Dodge Viper RT/10 (1992–1995): Collector Spec Sheet

The first-generation Dodge Viper RT/10 is the rawest version of America’s most deliberate supercar: a tubular frame, a fiberglass body, an 8.0-liter V10 and, in the earliest cars, no roof worth the name, no door handles and no anti-lock brakes. It is also now one of the more accessible collector cars with real supercar credentials. Hagerty’s October 2026 guide puts a 1993 car in #3 (good) condition at $35,200. Below: the production numbers, the identifying details, the weak points and where values sit, so you can tell a good RT/10 from a tired one.

Specifications from Hagerty’s valuation page and Wikipedia’s SR I article. Where they differ, we show both.

Production totals

Hagerty gives year-by-year production for the RT/10 era. The total is our sum of its figures.

The 1992 cars are the scarcest by a wide margin, and the 1994 model year accounts for roughly half of all first-generation production. A 1992 car is the one collectors chase; a 1994 or 1995 is the one that is usable.

Engine and drivetrain

The V10 began as a Dodge truck engine concept before Chrysler asked Lamborghini to help design an aluminum block and heads, keeping the two-valve pushrod layout. It is rated at 400 horsepower with a 6,000-rpm redline, and it feeds the rear wheels through a BorgWarner T56 six-speed manual. Wikipedia notes a claimed 0.95 g in corners and EPA figures of 12 mpg city and 20 mpg highway, helped by tall gearing. A pre-production Viper paced the 1991 Indianapolis 500 with Carroll Shelby at the wheel, and production roadsters went on sale in January 1992.

Special options and equipment

• Air conditioning. A dealer-installed option in 1993 and a factory option in 1994 (Hagerty); Wikipedia says later 1994 cars.
• Adjustable suspension. Listed as an option by Wikipedia.
• Factory hardtop. A true single-piece removable hardtop arrived for 1995. Most cars from this generation came with only a canvas top with plastic side windows.
• Standard equipment. Manual leather sport seats, AM/FM cassette, power brakes and steering. The cars have no airbags, traction control or ABS, and none of the early cars has exterior door handles or key cylinders.

Identifying details

• Red paint with a gray interior identifies the 1992 model year, the only configuration Hagerty says was delivered that year.
• No exterior door handles or lock cylinders; entry is by reaching inside through the unzipped side window to the release.
• Side-exit exhaust pipes, whose heat is part of the car’s reputation.
• The one-piece factory hardtop signals a 1995 car or a later addition, so ask whether it is original to the car.
• The generation ends with the 1995 model year; the 1996 GTS coupe and later RT/10s belong to the SR II era.

Common weaknesses

Hagerty calls Viper ownership relatively low-cost and trouble-free next to other exotics, and lists the following points to check:

• Valvetrain wear. The engine can develop valvetrain issues with wear, or if it was not broken in properly.
• Hard or track use. Look for signs of it, and check the front valance and side pipes for curb damage or makeshift repairs.
• Interior exposure. Most cars lacked a tight-fitting top, which left the interior vulnerable to the elements, so Hagerty advises choosing a car stored in a dry, climate-controlled garage.
• Cabin heat. The side exhaust warms the cabin noticeably at low speeds and can scorch a leg when getting in.
• Driving manners. Near the limit, early cars bite back, with no ABS or stability control. That is a trait of the car, not a defect, but it matters to the buyer.

Current value range

Per Hagerty’s October 2026 price guide, a 1993 RT/10 in #3 (good) condition is worth about $35,200, with a high-low band of $31,200 to $38,333, a quarterly change of +2.9%, an annual change of −3.3% and a three-year change of −12.2%. Hagerty’s 12-month data for 1992–1995 Vipers shows 58 cars sold at an average of about $51,200, with sales volume up 14%. The three-year auction range for a 1993 car runs from $8,525 to $150,000, which tells you how much condition and provenance matter.

The market has been correcting. In April, Hagerty reported that every 1992–2010 Viper fell in the guide, with the earliest RT/10s down 10% in the quarter and 21% from their late-2021 peak to a #2 (excellent) value of $44,600, not far above where they stood in early 2020. The October figures show the first-generation car stabilizing, with a small quarterly gain.

What separates a good RT/10 from an average one

• Mileage and use. The 2,800-mile car above brought roughly 20% more than the 13,000-mile car, and well-documented low-mile cars lead the top end of the range.
• Engine health. Evidence of a proper break-in, correct maintenance and a clean leak-down or compression test.
• Unmolested bodywork. An undamaged front valance, side pipes and fiberglass, with no track-day scars or repainted panels.
• Dry storage. A car that lived under cover, with an interior free of mold, sun damage and water stains.
• Correct year-specific features. A 1992 in red over gray is the collector’s pick; later cars should have documented air conditioning or a factory hardtop if the seller claims them.
• Originality. Factory wheels, exhaust and top, with any modifications disclosed.

Are you chasing the red-over-gray 1992, or is a usable 1994 the smarter way into a Viper?
