2006 Cadillac XLR-V Review

Cadillac’s V-series is to that nameplate what AMG is to Mercedes or M is to BMW. It’s the high-performance wing of the company, where the original product (and its price) gets kicked up some serious notches. It is also a pretty brave enterprise at Cadillac. Running up your colors in the company of cars that define the art of corporate hot rodding is an unmistakable signal of intent.

With its XLR- V, Cadillac puts a player in among the SL55 AMGs and Jaguar XKRs of the world — cars with performance and pedigree to spare. So how does the XLR- V match up, this low-slung, high-end pretender to the thrones of Europe?

In some areas, very well indeed. The new 4.4-liter supercharged version of GM’s Northstar V-8 is an exceedingly sophisticated engine. Pressurized by a GM-designed and -patented Roots-type blower made by Eaton, the engine supplies prodigious torque throughout most of its operating range. Continuously variable valve timing at all four cams undoubtedly helps spread the available torque around so the car almost always responds to a jab at the pedal with a surge of acceleration.

The Northstar is also endowed with desirable versatility, able to purr around at lower engine speeds as befits a luxury marque, then snarl to the redline with almost shocking ferocity. Part of this Jekyll-and-Hyde act is due to a muffler that suppresses low-rev noise levels and then switches to a more free-flowing mode at higher speeds when a vacuum-operated valve opens, allowing the exhaust gases a more direct path to the atmosphere.

Also part of this suave schizophrenia is a host of detail work done on the Northstar to retain necessary levels of refinement along with elevated power output. The reduction in displacement (from 4.6 to 4.4 liters) was achieved by reducing the size of the cylinder bore — thus increasing the amount of metal between those cylinders — and was considered necessary in the interests of durability. That blower is housed in a casting that is integrated with the Laminova tube-type intercooler and the intake tract in one rigid unit, and it works extremely well at reducing unwanted supercharger whine.
