Although Chrysler considered ending production because of serious financial problems,[1][2] on September 14, 2010, then–chief executive Sergio Marchionne announced and previewed a new model of the Viper for 2012.

But then Chrysler chairman Lee Iacocca delayed approving the $70 million needed to put the sports car into production, saying it was a lot to spend without assurance of financial return.

[14] Originally engineered to be a performance car, the Viper had no exterior-mounted door handles or key cylinders and no air conditioning (however, this was added as an option for the 1994-95 models, and climate controls featured a "snowflake" icon, which indicated a potential setting for the A/C).

However, the Viper was still equipped with some domestic features, including manually-adjustable leather-trimmed sport bucket seats with lumbar support, an AM/FM stereo cassette player with clock and high fidelity sound system, and interior carpeting.

The exposed side exhaust pipes on the RT/10 roadster were relocated to a single muffler at the rear exiting via two large central tailpipes during the middle of the model year, which reduced back pressure, and therefore increased the power to 415 hp (309 kW; 421 PS).

TSB (Technical Service Bulletin) recalls (998 and 999) were done at local dealerships to repair the 1996 to 1999 Viper frames by adding gussets with rivets near the steering box.

An even lighter and stronger aluminum space frame chassis was in development for the next generation model, but the project was shelved because of parent company Chrysler's financial crisis.

In 2004, Dodge introduced a limited-edition Mamba package; Mamba-edition cars featured black interiors, with red stitching and trim, price increased by about $3,000.

The Dana M44-4 rear axle from the 2003–2006 model now had a GKN ViscoLok speed-sensing limited-slip differential that greatly helps the tires in getting grip under acceleration.

Changes included a 180-amp alternator, twin electric cooling fans, electronic throttles, and completely new VENOM engine management system.

Kuno Wittmer piloted a street legal 2010 Dodge Viper ACR to a record lap of 1:59.995 at Miller Motorsports Park in Tooele, Utah, on Monday, April 11, breaking the 2-minute mark for the first time in a production car on the 3.048-mile Outer Course configuration.

[31] At a dealer conference on September 14, 2010 in Orlando, Florida, the then Chrysler Group and Fiat CEO Sergio Marchionne was reported[32][33] to have concluded his remarks by unveiling a rolling 2012 Dodge Viper prototype.

Its upgrades were more drastic than the original, including street-legal racing tires (Michelin Pilot Sport Cups which Michelin describes as "Ultra-High Performance Sport tires"),[46] two-piece brake rotors, adjustable suspension, and significant aerodynamic enhancements that included a front splitter, canards and a carbon fiber adjustable rear wing.

Weight was also decreased by 40 lb (18 kg) by using the "Hardcore Package", that deletes the A/C, radio, speakers, amplifier, trunk carpet, hood pad and tire-inflator.

The aerodynamic components were produced by Plasan Carbon Composites and assembled to the vehicle by Prefix Corporation located in Rochester Hills, Michigan.

[47] On September 14, 2011, on the Nürburgring, a 2010 Dodge Viper SRT10 ACR completed the sixth fastest production, street-legal car lap ever recorded with a 7:12.13 elapsed time.

[60] Despite the failure of surpassing the Huracán Performante, the team was still able to make the Viper ACR the fastest American, rear-wheel driven (with no additional assistance), and manual transmission equipped car to go around the track.

[65] The car now had the addition of the Advanced Aerodynamic Package (two-piece front corner splitters and a rear decklid spoiler made from carbon fiber), lightweight Sidewinder II wheels finished in matte-black, Pirelli P Zero Corsa tires, two-mode (Street and Race) Bilstein DampTronic suspension adapted from the GTS, but with firmer levels of damping and a smaller spread between modes, shock dampers, increased spring rates and thicker anti-roll bars, carbon fiber underhood X-brace (instead of the aluminium brace in all other models), carbon fiber rear tail light applique from the Exterior Carbon Fiber Accent Package, two-piece Brembo brake rotors with wider brake annulus, black-anodized Brembo brake calipers painted with the Viper logo in TA Orange, TA logos behind both front wheels and a Stryker decal instead of the standard badge on the hood (TA Orange on the Venom Black cars, black on the TA Orange and Venom White cars), black interior with TA Orange accent stitching on the ballistic cloth seats, instrument panel & cowl, center stack, console, hand brake, shifter boot, and door panels.

A prototype 2008 Mopar Viper coupé, with 675 hp (503 kW), appeared at the 2007 North American International Auto Show, but was not planned for production.

Along with the carbon fiber hardtop, a front splitter and rear wing were added; however those parts were not nearly as significant as those on the later SRT-10 ACR, and no downforce/drag information was provided to show that they were even functional.

[76] The Chrysler Firepower was a grand touring concept based on the Viper chassis that would have been equipped with the Hemi V8 engine coupled with an automatic transmission.

Changes include yellow body colour, carbon fiber parts at underhood, exposed carbon fiber performance cross X-Brace trimmed in a satin finish, a decal-cut Viper "Stryker" logo in the center of X-Brace, engine cover in carbon fiber and aluminum with the SRT logo, prototype aluminum oil filler cap with the SRT logo, a carbon fiber aero package, Mopar coil springs, full black interior with yellow accents, Sabelt hard-shell seats with a six-point safety harness, seat edging in black Katzkin leather with yellow accents in the perforations, Mopar billet aluminum shift knob, billet aluminum HVAC bezels and controls, carbon fiber bulkhead satchel with a universal integrated quick-release camera mount, polished chrome door-sill guards with the Viper logo, race-inspired sand-blasted aluminum Mopar bright pedal kit with the Viper logo etched in the pedals, footrest pedal with "Stryker" logo, optional "Track Pack" wheels finished in hyperblack, a front tow hook and an LED fog lamp kit.

Oreca finished the year with three races in the BPR Global GT Series getting an eighth place at Brands Hatch, ninth at Spa, and sixth at Nogaro.

In 2006, a modified Dodge Viper GTS-ACR driven by Greg Crick under the team Crickcars.com entered the Australian GT Championship and won it, with 713 points in total.

Modifications to the mechanicals of the Viper included a 27-gallon fuel cell, differential cooler, ducted brakes, improved driver and engine cooling, trap door oil pan, low-inertia flywheel, an improved double-wishbone suspension system, new spherical bearing control arm attachments, two-way adjustable coil over dampers, and a driver-adjustable blade-type rear anti-roll bar.

The racing team entering 2012 ALMS included Dominik Farnbacher, Marc Goossens, Ryan Hunter-Reay, Tommy Kendall, Jonathan Bomarito, and Kuno Wittmer.

[96] Balance-of-performance regulations encouraged the car to run an unusually low rev limit of 4,700 rpm at Le Mans, taking advantage of the large V10 engine's low-end torque.

[97][98] In 2014, with the ALMS folding and merging with the Rolex Sports Car Series, SRT soon entered the TUDOR United SportsCar Championship GTLM class.

93 Viper won class at Indianapolis Motor Speedway Brickyard Grand Prix in July 2014, after both cars took podium positions in the previous races at The Glen and Mosport.

The lap times were set by racing drivers Randy Pobst, Tommy Kendall, Lance David Arnold, and SRT vehicle dynamics and development engineer Chris Winkler.
