The world may have said farewell to the Dodge Viper late last week, but we’ve chosen to celebrate 19 years of production, not mourn it.

Think you know your snake history? We’ve rounded up a crop of Vipers, Viper variants, or Viper-powered vehicles for this week’s guessing game. Think you know what’s featured in the photo above? Send us your best guess in the comments section below.

Did You Surmise Yesterday’s Snake?

The tube-frame bracing in the engine compartment may have helped tip you off to the fact that yesterday’s car was, in fact, the Viper Competition Coupe.

Launched in 2003, the Competiton Coupe was billed as a turn-key, non-street-legal race car customers could order directly from their friendly local Dodge dealer. Built from the ground up by Roush Industries (the same firm currently transforming ACRs into the ACR-X), the car was purpose-built for the track, and stripped nearly 380 pounds of non-essential content (i.e. A/C, interior trim, stereo, etc.) from the cabin.

Although the ACR-X is another mean, track-only Viper, we dig the CompCoupe for its looks, which are copied almost directly from the intense Viper GTS/R concept shown at the 2000 Detroit auto show. When the second-generation production coupe launched in 2005, its lines — particuarly the rear fascia — were much softer.

More than two decades ago, McLaren began its journey to build “the finest sports car the world has ever seen.” That journey would eventually lead to the famous McLaren F1, a supercar penned by Gordon Murray and deemed to be one of the best street-legal race cars ever produced.

Taking cues from its F1 endeavors, the McLaren F1 road car utilizes a carbon-fiber shell that weighs just 220 pounds yet offers impressive rigidity. A BMW-sourced 6.1-liter V-12 puts out 627 horsepower and 586 pound-feet of torque, lofty numbers even by 2010 standards, while a 2500-pound curb weight, ABS-less brakes, and a finely honed double-wishbone suspension kept drivers tuned onto the road. Famously, the F1 had a central seating position, which led to the addition of two passenger seats for a three-seat configuration.

As the F1 road car made headlines for its impeccable handling, detailed packaging, and 3.2-second 0 to 60 mph time, the McLaren crew would also lend their talents to the ongoing racing effort. Three different F1-based race cars were produced from 1995-1997, with the 1995 F1 GTR taking victories in the FIA GT1 class and the prestigious 24 Hours of Le Mans. After the Le Mans win, McLaren commissioned five commemorative F1 LM edition road cars with more power and even less weight (680 horsepower and 2340 pounds).

Development work on the F1 began in 1990 before the supercar was officially launched on May 28, 1992. The first production model, which carried a price tag of $778,000 unadjusted for inflation, was delivered in December 1993. Only 106 F1s, in street, race, and prototype trims, were ever assembled from 1993-1998, ensuring its continued elevated status on the automotive market. In 2008, a pristine F1 was auctioned off for $4.1 million.

Given the illustrious status held by the F1, the original McLaren road car has left big shoes to fill. Its successor, the MP4-12C, is due next year so be sure to take a look at the newest supercar to come out of Woking.
