777 HP RENNTECH SLR: The HP War IS NOT Over


AMG boss Volker Mornhinweg recently repeated what he said a year ago by declaring that the horsepower war was indeed over. The last time he said it the Mercedes tuning experts at RENNTECH countered by announcing a 695 hp package for the 65 Series cars. This time they're making their point even stronger by releasing a 777hp version of the iconic SLR.

That's right… 777hp!

There is more of a story behind the RENNTECH 777 than that, however. The supercar has actually been planned for quite a while and is the first of several special edition vehicles RENNTECH will release in 2009 to celebrate the company's 20th anniversary.

In order to get all that extra power - an addition of 160hp over the standard model - RENNTECH modified both the supercharger as well as the engine's internals. Also key in the build was an upgraded cooling system.

With all that extra power RENNTECH engineers also reinforced the transmission and installed a new limited slip differential built by Japanese supplier OS Giken. The new diff can send up to 100 percent of the power to just one of the rear wheels - significantly improving the SLR's cornering ability.

I'm curious to see some 1/4 mile times and track time. It should be good on both!

Hmmm, i'm curious myself. I wonder if RENNTECH modified the launch program (if any). I can only imagine the neck-snapping effect when you launch off the line

Not no launch program on the SLR. Never been a fan of this batman like design either. Much rather have the SL65 AMG Black Series or the CLK DTM AMG.
