Overall verdict
"The Mercedes GLA 250 e is like the Optimus Prime of the SUV world, seamlessly transforming itself from one type of a car to another depending what you need to do with it."

Okay, so the transformation isn't quite Transformers worthy in a visual sense – the 250 e doesn't start life as a truck before morphing into a towering battle robot with foot-long weaponry – but its powertrain does pull off a trick that's nearly as clever.
You see, the 250 e is a plug-in hybrid with a 37-mile all-electric range that makes it very cheap to run if you have a short commute and somewhere to charge it. It's quiet and relaxing to drive in town, will keep using its battery up to motorway speeds and provides ample acceleration as it gets there. Factor in that it's exempt from paying tariffs like the London Congestion Charge, and it's easy to see how the Mercedes could make sense if it fits your particular circumstances.
Need to go further? Well, that where the 'transforming' bit comes in because the Mercedes can seamlessly transfer to petrol power –calling on a 1.3-litre turbocharged petrol engine – to metamorphosis from frugal EV to a long-legged SUV that's great over distances. The combined might of the petrol engine and the electric motor produces 218PS and 450Nm of torque so the 250 e feels plenty quick and it's safe and reassuring to drive.
Being a Mercedes, it's also pretty blooming posh. GLA 250 e models dodge the lower rungs of the GLA range so they look smart on the outside and inside you get pretty infotainment screens, cool turbine-style air vents and leather on the seats as well as the insides of the doors. Meanwhile, the optional augmented reality sat-nav is genuinely mind-blowing.
Okay, so the design isn't quite as eye-catching as you get in the A-Class and sure, some plastics feel a bit cheap when you really start to poke around but relatively speaking, this is one of the poshest small SUVs on sale.
And it's also one of the most practical. A huge range of adjustment on the driver's seat means all shapes and sizes will get comfortable and even if you're a six-footer sitting upfront, people of a similar height won't feel squeezed sitting behind you.
The boot, meanwhile, is slightly smaller than you get in a regular GLA thanks to the batteries hidden under the floor, although you'd only notice if the cars were parked next to each other. The 250 e will happily swallow a set of suitcases and handle even bigger jobs with the rear seats folded away.
So, if during the week you need a car that can hum you to work in the city on cheap electricity before playing practical family wagon at the weekends – the 250 e could be the small SUV for you. It's no transformer, but it could have a transformative effect on the amount of money you spend commuting.
Is the Mercedes GLA 250 e right for you?
What other cars are similar to the Mercedes GLA 250 e?
Comfort and design
"The Mercedes GLA shares its underpinnings with the B-Class which is in turn a more practical version of the A-Class and this DNA courses through the cabin in the form of pretty turbine style vents and what looks like a huge one-piece glassy infotainment screen"

Trouble is, some of the magic of the A-Class has been lost in the GLA's SUV form. Its more upright exterior shape translates into vaster slabs of plastic in the interior and a design that's plainer and less sculpted than you'll find in the A-Class. That being said, this is still one of the prettiest interiors you'll find in an SUV this size.
The sports seats fitted to our car were comfortable, gave decent lateral support and also came with three-stage seat heating. If you want full electrical adjustment with lumbar support and a handy memory function – so the seat can glide back into your position after someone else has used it – you'll need to go for the range-topping Exclusive Edition Premium Plus model.

Handling and ride quality
"The Mercedes 250e GLA is an easy car to drive in any situation and its electric mode suits the Mercedes badge offering up silent running that's a perfect fit for the luxurious image."

Unlike a normal hybrid, which can only offer up a few miles of electric-only range and only under very light acceleration, the PHEV Mercedes will give you full-electric power most of the time so long as there's charge in the battery.
That means that in town you can easily potter about silently running on electricity if you leave the drive select in Comfort or Eco. As these sorts of speeds, the steering's light and the car's smooth automatic gearbox makes it easy to manoeuvre.
The Mercedes has decent visibility out all four corners of the car and reversing is helped by the large and deep rear window. You also get a reversing camera that beams by a high-def image from behind the car, while the GLA 250 e's standard Parking package adds front and rear parking sensors as well as auto park that can get you in and out of parallel and perpendicular spaces.
Leave the car in Comfort or Eco and the Mercedes can briskly accelerate up to the legal limit without needing to call on the extra power of its petrol engine, it's only when you stamp on the throttle that it will, after a bit of a pause, engage the combustion engine and fire you forward more urgently.
That said, select Sport in the drive select and the petrol engine's on all the time and the eight-speed dual-clutch automatic gearbox is primed – a couple of gears lower than usual – for sharp acceleration. It's not something you'll ever feel a great need to do though, because, in marked contrast to what you get in electric mode, the petrol engine sounds strained and thrashy under hard acceleration.
Steering that feels like it's connected to an elastic band (rather than the front wheels) doesn't exactly encourage hard cornering, but there's plenty of grip and not much body lean in bends. Meanwhile, the brakes are effective but sometimes tricky to use smoothly as the car bleeds in their regenerative effect to recharge its battery.
The GLA's more at home lolloping along on the motorway where the suspension, which sometimes hops in town, smooths out. Sure there's some tyre roar from the standard 19-inch wheels and noticeable wind noise, but this is a comfortable car to do long journeys.
Standard autonomous driving aids include active cruise control – that's a little too keen to (violently) return you to your preset cruising speed as quickly as it possibly can – and Lane Assist. The latter brakes opposing wheels to jolt the car back into the centre of the lane – effective, but a little unsophisticated next to more advanced systems that actually steer.

MPG and fuel costs
"More than any other type of car, how you use a plug-in hybrid like the Mercedes GLA 250e is critical to the kind of fuel economy you can expect it to return."

If you stick within the GLA's 37-mile electric range and have somewhere to charge it either using a wall box (1hr 45m minute charge time) or a three-pin plug (5hr 30m), you shouldn't ever have to burn any petrol – it'll cost pennies rather than pounds to run.
The beauty of having a plug-in hybrid is that you still have a petrol engine to fall back on for longer journeys and Mercedes quotes fuel economy of up to 202mpg – though you'll never get close to that on long drives in the real world. In fact, on long motorway trips, where the 250e is at its least efficient, you'll get better fuel economy out of an equivalent diesel.

How much should you be paying?
"The Mercedes GLA 250e is only just on sale, but there are already deals to be had by snapping up a secondhand example."

We've seen a 2020 Exclusive Edition model with 4,000 miles on the clock up for less than £35,000 – a £5000 saving on the list price of a brand new car, but perhaps more tempting was the same-age example with had covered just 150 miles going for £37,000. Be wary of cars further up the range which will be subject to a hefty annual road tax bill.
