MBTech takes CNG Mercedes Benz SLK Concept to the Nurburgring

[keltanky]

In an attempt to show off the potential of Compressed Natural Gas (CNG) cars, MBTech, an engineering group with close ties to Mercedes Benz, has run a series of tests at Germany’s Nurburgring using a SLK powered by the alternative fuel. The aim was to show that reduced CO2 emissions don’t have to mean lower performance.

MBTech also used the cramped trunk of the SLK, which still has to store the car’s folding roof, to showcase its new compact gas cylinder design. Other new technologies featured on the CNG SLK concept included new fuel-injection and exhaust system.

The CNG SLK Concept from MBtech develops up to 196hp (146kW) and a maximum torque of 200lb-ft (270Nm) from its 2.0L four-cylinder engine. This is enough to accelerate the car from a standstill to 100 km/h in a respectable 7.8 seconds. It has a top speed of 244 km/h.

While this is nothing to get excited about, it requires only 5.6kg of CNG per 100km and emits less than 150g of CO2 per km, which is still impressive for the amount of performance delivered.

The key to the design of MBTech’s new CNG system is a fifth injector, which is used to enhance the traditional four injection valves. However, this does not inject the gas selectively into the cylinders but rather into the central air intake. This enables the delivery of the quantities of gas required for the high cylinder performance even in the event of strongly fluctuating gas quality.

MBTech is yet to reveal if any major carmakers are planning CNG versions of their top sports cars but given the need for more fuel-efficient models in most markets we could see some of the technologies demonstrated in the CNG SLK Concept make their way to production in the near future.

not bad the rims on the slk...

[Guest ACSLK]

yes the rims is not bad i think either is Volks, Rays or OZ rims...........White car with black rims (not bad)........

You forgot the power also not bad man:

looks OZ rims to me....

hm... can consider.... :devil2:

[Guest ACSLK]

i always love to have Volks, Rays or OZ rims but not sure will it looks good on SLK....(Black car with black rims)....also i like the overall 1 brand look/feel...eg if AMG then all AMG better.....not really like to mix and match.....(just my opinion but i could be wrong) nice can already right?

Cheers......

I have a soft spot for the TE-37 6 spoke classic. Bronze rims on black car would be quite swee too.

Copied from an mbworld.org thread. These were made to fit an Audi but I reckon with spacers, it should be able to fit Mercs as well.

Quick photoshop job!

Nice man......specially with those red BBK....... :clap:

[Guest ladyseals80]

hm...

TE-37 the rims are nice.... but i still like the one kelvin posted.

always wanted black SLK with black rims...

think i may get a 17" juz for track use lolz...

see how...
