A range of four-cylinder petrol and diesel engines are offered in the Mercedes-Benz GLA. The entry-level GLA 200 gets a 154bhp 1.6-litre turbocharged petrol, while the GLA 200 and 220 CDI pack a 2.1-litre turbodiesel in 134bhp and 168bhp guises.
A more powerful petrol option, badged the GLA 250, features a 208bhp 2.0-litre turbocharged engine. All are available with Mercedes' 4Matic four-wheel-drive system, which grants buyers the further option of a dual-clutch seven-speed automatic transmission. Front-wheel-drive models otherwise get a six-speed manual transmission.
We've yet to test the entry-level GLA 200, but have sampled the flagship GLA 250. It offers up a substantial amount of torque, granting the GLA stout performance. It's a clean and economical choice too, with Mercedes claiming an average 42.8mpg and CO2 emissions of 154g/km.
Most buyers are likely to default to the diesel options, however. Although it doesn’t seem the most modern turbodiesel on the market, Daimler’s 2.1-litre lump does lend the GLA a fairly authoritative level of performance befitting a premium product.
