…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.

…ThinkGeek makes the best flying saucer?

Micro R/C Flying Saucer

ThinkGeek’s Black Stealth 3-Channel R/C Helicopter is a fun way to start flying, but if you really want to be in control, then check out their Micro R/C 4-Channel Flying Saucer.

Described as “the smallest, most sophisticated R/C flying vehicle around”, it gives you control over altitude, direction and rotation, and features a solid-state accelerometer that senses tilt on two axes and adjusts the power of each propeller to keep the Flying Saucer rock solid in the sky.

In addition, a built in automatic trim means no trim dials or buttons to adjust, so you just power-cycle the remote before you begin to fly, and the Flying Saucer references the accelerometer to auto trim itself.

Nifty!

…It’s Tuner Tuesday: WhiteKnightTwo?

WhiteKnightTwo

Sir Richard Branson and Virgin Galactic continued their quest to turn space into a tourist destination on Monday with the roll out of the new WhiteKnightTwo (WK2) carrier aircraft that will ferry SpaceShipTwo and “thousands of private astronauts, science packages and payload on the first stage of the Virgin Galactic sub-orbital space experience”.

WK2 is the world’s largest all carbon composite aircraft, and at 140 ft., the wing spar is also the longest single carbon composite aviation component ever manufactured.

Powered by four Pratt and Whitney PW308A engines, WK2 will support up to four daily space flights, and reach a maximum altitude of over 50,000 ft (limited only by the atmosphere).

It might only be for the rich and famous right now, but soon, Virgin Galactic hopes that you’ll hop aboard SpaceShipTwo, and WhiteKnightTwo will whisk you away into the blackness of space for a quick lap around the Earth.
