Click for hi-res gallery of the RENNtech SLR 722 PKG2

The Mercedes-Benz SLR McLaren may be on its way out, but that doesn't mean there can't be more horsepower extracted from the supercar. The original had 617hp. Then came the SLR 722, which despite its name had 650 horses underhood. The 722's American importer, RENNtech, addressed the perception gap with its first package, boosting output to an eponymous 722hp. Never satisfied to leave well enough alone, RENNtech has now released its second package for the SLR 722 that further boosts power to 740 thanks to a revised ECU and a freer-flowing exhaust system.

While RENNtech's PKG1 went for a solid $12,900 (come on, what's a lousy $13k on the price of such a supercar?), the new PKG2 costs a heftier $26,990, plus an extra $7,800 for the optional Signature 10-spoke 20-inch rims, which can be had in chrome, satin-ceramic or "sniper gray" finishes. The SLR won't be leaving without a final swan song.

With the mostly unloved Mercedes-Benz SLR McLaren set to get the official axe in 2009, the path is clear for the next McLaren-branded supercar to be unveiled. Expected to be built at its facility in Woking, England, McLaren has plans for the as-yet-unnamed vehicle to compete with Ferrari's incredible F430. Rumored to be powered by a 550-horsepower V8 engine featuring a basic design snagged from Mercedes and built by Mahle (that of the former Cosworth tuning fame), the power-to-weight ratio should handily outdo that of the Prancing Horse. Shortly after the new coupe codenamed P11 is unveiled, a convertible version is also expected.

True hardcore McLaren enthusiasts should mark 2012 as the year that McLaren returns to form with a proper replacement for its awe-inspiring F1 of a few years back. Powered by a lightweight version of the P11 architecture, this car codenamed the P12 is expected to be powered by a V10 engine with over 600 horsepower. The waiting list will likely start right... about... now.

It's been a long, drawn-out goodbye for the lackluster Mercedes-Benz SLR McLaren. The last of the original coupes rolled smoothly off the production line at the end of last year, and the subsequent SLR Roadster is set to follow in 2009.

The SLR drew criticism from the start as a wishy-washy compromise of a supercar with an automatic transmission, better suited towards boulevard cruising – of which it was capable in the grandest style – than white-knuckle driving. The future is looking brighter, however, as a whole array of mouth-watering supercars is popping up in the SLR's place. We brought you news yesterday that the SLR's supercharged V8 engine could find its way into the next Pagani. Before that we brought you spy shots of the upcoming SL65 AMG Black Series, whose performance promises to eclipse the SLR's at a fraction of the price. Mercedes is also preparing an even more extreme SLC with potentially even more blistering performance. McLaren, meanwhile, unhappy with the compromises forced upon it by Mercedes over the SLR project, is going its own way with the P11 project. With this cache of supercars coming down the road, we think it'll be rather hard to miss the SLR at all. Don't you?

OK, we've seen some of their previous work so we probably shouldn't have expected much more this time around, but when we heard that Mansory had gotten its hands on an SLR and a Ferrari 599 GTB, we certainly hoped that it would figure out a way to enhance their gotta-have-it quotients. Alas, our prayers went unanswered. Done up in a matte gold and black combo, the SLR looks a bit toy-like, but it should manage to sell in the single digits at least. Which digit you choose to count the sales is up to you. The Ferrari 599 GTB Fiorano had actually been criticized in some camps for being a bit too evocative of the Chevrolet Corvette when it was first shown. The Mansory edition done up in white and carbon fiber looks even more Vette-like to our eyes. Thoughts of a ZR1 or the recent 427 special edition Z06 leapt to mind. There was also a Phantom in the booth, but quite honestly, doing something outrageous to a Roller just doesn't offend us as badly. Take a look at the gallery and let us know if you agree. We've already heard from at least one other journo who happened to be winding his way down the road towards us that the 599 looks seriously racy and that we are dead wrong about it. We'll let you decide for yourselves. Click away.
