CY Foong · Aug 18, 2020 11:00 AM

Not to be outmatched by Volkswagen, BMW too have launched four brand new models at a launch last week. There was the X4 M Competition which is an absolute beast that can reach 100 km/h from rest in 4.1 seconds, the exquisite and expensive M8 Coupe and Gran Coupe, and finally our star, the X3 M Competition.

The BMW X3 M Competition is the Bavarian’s latest performance SUV, competing against the Mercedes-AMG GLC 63 and the Porsche Macan. But we’re going to focus this battle as a 2-way battle between the two eternal rivals, so sorry you’re not invited for this round, Porsche.

Prices shown are valid until 31 December 2020

Let’s start this short and quick comparison with the price. Both the X3 M Competition and GLC 63 are fully imported and are priced very closely. The X3 M Competition starts at RM 886,551 while the GLC 63 S starts at RM 884,542. Both prices are on-the-road excluding insurance and are exempted from SST which is valid until 31 December 2020.

The GLC 63 S is RM 2,009 cheaper than the X3 M Competition but interestingly both SUVs have the same horsepower – 510 PS. That lower price is probably due to the local GLC 63 S being a pre-facelift model.

But that’s where the similarities end. The engine size for the X3 M Competition is smaller than the GLC 63 S – a 3.0-litre twin-turbocharged S58 straight-six engine compared to a 4.0-litre twin-turbocharged M177 V8.

Both SUVs are all-wheel drive but the GLC 63 S trumps the X3 M Competition in both torque (700 Nm to 600 Nm) and the number of gears (9-speed to 8-speed).

Then there are the numbers that matter in a performance SUV. The X3 M Competition does 0-100 km/h in 4.1 seconds and top speed is limited to 250 km/h. Meanwhile, the quicker and slightly cheaper GLC 63 S does the century sprint from rest in 3.8 seconds and top speed is limited to 270 km/h.

Both German performance SUVs are adequately packed with features. Well, if you are paying nearly a million ringgit for a car, you’ve got to expect the best.

In terms of infotainment, the X3 M Competition comes equipped with a larger 10.25-inch screen with Apple CarPlay and Android Auto support. It even comes with Harmon Kardon surround sound system which is connected to 16 speakers.

The GLC 63 S on the other hand has an 8.4-inch touchscreen set-up with Burmester surround system connected to 13 speakers.

The BMW has M badges all around the interior

Safety-wise, both performance SUVs come with ADAS including autonomous braking, front collision warning, active cruise control, lane-departure warning, and a 360-degree camera.

What it comes down to in the end is whether you’re into Beemers or Mercs. Both the X3 M Competition and GLC 63 S are very similar in price and very similar in power output.

The GLC 63 S has a very stately and exclusive aura around it – fitting of the three-star badge. The X3 M Competition on the other hand, gives off a performance vibe even though it loses out to the GLC 63 S on paper.
