Tuner Tuesday: McLaren SLR Renntech Roadster

509

While I’ve always found the McLaren SLR an intriguing car, it’s never been a car that I fully understood. Following in the footsteps of the “Holy Grail” of supercars, the F1, the SLR just didn’t seem really that impressive in any way. Yes, it was fast. Yes, it sounded like a radial-engined airplane in full attack mode. Yes, the brakes caught on fire when it went too fast. But compared to the howling, scalded cat Carrera GT, the SLR just seemed a bit too main-stream. That was further hampered Mercedes-Benz itself when it offered supercharged versions of the SLs – which looked mostly like the SLR, had a nifty folding roof, offered most of the performance and cost a whole lot less. McLaren solved two of those questions in fairly short order; bumping horsepower up to nutty levels with the Edition 722 and also offering the McLaren SLR in convertible form. Today’s example isn’t a full blown 722 model, but has the big horsepower bump thanks to the wizards at Renntech:

I was at Goodwood for the launch of the SLR, and distinctly remember Gary Paffett doing a burnout at the top of the hill – I was only about 40 feet away. The car was just nutty and sounded like the whole world was coming unglued. Perhaps that was what was special about the SLR versus the F1; the F1 was all business and it showed; the SLR was insane when you wanted it to be, but when you got off the loud pedal it was effectively “just” a Mercedes. With the top down you can really experience that nuttiness on another level. Is it worth $280,000? Well, if you have the funds and want a basically new SLR Roadster, then yes, it surely is. For the rest of us probably not, but like many of the overpriced cars we featured I sure am glad they exist and I’ve gotten to see them along the way.

    I know these cars are fast from the factory so I can only imagine how insane a tuned version is. I just can’t get past the fact that these are the ugliest looking Mercedes ever produced, and that includes the W140 S class coupe and the C230 Kompressor coupe.
