Efficiency is further boosted by a new heat pump, which is not only significantly more effective than the system in use today but also far more compact.
This has allowed Mercedes to integrate a 100-litre frunk in addition to a 560-litre rear boot, providing the GLC EV with even greater luggage space than the ICE GLC on sale today.
Additionally, Mercedes has developed a sophisticated new brake energy recuperation system, dubbed One Box. Unlike in traditional braking systems, the brake pedal is decoupled from the physical braking system, with computers calculating how much regen and how much physical disc should be used for the desired braking levels.
Dominik Voogdt, head of overall vehicle engineering for the GLC EV, describes this new braking system as a “game-changer” for overall efficiency.
The Galtispuoda Pass: a test of grit and grip
For my first drive of the GLC EV, Mercedes has brought me to the Galtispuoda mountain pass, just outside Arjeplog in Sweden’s Arctic north. This winding, snow-covered mountain road is a relentless test of a car’s mettle. It’s got it all: steep inclines, precipitous descents, fast open bends and sharp hairpins – all with surfaces that, at this time of year, shift unpredictably from compacted snow to sheer ice and back again before you realise.
With a heavy cloak of disguise covering the prototype’s dashboard and other areas, we can’t say much about the interior design yet, except that it departs quite radically from that of the ICE GLC models, which are likely to adopt it, along with a new pillar-to-pillar display panel and other digital developments, including the new MB.OS operating system, as part of a mid-life facelift before the end of next year.
That said, the driving position and ergonomics all feel familiar, with typical Mercedes refinement and attention to detail. A large glass roof floods the cabin with natural light, while a longer wheelbase than ICE GLC models (a benefit of the EV’s MB.EA platform) provides additional space, much of which has been allocated to extending rear-seat leg room. It’s very roomy, noticeably so in the back.
