The Viper's sharp front edges and gaping maw are Braille for "get out of my way." A deep front spoiler and sloping hood wedged between two fenders help keep it from going airborne at three-mile-a-minute speeds, as does the subtle rear wing, rear suspension belly pan and the sizable diffuser under the rear end; don't back this up anywhere near a curb.

Cooling air is funneled in through the trademark four-slot grille and exhausted through six extractor vents in the hood; when idling or moving very slowly the hot air wafting out those vents makes the forward view distorted much like the rear window glass. Even the bubble top roof serves a purpose, enabling the occupants to fit with helmets on.

The roadster's folding soft top is manually-operated and stows neatly behind the seats but you must get out of the car to complete the five-second operation. The glass rear window has a defroster so visibility equals the coupe, and headroom is similar.

Xenon headlamps are standard, finally endowing the Viper with suitable vision for night drives; the snake's head center brake light continues. And like the earliest Vipers, the exhaust pipes, even on GTS coupes, exit right under the door ahead of the rear-wheel; expect drive-through attendants to ask you to turn it off so they can hear you.

The fuel tank is a bit smaller at 16 gallons (compared with the previous 18.5), but the engine is more efficient so range isn't severely impacted. Besides, 2.5 gallons of gas is just an extra 15 pounds you don't need in a race car.

Eight color choices are offered, with five choices in stripe color to complement or counter the primary shade. There are also three choices in wheels, although none is said to be significantly lighter than the others, so choosing them is mostly a style consideration.
