2017 Mercedes-Benz GLC300 4Matic Long-Term Update 1: Learning Curve

Post a Comment

Our long-term 2017 Mercedes-Benz GLC300 4Matic has been with us for a few months now and although things have gone smoothly, there’s been a light learning curve as I get used to daily driving our metallic brown 2017 SUV of the Year. The GLC300, it seems, drives differently—more efficiently—than many small luxury crossovers and SUVs.

The issue is largely a personal one, but it’s something I’ve grappled with as I go off to test drive other cars for a few weeks at a time and get back into the GLC,  and it’s something I suspect many new GLC buyers will deal with as they get used to their new cars.

The trouble, I think, is that the GLC is tuned too correctly.

Hear me out. What happens when you get off the gas when you’re driving your gas-powered car? You probably start noticeably slowing down as you coast.  In other words, you’re getting a small but obvious amount of engine braking from your car.

You don’t really get that in the GLC. Get off the gas as you approach a stop light or traffic, and the Mercedes doesn’t seem to naturally slow down—instead it coasts along for about four Mississippi before finally beginning to shed speed.  From an engineering perspective, this trait probably is exactly what Mercedes’ engineers intended from the GLC’s 2.0-liter turbo I-4 and nine-speed automatic (not to mention low-rolling resistance tires) as it’s wasting as little kinetic energy as mechanically possible.

It still takes a few getting used to, even though?Particularly since it approach I?M urgent a lot more difficult on the brakes than I might in any other case to avoid rear-ending a fellow motorists.

I desired to test my theory so whilst I turned into overseas on mission I passed the keys to the GLC off for a few gas economy testing. On the EPA?S fuel economic system test, our all-wheel-power equipped GLC300 is rated at 21/28/24 mpg town/motorway/mixed. We sought to duplicate the EPA?S consequences with our very very own Emissions Analytics crew and netted a Real MPG of nineteen.2/29.3/22.7. That?S an eight.6 percent dip on the metropolis cycle, four.6 percent growth at the dual carriageway cycle, and an typical drop of 5.4 percentage at the mixed cycle. Looks just like the numbers don?T always returned up my theory, however it?S well worth noting that our Real MPG checks are all done beneath a car?S default power program, which inside the GLC300?S case is Comfort mode. We?Ll check the GLC once more at a later day in Eco mode, which makes use of tricks which include automatically setting the transmission into neutral even as coasting to eke every remaining mile from every gallon of gasoline.

In the intervening time, I?Ve spent the last few weeks street tripping our Mercedes GLC300 4Matic up and down California, and I suppose it?S secure to mention I?M finally getting used to its unique driving quirks.
