SL55/63/65/R230 AMG: Cadillac XLR-V "Challenge to the SL55's throne"
Heres the Specs....
2006 XLR-V: Ultra-Luxury, Under-5 Performance
The 2006 Cadillac XLR-V – the newest addition to the luxury nameplate’s growing family of high-performance V-Series vehicles – establishes a new benchmark for the ultra-luxury class of high-performance roadsters in power, performance and personal amenities.
Like its mainstream XLR sibling, the XLR-V combines distinctively bold styling with contemporary luxury, ingenious technologies, rear-wheel-drive performance, and near 50/50 weight distribution for enhanced balance and vehicle dynamics – yet it does so on an entirely different level:
Equipped with a supercharged Northstar engine and rear-mounted six-speed automatic transmission, the high-performance luxury roadster effectively delivers 0-to-60 performance in under 5 seconds
Exterior and interior appointments clearly identify the two-seater as a V-Series family member, including application of a signature wire-mesh grille, larger 19-inch wheels at all four corners, and ebony wood and aluminum accents throughout the interior
Chassis refinements enable surefootedness on the street or the track and include larger brakes, stabilizer bars, wheels and tires, a performance-calibrated Magnetic Ride Control (MR) system
An Adaptive Forward Lighting system, a first-time application on a Cadillac, which automatically adjusts headlamp direction up to 15-degrees for improved night driving vision
Like XLR, the XLR-V will be built at GM’s state-of-the-art, award-winning Bowling Green assembly center.
XLR-V's Supercharged Northstar Engine
At the heart of the XLR-V is the new, 4.4-liter version of the Northstar engine outfitted with a positive displacement intercooled supercharger. The dual overhead cam (DOHC) V-8 engine delivers the highest horsepower rating of any Cadillac engine to date.
Called the Northstar V-8 SC (supercharged), the engine produces 440 horsepower (328 kW) at 6400 rpm and 425 lb-ft (576 Nm) torque at 3600 rpm (power and torque figures estimated) – and the engine’s power is underscored by its ability to deliver 90 percent of its peak torque between 2200 and 6000 rpm.
The aggressive torque curve enabled by the choice of a supercharged engine gives the XLR-V acceleration capable of placing it firmly in the under-5-second-club for 0-to-60 time – a signature capability of V-Series vehicles.
Six-Speed Automatic Transmission
The Northstar V-8 SC is mated to the all-new Hydra-Matic 6L80 six-speed automatic transmission – the first use of General Motors’ new six-speed automatic in a rear-mounted configuration.
The 6L80 – the only transmission offered on the XLR-V – is one of the most technologically advanced automatic transmissions in the industry, using clutch-to-clutch operation and an advanced integrated 32-bit transmission controller to deliver smooth and precise shifts. In addition, a wide 6.04:1 overall ratio spread enhances performance and fuel economy.
Performance-Tuned Chassis Systems
Chassis modifications found on the XLR-V when compared to its mainstream sibling include larger brakes; recalibrated Magnetic Ride Control (MR); larger front stabilizer bar and the addition of a rear stabilizer bar; stiffer rear lower control arm bushings; larger wheels and tires; a power steering fluid cooler; and a higher-capacity fuel pump.
The most noticeable change is in the braking system to assure strong stopping power and smooth, confident brake operation, coinciding with the increased power and handling capabilities of the XLR-V.
To achieve this, chassis engineers turned to J55 brakes, essentially the same application used in the Z51 Corvette with larger cross-drilled rotors and high-performance brake lining. Front rotors are 13.4-inches (340.4 mm) in diameter; rear rotors are 13.0-inches (330.2 mm). The thickness of the rotor cheeks on both the front and rear has been increased for added thermal capacity. The brake system incorporates dual-piston front calipers, and single-piston rear calipers.
Magnetic Ride Control on the XLR-V has been recalibrated to account for the enhanced handling characteristics the roadster’s surpercharged performance demands. The system seeks to keep the body on an even plane at all times, giving drivers a comfortable ride by dramatically reducing disturbances to the vehicle body.
Wheels and tires have been increased in size for enhanced sure-footedness, to 235/45 R19 on the front and 255/40 R19 rear. The tires are Pirelli run flats.

Personally I don’t think that the 55's throne will be challenged, but Automobile mag seems to think it will be a worthy contender.
i think it looks neat. ive only seen older ppl drive em in newport tho....

The Best of Mercedes & AMG
My guess is the XLR-V will outperform an SL55 on a road course due to it's weight advantage. At a drag stip, I'd pick the SL55...
They'll never equal the SL55's sales volume but it'll sell for a few reasons:
1. It's cheaper than an SL55.
2. For a person that want's an upscale, good looking, high performance convertible for less than 6 figures... the XLR-V is a good choice.
3. Some people (including myself) find the XLR to be a hot looking car.
Having said that, I wouldn't pay around $90 grand for it, simply because it isn't my kind of car. I'll lease a Porsche GT3 before any car in the 95-105K price range.
