has just unveiled an even more powerful version of their X-Bow. As they work to fight off new competitors such as the BAC Mono, the company has just unleashed the X-Bow R. The R features an Audi
2.0-liter TFSI gasoline engine that's been equipped with a larger turbocharger, higher performance fuel injectors, and a reworked ECU. The result? The four-cylinder now produces 295hp and 295 lb-ft of torque. The standard X-Bow, just for comparison, has 237hp.
