It has smashed 13 track records, but how?
Have you ever wondered what makes the mighty Dodge Viper ACR so great? It’s definitely not an easy job to create a successful mix of a naturally-aspirated V10 engine, a six-speed manual gearbox, a Brembo brake system hiding under 19-inch wheels, and super effective aerodynamic package - all coming for the price of $117,895.
That’s where science comes to help. Shortly after our cutaway drawing of the 2003 Viper SRT-10, the guys over at Engineering Explained have published a new video on their YouTube channel, giving a comprehensive look at the performance figures of the Viper ACR and comparing them with a Ferrari 488 GTB.
The video reveals that the car’s aerodynamics produce more than 1,200 pounds (544 kilograms) of downforce at speeds of 150 miles per hour (241 kilometers per hour) and more than 1,700 lbs (771 kg) at 177 mph (285 kph). The special Kumho Ecsta V720 tires designed specifically for the vehicle give it a skidpad rating of 1.15 g's. “It's incredibly fast, so let's do some math to explain how it can beat the competition,” the video description says.
Since its debut, the Viper ACR has managed to beat the records of 13 different tracks. These include Laguna Seca, Road Atlanta, Waterford Hills, Motorsport Ranch, and others. However, the end of the road for the V10-powered beast is coming, as Dodge has decided to end the production of the Viper in all its variants.
The last year was not very successful for the model in terms of sales, but the brand is planning one last production run and will open order books by the end of the year. We don’t know how many examples will be assembled, but we highly doubt the number will be bigger than 200.
“The demand for ACR is off the charts — way more than we ever expected,” Tim Kuniskis, head of Fiat Chrysler-North America passenger-car brands, commented to The Detroit Press. “We are close to opening it back up now that we know how many more we can build. They will sell out quickly.”
