Nissan's DeltaWing goes for a ride at Sebring

The Nissan-powered DeltaWing race car was on-hand for a few laps at Sebring this weekend, and the funky-looking speedster made it around the 3.7-mile track without incident. Granted, it was at about half race speed, but it was good to see the Nissan out on four wheels— narrow as some of those wheels might be. The DeltaWing sports a direct-injection, 1.6-liter turbocharged Nissan engine making about 300 hp.

Rolls-Royce Ghost V-Specification dialed up to 593-hp

Just before a refreshed Rolls-Royce Ghost debuts at the Geneva Motor Show in March, the British automaker has rolled out a performance edition of its "entry level" sedan with 593-hp underhood. The standard Ghost sedan wasn't exactly short on power until the announcement of the V-Specification version -- the company's 6.6-liter twin-turbocharged V12 engine produces 563-hp and 575 lb-ft of stump-pulling torque in standard form. Yes, gone are the days when Rolls-Royce declined to disclose exact power figures and simply listed their powerplants' output as "adequate." Now Rolls-Royce is forced to compete in this cutthroat market with its performance stats, it seems.

Renault to unveil Alpine-branded concept car at Monaco GP

Renault is set to unveil an Alpine-branded concept car at this weekend's Monaco Grand Prix. The A110-50 – so named to commemorate the fiftieth anniversary of the oh-so-pretty A110 rally car – is clearly a development of the 2010 DeZir concept car although with only one leaked image to analyze, it's difficult to know by what amount it has changed. Clearly it has been subjected to the addition of a myriad of additional details, surfaces, inlets, outlets and various pieces of racing addenda however that, on the little evidence we have, appear to have added drama to the detriment of the refreshingly non-aggressive nature of the DeZir.
