There's something a little insane about getting handed a Mercedes-Benz GLK hybrid
for a SEMA
build and, instead of creating a lowered and overly-painted custom, trying to duplicate a Pike's Peak Unlimited Class rally racer. But it's that insanity that has always made RENNTech
one of the most entertaining tuning shops out there. Below we take the first look at the build and the specs for the RENNTech Rally GLK Hybrid
, debuting later this week.
About The Build With RENNTech's Jo A. Borras The Rally racer is obviously a bit lighter than the standard GLK, and makes use of high-performance components, including long-tube headers, composite airbox/intake, and RENNtech's own ECU software. We've added larger RENNtech brakes and a redesigned performance suspension system to help the GLK attack corners. Additionally, the hybrid drive should give an additional torque boost at the kind of low-speeds a rally car might find on a tight, demanding course. With the hybrid Rally car, we were trying to sharpen the car's reflexes and really give it a more aggressive, sporting look. Obviously this is not a car that is going to take on the unlimited class of 1000 hp cars, but it will be enough to be powerful and exciting - along the lines of a Subaru or Mitsubishi Evo - and it will accomplish that while being somewhat greener than the original version, which is the opposite of what people might expect. The public will very likely see THIS car, as we're trying to organize a few exhibition drives within the Formula D series. Without actually doing the tests, anything we would tell you would be dreaming. We're confident of a sub 6-second 0-60, putting the car into similar territory with the other rally replicas out there. Wheels are RENNtech's own lightweight 20" 3 pc. wheels in a matte finish - brakes are RENNtech's own recipe 16.2" front 2 pc. rotors with 8 piston calipers. Nitto is providing the tires. The rollcage will stiffen up the chassis to some degree, but the big change is the suspension itself, which has been replaced with a custom unit that allows adjustments in ride height, damping, camber, rake, etc. Most of the modifications [to the exterior] were made to fit the larger wheels and widen the track. The front splitter and rear diffuser, as well as lower side skirts, a very functional aerodynamically, and help direct airflow underneath the GLK with the goal of reducing overall drag and improving aerodynamic downforce. With the interior, we have eliminated most of the sound insulation and replaced the heavy Mercedes-Benz seats with much lighter carbon/kevlar buckets, which helped save some weight. We also did a full rollcage.
