Was the Dodge Stealth twin turbo?
Yes. The Dodge Stealth did offer a twin-turbo variant—the RT/TT—based on Mitsubishi's 3000GT VR-4 platform, and it served as the high-performance flagship of the Stealth lineup from 1991 through 1996 in the United States.
Origins and collaboration
The Dodge Stealth was the American badge for Mitsubishi’s high-performance two-door sports car. Beginning in the early 1990s, Chrysler and Mitsubishi collaborated to bring the 3000GT to North American buyers under the Dodge name. The partnership allowed Dodge to offer a homegrown alternative to rival performance coupes while sharing the sophisticated drivetrain and technology developed by Mitsubishi.
Under this arrangement, the Stealth lineup included both naturally aspirated and turbocharged variants. The twin-turbo version—priced and marketed as the RT/TT or RT Twin Turbo—was the apex of the range, delivering substantial performance for its era by leveraging Mitsubishi’s VR-4 platform.
Twin-turbo variant: What it offered
Before outlining the key specifications, it helps to know what differentiated the twin-turbo Stealth from its less powerful siblings. The RT/TT was designed to compete with other late-1980s and early-1990s turbocharged coupes by combining a potent engine with all-wheel drive and performance-oriented tuning.
- Engine and propulsion: 3.0-liter DOHC V6 with twin turbochargers (VR-4)
- Drivetrain: All-wheel drive with performance-oriented suspension and braking
- Power and torque: Approximately 320 horsepower with torque around the mid-300 lb-ft range, depending on model year
- Transmission options: Five-speed manual standard, with a four-speed automatic available
- Branding and positioning: The top-tier Stealth model wore RT/TT badges signaling turbocharged performance
In practice, the RT/TT delivered stronger acceleration and faster sustained speed than the non-turbo models, which helped it stand out in its era as a legitimately sporty, all-weather ready coupe.
Production timeline and market presence
Exactly when Dodge offered the twin-turbo variant helps clarify its place in automotive history. The Stealth lineup, including the twin-turbo version, was available in the U.S. from the 1991 model year through 1996. The twin-turbo was the rare, high-performance option that contrasted with the base and mid-range variants, making it a sought-after model among enthusiasts who remember the era.
- 1991: Dodge introduces the Stealth platform in the U.S., with turbocharged options available in the lineup.
- 1992–1993: The twin-turbo RT/TT variant becomes the performance flagship, sharing Mitsubishi’s VR-4 drivetrain.
- 1994–1996: Continued availability of the RT/TT alongside other Stealth trims, with incremental refinements and ongoing reception among buyers.
The collaboration between Chrysler and Mitsubishi ended the Stealth’s run in the mid-1990s, but the model remains a notable example of cross-brand engineering from that era, and the twin-turbo variant is often cited by collectors and enthusiasts today.
Performance, pricing, and legacy
Today’s readers will recognize the Dodge Stealth RT/TT as a bridge between late-80s turbo performance cars and the more modern all-wheel-drive sports coupes that followed. While horsepower and torque figures varied by year and market, the twin-turbo Stealth offered strong acceleration, confident straight-line performance, and the all-weather capabilities associated with turbocharged AWD cars of its time.
In the broader automotive legacy, the Stealth RT/TT is remembered for encapsulating a rare period when American brands partnered with Japanese manufacturers to deliver high-performance machines with distinctive styling and a mix of European-influenced handling characteristics. For collectors today, well-preserved RT/TT models are prized for their historical significance and the distinctive experience of a twin-turbo, all-wheel-drive sport coupe from the early 1990s.
Summary
The Dodge Stealth did indeed offer a twin-turbo variant, known as the RT/TT, which used Mitsubishi’s 3.0-liter twin-turbo V6 in an all-wheel-drive package. Produced for the U.S. market from 1991 to 1996, the RT/TT stood as the performance flagship of the Stealth lineup, delivering strong straight-line speed and a distinctive joint venture heritage that still resonates with enthusiasts today.
