The least costly Mercedes GLA, the GLA180, comes with the 1.6-litre petrol engine, Artico fake-leather upholstery, 18-inch wheels, and the equipment in all GLAs.
Spend more on a GLA-Class and you can have a diesel or a much more powerful petrol engine, as described above. You also get different exterior and interior trim, and more features.
Choosing the diesel GLA220d brings you dual-zone climate control, which lets you set different temperatures for each side of the cabin. You can unlock the car and drive away without taking the smart key from your bag or pocket – and a swing of your foot under the rear bumper opens the tailgate. Front seats have power-adjustable support for your lower back.
Choose a GLA250 4Matic and you also get heated front seats with full power adjustment, and a memory for your adjustments (so that you can restore your settings easily after a companion has driven the car). Headlamps dip automatically for oncoming traffic. And a large power-operated sunroof opens above front and rear occupants.
The GLA250 also brings you features aimed at improving its handling and roadholding. The most important of these are all-wheel drive (which adds grip when accelerating, and improves stability on slippery roads), and adaptive suspension (which can automatically soften the car’s ride over bumpy roads, and stiffen it for better control in fast cornering). Wheel diameter increases an inch, to 19 inches, and tyre profile shrinks slightly, marginally sharpening steering.
Additionally, an Off-road Engineering Package allows you to soften the accelerator response, and optimise the stability control, for very slippery or loose surfaces.
The Mercedes-AMG GLA 45 retains most GLA250 features but looks and feels sportier, inside and out, than the other GLA-Class cars. Equipment upgrades include leather seats, and a better audio system from Harman Kardon. There is also Distance Pilot Distronic, a more sophisticated driving assistance system that includes adaptive cruise control, high-speed auto-braking, and automatic control of speed in stop-start traffic.
The GLA 45 too is all-wheel drive and has adaptive suspension, but it rides on stiffer springs, for more responsive handling. Its 20-inch wheels carry tyres with a still lower profile. And because it is aimed unreservedly at high-performance road use, it does not have the off-road driving package.
Distance Pilot Distronic is available as an option on the three less costly GLA-Class cars, as part of a Driving Assistance Package that also brings you lane-keep assist.
