Bloody hell it's fast. On the launch a couple of cars felt slightly under the weather; no such problems here. Remember the GLA is only 30kg heavier than an A-Class, a car that has been timed to 100mph in 10 seconds. The optional AMG addenda may look a bit extravagant but it's certainly not making false promises. Conventional AMG owners beware: these four-cylinder cars don't want for any performance.
A big dump
Moreover, the 2.0-litre is a fabulous engine. When discussing most modern turbos, it's a case of a huge torque dump before 2,000rpm with no real incentive to rev it. Fast and easy, yes, but not the most exciting. The Mercedes is very different. There's a bit of lag and plenty of low-rev torque too but a second wind at about 5,500rpm that still comes as something of a shock. It's properly ferocious round to the limiter, revving with an intensity you would never credit such a heavily turbocharged engine with. Indeed upshifts can occasionally be missed (it's not always the gearbox...) as the engine convinces you it has another 1,000rpm or so left to run. A Black Series going beyond 7,000rpm would be something to savour.
If the old AMG V8 bruisers need to be mindful of the new breed in a straight line then they don't stand a chance around corners. Yes, even the GLA45. As with the A and CLA, it's the tautness and the precision of the damping that shines through, the body's resolute control giving the confidence to attack bends faster and faster. The brakes are stellar too, with exemplary feel and performance. There can't be much faster down a British B-road. Perhaps not the conventional AMG skillset but a thrilling one nonetheless.
What a shame then that the Haldex-derived four-wheel drive just isn't as crisp as the rest of the dynamic package. Only very seldom does the GLA feel anything other than a very capable front-wheel drive car. Attempt to neutralise it with a lift or more power results in a lot more push before any power is distributed rearwards. On occasion there's that sensation of all four wheels powering you out of a corner but it requires too much commitment on the road.
C-Classand AMG GT. Perhaps that's a shallow observation but if you're spending £50K on a car it needs to make you smile during the dull drives as well as the pants-on-fire journeys. On seeing a new C-Class cabin the GLA45 may not do that.
And no, that £50K isn't a misprint. In fact KP14 CJZ had a list price of £53,080 through options such as an AMG Aerodynamic Package and, er, AMG Night Package. Mercedes insiders tell us this is in fact a typical options spend for many '45 buyers so the prospect of most equivalent GLAs leaving with a price in the 50s isn't unrealistic. Wow. The GLA is an endearingly daft though, and anyone who dismisses it on styling or a perceived engine deficit must drive it. It really is very good. However, it's hard to escape the feeling that most customers would be better served by a regular A45 hatch or the upcoming Shooting Brake.
