The A-class has very clear sporting intent, from its stunning looks to the way the chassis and suspension deliver really sharp handling. It’s also got lots of stylish appeal, able to make jaws drop more easily than most big SUVs when it drives by. This is a car that speaks to your emotions, so how does it fare when teamed up with a little practicality in the form of a diesel engine? We drove the A 180 petrol last month, and its weakest point was undoubtedly the motor under the hood. This A 180 CDI version, on paper at least, looks promising. But can it deliver where the petrol could not?
For a start, forget the ‘180’ badge; this engine actually displaces 2143cc and is essentially a version of the same OM651 motor we’ve seen under the hoods of the C-class, E-class and M-class, in 220 CDI and 250 CDI forms. It’s been modified for front-wheel drive and transverse mounting under the hood of the A-class (and indeed the B-class), and detuned to produce 107bhp and 25.5kgm of torque.
Twist the key and the engine thrums to life, and at idle, it’s all but silent with only minor vibrations. Thanks mostly to the big engine, the diesel A-class weighs a chunky 1505kg – that’s a full 110kg more than the petrol. As a result, the 0-100kph dash takes a relaxed yet brisk 11.29sec. However, the readily available torque from the high-displacement engine sort of makes up for it. Power delivery is pretty linear and you can barely feel the turbo kicking in. There’s a gentle surge at around 1500rpm, followed by a strong thrust till about 4000rpm. Things become a bit vocal near the redline though, so it’s best to work with the motor in its meaty midrange.
Merc’s 7G-DCT double-clutch gearbox makes clever use of its seven speeds to respond well to those part-throttle inputs that are an integral part of driving in traffic. It shifts smoothly and the engine is quiet at city speeds as well. You can always put it in Sport or Manual mode for urgent overtaking or when you want to have fun behind the wheel. The 20-80kph is done with in 7.03sec, while 40-100kph goes by in 9.14sec.
You’ll love the A-class on a winding road. With the stiff suspension and wide 225-section tyres, the baby Benz changes direction willingly and there is loads of grip. This, combined with superb body control, means you can scythe through a series of bends with complete confidence. Straight-line stability at highway speeds is terrific too, and the A-class is very reassuring to drive. The steering, although not very consistent in the way it weighs up, is direct and helps you place the nose accurately where you want to. But the A-class’s biggest weakness is undoubtedly its hard low-speed ride; you can feel every little road disturbance. The standard low-profile 225/45 R17 tyres are the main culprits here. But the ride improves considerably as you go faster, and the Merc feels more pliant. Also, the low stance and long wheelbase mean you have to tackle large speedbreakers with utmost caution. Though we didn’t scrape the underbelly during our tests, it’s easy to do so.
A quick word on the styling – because the pictures really speak for themselves with this car. The CDI is available only in a lower ‘Style’ trim, as opposed to the petrol which is only available in ‘Sport’. As a result, it loses the big panoramic sunroof and the exotic diamond-effect grille is optional; but that’s about it.
If there’s one thing that cements the A-class’s credentials as a seriously luxurious product, it’s the quality of the interiors; after all, if it doesn’t make you feel privileged, what’s the point? Every surface feels properly premium – the soft-touch dashboard front, the beautifully finished, SLS-style air-con vents and the perfectly damped buttons on the steering wheel, to name a few. This may be an all-black cabin, but there is enough metallic brightwork in here to liven things up. The 5.8-inch COMAND screen ‘floats’ above the air-con vents, but isn’t big enough to be distracting when you’re driving. Because the gear selector is on the steering column, the central tunnel has been used for cup holders and cubbyholes; but they aren’t very big.
This is a car designed around the driver rather than the passengers, and it really shows. The front seats, with their snug, single-piece backrests, are a great place to spend time. They’re comfortable and supportive, and the driver’s side has full electric adjustment. The only downside is the visibility which, thanks to the sharply angled windscreen, low seating position and small glass area, is quite poor. The focus on the driver is even more apparent from the back seat, though. You have to duck under the curved window line to get in, and then you’re greeted to an upright bench that’s designed for two; there’s a third seat belt, but not much room to sit. There are no rear AC vents, the windows are tiny, and the big, curvaceous front seats are right in your face. Although the legroom is decent, the headroom is tight, and the combination of a low seat and short squab means you’re forced into a knees-up seating position.
It is equipped like a Mercedes though, with a big focus on safety tech. There’s no less than nine airbags in this little cabin, and a host of active and passive electronic aids. On the infotainment front, Merc’s dated COMAND system soldiers on; it’s not as intuitive to use as its more evolved competitors, but it gets the job done. There’s Bluetooth, Aux and USB connectivity here and most of it can be controlled from the buttons on the steering wheel. Surprisingly, in such an expensive car, there’s no climate control.
