…The Lamborghini Murcielago LP 670-4 SuperVeloce is perfection?

When Lamborghini decides to build a car like the Murcielago LP 670-4 SuperVeloce, you don’t ask questions, you just say thank you and quietly pick your jaw up off the floor.

Lamborghini themselves even describe this car as “exceptionally purist”, and I can’t find any reason to disagree. The 670 indicates a horsepower jump from the already potent LP 640 to 670 hp and 487 lb-ft of torque out of the 6.5L V12. Extra power wasn’t the only thing Lamborghini managed to squeeze out of the package though, as more than 220 lbs of weight savings have occurred, leaving the car with a 0-62 time of just 3.2 seconds and a top speed of 212 mph. However, if you opt for the larger “Aeropack Wing”, the added downforce will limit you to only 209 mph.

Minor, yet still stunning details include a new engine cover with three hexagonal, transparent polymer plates supported by a carbon fiber framework, and an interior that is upholstered entirely in Alcantara with stitching that matches the exterior color of the car. Finally, the fighter pilot theme is carried over from the Reventon, with landing strip accents on the seats and floor panels.

The Lamborghini Murcielago LP 670-4 SuperVeloce isn’t a car that anyone needs, but when it takes an entire breath of air to say the very large and very Italian name, and each word sounds faster than the next, you know it’s a car that almost everyone is going to want.

…It’s Tuner Tuesday: RENNtech Pikes Peak Rally Racer GLK?

RENNtech Pikes Peak Rally Racer

Every year, SEMA serves as the debut for some of the most outrageous cars and stunning concepts from tuners around the world, and this year, Mercedes-Benz decided to get in on the action with the debut of their new GLK.

One of those GLKs that stormed the SEMA show is this Pikes Peak Rally Racer from RENNtech, and with its inspiration coming from the winged, unlimited-class rally cars of the famed Pikes Peak Hill Climb, it’s no surprise that the styling needed to be kicked up a few notches.

However, beneath the menacing exterior lies a powertrain that might surprise a few people: a hybrid, designed to make the GLK a formidable performer while at work and at play.

By combining an electric motor in parallel with the 3.5 liter V6 petrol engine, RENNtech has been able to capture the impressive torque that characterizes electric motor drives, adding 54 Nm to enhance the GLK’s performance off-the-line and out of corners.

In addition, internal combustion engines can start to wheeze as the ambient air thins at the higher altitudes that a hill climb takes place in, but with a hybrid drive, thrust is maintained at any altitude with help from the electric motor, allowing the GLK to remain strong during every part of the race.

The 3.5-liter V6 engine that comes stock in the GLK received a special intake manifold, cams and cylinder heads directly from MB, and then RENNtech added their own long-tube headers, composite air intake, and RENNtech ECU software to make the engine put out approximately 350 horsepower on gas power alone.

To help with speed, RENNtech cut weight by removing most of the sound insulation and replacing the Mercedes-Benz seats with lightweight carbon-fiber buckets. With the addition of a full roll cage and the movement of several components towards the rear of the GLK, weight distribution almost reached the perfect 50/50, which helps handling on tight, demanding rally stages.

Custom coil-over suspension was created by KW for RENNtech, allowing for adjustments in height, rake, damping rate, camber and toe-in, and 412mm, 2-piece rotors with 8-piston callipers from RENNtech handle stopping power in the front, while 4-pot callipers grab 356mm discs in the rear.

Not so subtle exterior modifications include a front splitter, rear diffuser, and lower side skirts all designed to help direct airflow underneath the GLK to reduce drag and produce added downforce, while improving high speed stability at the rear. The rear wing elements also serve an important aerodynamic purpose, and flared wheel arches and other bodyshell modifications “create a powerful side line that highlights the dynamic thrust of the Rally Racer”.

It’s definitely not the subtlest Mercedes-Benz on the road, but if you want cutting edge, rally ready technology that’s designed to get you where you want to go at a very high rate of speed, then look no further than the RENNtech Pikes Peak Rally Racer.
