2017 Dodge Viper

A 2017 Dodge Viper makes its way down the Conner Avenue assembly line.

Detroit Police Chief — and chief motorhead James Craig — crouches next to the black and white Dodge Viper that he drove at the head of Saturday's parade.

In the Viper pit, Detroit News auto critic Henry Payne gets ready to rumble in the parade up Woodward.

The 2017 Dodge Viper is the best — and last — of its breed. This Viper GTC (for "custom") sports the model's standard, 645-horsepower V-10 engine, plus ACR aero package, plus all-leather interior. It stickers for just $154,885.

The Dodge Viper's rocker panel-mounted exhaust pipes get so hot that Dodge puts a warning label on the door lest passengers burn their legs on exit.

The 2017 Dodge Viper's V-10 engine has grown since its 1992, 8.0-cylinder, 400-horsepower debut. Today, the engine is 8.4 liters with an output of 645 horsepower and 600 pound feet of torque.

The Dodge Viper ACR aero package features a front splitter and nose dive planes.

The 2017 Dodge Viper owns 15 track lap records in the U.S. — including M1 Concourse in Pontiac.

The 2017 Dodge Viper GTC/ACR features a distinctive rear wing, side exhausts and forward-opening front hood.

The 2017 Dodge Viper interior is not as spartan as the original 1992 model, and includes amenities like AC and a UConnect infotainment system. The cabin remains very loud, however — the better to hear the V-10 engine.

A line of 200 Dodge Vipers parade up Woodward Saturday, Aug. 12 to celebrate 25 years of the iconic supercar.

For 25 years, the Dodge Viper has exited its exhaust just below the coupe's two doors. And barbecued plenty of calves in the process.

The Dodge Viper's 8.4-liter V-10 is fast — and thirsty. On a full tank its range is under 200 miles while sucking down 10.8 mpg.

A large air duct aft of the front tires helps exit air from the 8.4-liter front engine, while a rear diffuser under the rear wing helps suck air out from under the car for better grip.

The 2017 Dodge Viper's unmistakable profile includes a long front hood to house its V-10 engine, and massive brake discs to bring the beast to a stop.

The 2017 Dodge Viper ACR is stripped of its interior for light weight — but it can still fit a large bag in the trunk.
