badge. Alas down-speccing the EQC to a more affordable entry point is not likely any time soon.
