The 2015 Dodge Viper SRT — Dodge is back in the Viper game these days, remember — will soon arrive with a new GT trim, a new Time Attack version, new colors and a 5-hp bump from last year’s 640-hp V10. The company laid out its plans for the 2015 Viper in a press release on Tuesday.

The GT model adds a driver-selectable suspension with Bilstein shocks, a five-mode electronic stability-control system and an upscale interior usually reserved for GTS trims. The GT will fall, pricewise, in between the base car and the GTS. Prices will be announced later; the current car will set you back about $100,000.

The Viper Time Attack returns in version 2.0. Dodge says the TA is built specifically for enthusiasts who want to take their car to the track. Changes have been made to the aerodynamics, which lead to 400 pounds of downforce at 150 mph. Other changes include race-tuned suspension calibration, racing sway bars, a lighter X-brace, two-piece Brembo brakes and Pirelli P Zero Corsa tires on “Sidewinder” wheels. The TA is offered in three colors: competition blue, yorange (we’re guessing a yellowish orange) and venom black.

The top GTS model comes with all the interior bells and whistles like Alcantara trim, napa leather and carbon fiber. The new Ceramic Blue Edition, limited to 40 examples, gets a satin black exhaust bezel, ceramic blue fuel filler door, orange brake calipers, carbon-fiber brake ducts and rear appliqué.

Output goes up 5 hp for a total of 645 hp; torque stays at 600 lb-ft in the 8.4-liter V10. A Tremec six-speed manual routes power to the rear wheels. Top speed is pegged at 206 mph, while mileage on the highway is 20 mpg.

Stryker purple, a new color, will now be available on the GT and GTS models. Exterior stripes can be had in black, silver, white, red and pearl.

ROAD TEST EDITOR JONATHAN WONG: I’m all for raw, no-frills cars. Things like the Subaru BRZ/Scion FR-S, Mazda MX-5, and Lotus Exige and Evora are cars that don’t pack much in terms of whiz-bang …
