Destined to become the crown in the new GLA line-up, the all-wheel-drive compact SUV uses the same turbocharged 2.0-litre engine as the A45 AMG and CLA45 AMG, meaning outputs of 355bhp and 332lb ft of torque.
The engine is mated to the AMG Speedshift DCT 7-speed transmission, which allows drivers to choose from three performance profiles named Manual, Sport and Controlled Efficiency. The latter mode is geared towards maximising fuel efficiency, and also activates the car's stop/start function.
The GLA45 AMG is due to go on sale in the spring alongside the standard GLA. The car has a claimed 0-62mph time of 4.8sec and its top speed is limited to 155mph. Combined economy is claimed to be 37.6mpg, while CO2 emissions are rated at 175g/km.
Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH, said: “Feedback on the Concept GLA 45 AMG during its world premiere at the Los Angeles Auto Show provided clear affirmation of our decision to bring this new AMG model to market."
Additional AMG modifications over a standard GLA include sports suspension, high-performance brakes, an AMG sports exhaust system and an exterior bodykit.
Bespoke interior trim on the car includes a performance steering wheel, performance leather seats and carbonfibre trim.
"Right now," added Moers, "no other segment is growing as rapidly as that of the compact SUV. Our new high-performance SUV offers not only the world’s most powerful series-production four-cylinder, but also impressively low consumption and emissions figures.
