Chrysler Built An 850-HP Quad-Turbo V12 Supercar In Under A Year, Then Killed It
In the early 2000s, Chrysler set out to challenge Europe’s finest supercars. Its engineers developed a mid-engine machine with 850 horsepower, four turbochargers, and performance figures that threatened the world’s fastest cars. They went from an ambitious concept to a working prototype in less than a year, proving Chrysler could compete with established exotic brands. But the ambitious project never reached production, despite its impressive specifications and promising track tests.
Chrysler Once Wanted To Compete With The World’s Best Supercars
The early 2000s delivered some extraordinary supercars. Ferrari introduced the 651-hp Enzo, Porsche launched the V10-powered Carrera GT, and Mercedes-Benz partnered with McLaren to develop the supercharged SLR. These manufacturers had decades of performance engineering experience and wealthy customers ready to pay for it. Chrysler had a different reputation, built largely on sedans, minivans, and affordable vehicles.
The DaimlerChrysler era offered a chance to change that. Following the 1998 merger, Chrysler gained access to Mercedes-Benz engineering expertise and advanced powertrains, including AMG engines. Executives saw an opportunity to transform the brand’s image with a world-class supercar.
Chrysler’s leadership wanted a supercar that could showcase the DaimlerChrysler partnership’s engineering potential. The initial concept reached its public debut in less than a year. Executives Dieter Zetsche and Wolfgang Bernhard supported exploring production if the business case made sense. After the unveiling, Chrysler’s Street and Racing Technology division had to turn the show car into a working prototype. Under SRT chief Dan Knott, a small team completed a drivable development car in roughly four months.
The project demanded a new mid-engine platform, lightweight construction, advanced suspension, and aerodynamics suited to extreme speeds. Engineers also had to manage immense engine heat and torque while maintaining predictable handling. They drew on SRT’s experience with vehicles such as the Dodge Viper, although the new car required a different approach. While most manufacturers spend years developing supercars, Chrysler’s team had months.
The Chrysler ME Four-Twelve Packed 850 HP Into A 2,880-Pound Supercar
Chrysler unveiled the ME Four-Twelve at the 2004 North American International Auto Show in Detroit. Its name explained the mechanical layout: ME stood for mid-engine, Four represented its four turbochargers, and Twelve referred to the V12. Designer Brian Nielander helped shape its low, wide body, complete with large air intakes and sharp aerodynamic surfaces. Chrysler later built a matte-black development prototype that demonstrated its abilities at Laguna Seca, although production approval never came.
An AMG-derived 6.0-liter V12 powered the ME Four-Twelve, with four turbochargers boosting output to approximately 850 horsepower and 850 lb-ft of torque. Mounted behind the cabin, the engine drove the rear wheels through a Ricardo-developed dual-clutch transmission. Chrysler planned a seven-speed gearbox for production, while the running prototype used a six-speed version. Dual-clutch transmissions were still uncommon in road cars in 2004, making the setup particularly advanced.
Weight was another priority. The ME Four-Twelve combined carbon-fiber body panels with a carbon-fiber and aluminum-honeycomb chassis, targeting a curb weight of 2,880 pounds. Chrysler claimed the car could accelerate from 0–60 mph in 2.9 seconds, cover the quarter-mile in 10.6 seconds, and reach a theoretical 248 mph. Racing-inspired pushrod suspension, carbon-ceramic brakes, and advanced aerodynamics completed the package.
Those projected figures were remarkable. The Ferrari Enzo topped out around 217 mph, while the Porsche Carrera GT managed approximately 205 mph. Even the Mercedes-Benz SLR McLaren had a claimed top speed of roughly 208 mph. If Chrysler’s estimates proved accurate, the ME Four-Twelve would have ranked among the fastest production cars ever built.
The prototype still needed refinement, however. During a 2004 MotorTrend drive at Laguna Seca, engineers limited torque to around 553 lb-ft to protect the transmission. The test car also weighed closer to 3,200 pounds than Chrysler’s proposed production target. Journalists praised its acceleration and braking but noted that the suspension and gearbox calibration needed work. Given the rushed development schedule, those issues were hardly surprising.
Why Chrysler Abandoned Its Ferrari-Killing Supercar
A working prototype was one thing, but producing a road-legal supercar required a far greater investment. The ME Four-Twelve used a bespoke chassis, expensive materials, and a complicated drivetrain that Chrysler couldn’t manufacture on existing assembly lines. Engineers still needed to address reliability, cooling, crash safety, emissions compliance, and everyday drivability. Limited production volumes would make recovering those costs difficult.
Pricing created another obstacle. Early speculation suggested the ME Four-Twelve might cost around $150,000, but later estimates climbed to between $250,000 and… $750,000. That would put Chrysler directly against Ferrari, Porsche, Lamborghini, and other established exotic manufacturers. At those prices, buyers expect more than speed: brand prestige, racing heritage, and exclusivity all influence purchasing decisions. Chrysler had the horsepower, but convincing customers to spend Ferrari money on a Chrysler would be difficult.
Reported tensions within DaimlerChrysler added another layer. Some accounts suggest Mercedes-Benz insiders worried the ME Four-Twelve could overshadow the SLR McLaren. Mercedes had invested heavily in its flagship, yet Chrysler’s creation promised more power and a higher theoretical top speed using an AMG-derived engine. However, no conclusive public evidence shows Mercedes executives directly ordered the project’s cancellation.
By 2005, the ME Four-Twelve’s production prospects had effectively disappeared.
Chrysler looks very different in 2026. Its lineup centers on minivans, with the Pacifica and Voyager representing the brand’s offerings. For 2027, Chrysler is integrating the Voyager into the Pacifica range as the Pacifica LX, reinforcing its focus on family transportation. That’s quite a contrast with a company that once considered building an 850-hp supercar to challenge Ferrari and Porsche. Chrysler helped popularize the modern minivan, so its current direction makes commercial sense. Still, few enthusiasts would have predicted such a dramatic change two decades ago.
