Chrysler Crossfire SRT-6

Chrysler Crossfire SRT-6 - The car's name is also an unintentional pun about DaimlerChrysler; in the days since the 1998 merger, executives have been regularly mowed down by crossfire between Stuttgart and Detroit. The latest forced exit was Chrysler Group COO Wolfgang Bernhard, crossfired in May for being too vocal about problems at Mercedes and resisting a plan to spend $7 billion bailing out Mitsubishi.

Meanwhile, the dandy-dressed Crossfire, which shares both skeleton and muscle with the first-generation Mercedes-Benz SLK roadster, is the first Chrysler product to attain the performance-enhancing SRT label, heretofore bestowed only on Dodges.

The "street and racing technology" shtick—adding more horsepower, bigger tires, and big attitude—has already been done to a few Dodges, notably, the Ram SRT-10 and Neon-based SRT-4 (all Vipers carry an SRT-10 badge). Buyers who prefer a quick quarter-mile served with essence of tire smoke have approved of the 500-hp pickup and 230-hp subcompact (in fact, various Mopar bolt-on kits will bump the SRT-4's horsepower all the way to 300).

We have written that the base Crossfire has eye-snaring looks and pleasing handling but an engine at least 50 horsepower short of the boiling point. The SRT mods are substantial, as is the price increase. From base Crossfire coupe to SRT-6 coupe, the extra $11,200 buys first and foremost an intercooled supercharger that wrenches another 115 horses from the 3.2-liter, 18-valve V-6. Blown, the V-6 makes 330 horsepower and 310 pound-feet of torque, a twistability increase of 81 pound-feet.

There's been considerable pumping up of the Crossfire's suspension as well. The spring rates have been stiffened almost 50 percent in the front and 42 percent in the rear, and jounce and rebound rates in the shocks have been firmed up to match. The front brake rotors grow 1.2 inches to 13.0, and the rear discs go vented and get another 0.9 inch of diameter. There's more zoot in the Crossfire's '40s-streamline styling with special-to-SRT wheels, 18 inches in front, 19 in the rear.

The cockpit gets by with minimal changes, including a 200-mph speedo and Alcantara pseudo-suede trim on the buckets that is embroidered with an SRT-6 logo. Hence, a few complaints about the Crossfire cabin remain, including over-the-shoulder blind spots, a tight cabin for six-footers, no steering-wheel rake adjustment, and a dinky eight-cubic-foot trunk with nothing to tie down the goods.

Even so, polite manners govern the powertrain. The throttle response and the automatic gear selections are smoothly keyed to your pedal inputs. If you like, pilot the SRT-6 all day without ever getting into the fat end of the power—let the Starbucks get cold in the one cup holder, and it won't slosh if you're careful.

Fancy multilink arrangements in the wheel wells strike a contrast to a medieval recirculating-ball steering box that deadens wheel feedback from the driver. The base Crossfire is no lubberly pig, but the SRT deckhands have pulled in any slack and reprogrammed the stability-control software to tolerate more friskiness. Some fast lapping at Southern California's Willow Springs track proved that the SRT-6 is screwed down tight.
