Chrysler Crossfire SRT-6
The Chrysler Crossfire SRT-6 is one of the most unusual products to emerge from the DaimlerChrysler merger of 1998. Essentially a restyled Mercedes-Benz SLK 320 underneath its distinctively American bodywork, the Crossfire SRT-6 combined Mercedes engineering with Chrysler styling and the performance expertise of the newly formed Street and Racing Technology division, resulting in a car that was simultaneously German and American in character.
The SRT-6 designation indicated the fitment of an AMG-developed supercharged version of the Mercedes 3.2-liter M112 V6 engine. The IHI supercharger boosted output to 330 horsepower and 310 lb-ft of torque, a substantial increase over the naturally aspirated Crossfire's 215 horsepower. The engine was paired exclusively with the Mercedes 722.6 five-speed automatic transmission, known internally as NAG1, which could be manually shifted through the console-mounted shifter.
The performance was genuinely impressive. The SRT-6 could reach 60 mph in 5.0 seconds flat and carry on to a limited top speed of 157 mph, figures that placed it firmly in the territory of cars costing significantly more. The Brembo front brakes, lowered and stiffened suspension, and limited-slip differential gave it the chassis control to match its straight-line speed, and the car could be driven aggressively with genuine confidence on twisting roads.
The Crossfire's body was designed in-house at Chrysler's Auburn Hills design studio, and its most controversial feature was the boattail rear deck that terminated in a sharp, pinched edge reminiscent of a 1930s Duesenberg. The design was polarizing, eliciting either enthusiastic admiration or puzzled disapproval depending on the viewer. The SRT-6 added unique front and rear fascias, side skirts, a rear lip spoiler, and larger exhaust tips that gave the car a more aggressive visual presence than the standard model.
Built by the legendary German coachbuilder Karmann at its Osnabruck plant, the Crossfire benefited from manufacturing quality associated with German precision rather than Chrysler's sometimes inconsistent domestic production. The Mercedes-derived chassis, suspension, and drivetrain components were also of a notably higher quality standard than typical Chrysler fare, giving the car a solidity and refinement that surprised many who expected an American badge to indicate American-level build quality.
The interior was a blend of Chrysler and Mercedes components, with the basic dashboard architecture, switchgear, and HVAC controls sourced from Mercedes, while the leather seats, steering wheel, and trim materials were Chrysler-specific. The cabin was intimate and well-appointed, though it lacked the spaciousness expected of a car at its price point.
Sales of the Crossfire were modest, and the SRT-6 accounted for only a small fraction of total production. The car suffered from its unclear identity: too expensive for Chrysler loyalists, too Chrysler-badged for Mercedes shoppers, and too automatic-only for dedicated sports car enthusiasts. The dissolution of DaimlerChrysler in 2007 effectively sealed the Crossfire's fate, and it was discontinued without a successor.
Today, the Crossfire SRT-6 represents remarkable value on the used market, offering genuine Mercedes-AMG supercharged performance at a fraction of the price of an equivalent SLK 32 AMG. The German build quality and engineering ensure durability, while the Chrysler badge keeps prices accessible for enthusiasts who prioritize driving experience over badge prestige.
The Mercedes M112 supercharged V6 is robust but check supercharger bearings for whine and intercooler pump function. The 722.6 transmission is reliable but conductor plate and speed sensor failures are common. Inspect for rust on underbody components and exhaust heat shields. The rear subframe mounts can develop cracks. Mercedes OEM parts fit but are sometimes listed differently under Chrysler part numbers. Avoid cars with deferred maintenance on the supercharger drive belt.
Built by Karmann in Germany on the Mercedes R170 SLK platform. The supercharged AMG engine was shared with the SLK 32 AMG and C32 AMG. The NAG1 five-speed automatic was the only transmission option. Production ended when the DaimlerChrysler merger dissolved.
