New Mercedes GLC 300 Coupe 2019 assessment
This, then, is the refreshed GLC Coupe. Revisions for the BMW X4 rival come similtaneously the remainder of the GLC household, and the modifications embrace refined styling tweaks, an overhauled engine line-up and Merc’s newest infotainment tech.
• New Mercedes GLC assessment
As with the normal 5 door GLC, the Coupe might be provided with a alternative of 220 d and 300 d – each 2.0-litre diesels – from launch. The 300 petrol we’re driving right here, will go on sale within the UK later this 12 months, powered by a brand new 2.0-litre four-cylinder unit. It’ll give Merc a singular promoting level over the established BMW, whose solely petrol choices are the extra highly effective X4 M40i and X4 M.
The brand new unit options delicate hybrid tech – a primary for the GLC. Generally known as ‘EQ Enhance’, the system consists of a 48-volt electrical system and a belt-driven starter/alternator. It’s a set-up that helps to scale back load (and subsequently gasoline utilization) on the engine in two methods. The primary is by recouping vitality when decelerating that may be redeployed beneath acceleration to minimise lag whereas the turbo spools up, and the second is thru a ‘gliding’ operate which might change the engine off for fuel-free coasting.
Different fuel-saving tech features a twin-scroll turbocharger and a brand new variable valve timing system, the latter of which will get the exhaust (and the particulate filter inside) as much as working temperature extra rapidly. The result’s 38.1mpg on the official WLTP testing cycle, and 169g/km on NEDC-adjusted calculations.
The mild-hybrid setup works very effectively in observe. Between the engine turning off an on once more, it hardly ever, if ever, feels caught out – firing up near-instantaneously with a press of the throttle pedal.
Elsewhere, the engine is a little bit of a combined bag. The engine isn’t significantly tuneful when pushed arduous, and whereas efficiency is robust – 0-62mph takes simply 6.2 seconds – it’s not sooner than the 300 d. The diesel unit affords up an additional 130Nm of torque, which makes it really feel far more vigorous in on a regular basis driving – and that’s earlier than both variant is totally loaded with folks and belongings, the place efficiency is prone to swing even additional within the diesel’s favour. Nevertheless, the usual nine-speed computerized gearbox is splendidly clean in on a regular basis driving.
The remainder of the driving expertise stays a lot the identical as earlier than. On the top-spec air suspension set-up, the GLC Coupe delivers a calming trip for essentially the most half, significantly in comparison with the far more firmly-sprung X4. Then again, the BMW feels sharper; even in sport mode, which drops the air springs by 15mm, the GLC doesn’t nook fairly as flat. It feels slower to show right into a nook, and in the end a bit of extra torpid.
So it doesn’t fairly really feel as sporty because the coupe tag suggests, and in comparison with sensible SUV alternate options, it does convey with it some drawbacks. That sloping roofline eats into rear headspace, whereas the boot is 80 litres smaller than the usual GLC’s. At 500 litres it’s nonetheless a roomy space – simply not that spectacular by SUV requirements.
From the driving force’s perspective, the cabin hasn’t modified a lot within the newest spherical of updates, however the tech put in actually has. All fashions get Mercedes’s newest MBUX infotainment system, which consists of a 10.25-inch show plonked on prime of the sprint. The inclusion of touchscreen performance does wonders for the usability, and mixed with a touchpad system first used on the A-Class, it means most customers will be capable of discover an enter methodology that’s snug for them.
Go for the elective Premium pack, and the usual analogue dials are changed with a 12.3-inch digital driver’s show. As on the primary infotainment display screen, the graphics look clear and sharp, and the driving force is ready to tweak the data proven through contact delicate pads on the steering wheel.
Costs for the Coupe begin from £44,045, which is £2,875 greater than the equal GLC SUV. The Coupe is accessible in AMG Line trim solely, however comes with three improve packages: Premium, Premium Plus and Final. As customary, there’s 19-inch wheels, sports activities suspension with adaptive dampers, and seats trimmed in a mixture of fake leather-based and suede-like upholstery.
The £3,500 Premium pack provides 20-inch wheels, multibeam LED headlights, leather-based seats and that upgraded driver’s show. Premium Plus introduces a Burmester sound system, a panoramic glass roof, keyless go and reminiscence seats, whereas the Final comes with air suspension. The Premium Plus provides £9,625 to the bottom worth of the AMG Line, and the Final is one other 4 grand on prime of that.
Whereas UK costs for the 300 petrol are nonetheless to be confirmed, it’s already accessible to order in Germany, the place it prices roughly €2,000 greater than the equal GLC 300 d. That’s so much for a four-cylinder SUV – irrespective of the way you have a look at it.
