Vuhl 05
The Mexican-made Vuhl 05 ($84,000) — a barely 1,500 pound, 285 horsepower two-seater — seems bred for the track day. An extremely-lightweight steel, aluminum, and plastic open-top body, and a well-tuned two-liter Ford EcoBoost four-cylinder engine, make this exactly the sort of ride we would want to whip around a track for a weekend. With a max speed upwards of 150mph, and the capability of turning 0-62 in only 3.7 seconds (not to mention four-wheel disk brakes, a six-speed manual gearbox, and some fairly-large Michelin tires) you might embarrass a couple Porsche drivers. And, because it's perfectly street legal, you wouldn't even need to trailer it. Available spring of 2014.
