Polaris Slingshot Three-Wheeler - Car and Driver (blog)
The Polaris Slingshot SL you see here is red, but base versions come in only one color: titanium metallic. One might call it gray, as in the gray area between cars and motorcycles, a regulatory DMZ where few dare to tread. Freedom-loving Texas, for instance, will happily let you park your helmetless carcass on a Hayabusa, but it blocked sales of the Slingshot on the logic that it has bucket seats and is thus not a motorcycle. Indeed, the Slingshot has waterproof seats, three-point belts, and forged aluminum roll hoops. It has a steering wheel and a five-speed manual transmission, with reverse. The view ahead is of two wheels sprouting from forged aluminum control arms, flanking a long hood that conceals a longitudinally mounted GM Ecotec 2. 4-liter four-cylinder. The back half is propped up by a single wheel shod with a 265/35R-20 Kenda car tire (base models get an 18-inch rear wheel and tire). 6 inches long and 77. 2 inches wide at the front, the Slingshot has some singular proportions. It’s nearly eight inches shorter than a Mazda MX-5 Miata and a couple of inches wider than a Lamborghini Huracán. Source: www.caranddriver.com
