Sebring

The hard edges of the 2016 Audi R18 might be polarizing, but they still look good on the track during this test at Sebring.

The Ford GT sounds amazing in this clip of the future racer rumbling around Sebring during development.

Forty years ago, BMW scored its first victory at Sebring with the 3.0 CSL. Now it's preparing to return to the Florida circuit with a modern Z4 GTLM decked out in a throwback tribute livery.

Nissan's test of the new GT-R LM Nismo at the ultra-bumpy Sebring circuit was brought to a halt after 68 laps because of a problem "with the engine mounting."

Racing fans at Sebring are plenty used to seeing Honda powering into the winner's circle, the Japanese motor company having claimed class victories at the endurance race in Florida in 2007, 2009, 2011, 2012 and 2013. Those were all in the LMP2 category, but with the Twelve Hours of Sebring now part of the combined United SportsCar Championship, Honda is branching out into another class: Daytona Prototypes.

At last month's 12 Hours of Sebring, Audi raced its hybrid R18 e-tron quattro in the U.S. for the first and likely last time. Sebring is undergoing a change for 2014 where no Le Mans Prototypes (LMP) can participate. Audi has been involved in LMP races since 1999, including the historic 24 Hours of Le Mans, which we covered in-depth last year.

This year's 12 Hours of Sebring wasn't exactly a foregone conclusion because we're still talking about racing, and anything can happen when the speeds are as high as the adrenaline and the desire. But we're still talking about Audi bringing it's two top-spec racers – and its huge budget and its nearly neurotic attention to detail – to a race that it uses as a test bed for The 24 Hours of Le Mans and as a way to open the endurance racing season with a victory.

The 61st edition of The 12 Hours of Sebring is on, and Autoblog has come to central Florida with Audi to feast on jumbo boiled peanuts, pickled eggs and the final race for the LMP1 class at the oldest road course in North America. As Audi has been doing for more than a decade now, it's brought its latest endurance race car, the 2013-spec R18 etron quattro, to Sebring to begin testing for Le Mans.

Just when we thought the DeltaWing couldn't get any weirder, DeltaWing Racing Cars unveils a new enclosed version of the experimental racer. The coupe is set to bow at Sebring International Raceway this week, complete with an all-new tub to help it comply with 2014 LMP1 regulations. The new racer, to be campaigned without former sponsor Nissan, also features a new engine worked up by the minds at Elan Motorsports Technologies. The open-top machine will still get around the track thanks to a revi

We were baffled a few weeks back when the American Le Mans Series and Grand-Am Rolex Sports Car Series announced new classes that will make up their combined racing program in 2014. Gone from the list is the Le Mans Prototype class, otherwise known as LMP1. The LMP1 class has long been the top dog of endurance racing, both in Europe and the US, so we couldn't figure out why this newly minted racing series was jettisoning it like yesterday's donuts.

Legendary motorsports journalist and racing commentator, Chris Economaki, died late on Thursday evening at the age of 91.

We will cop to having arrived at work suffering from memory loss, but never from hitting a moose. At least not that we can remember, anyway.

Nissan took the new DeltaWing racer out for a quick parade lap at Sebring last week. The funky-looking car wasn't exactly tackling each apex at competition speeds, but the demonstration suggests development is on the right path. Nissan says the design weighs half as much as a typical competition vehicle and has half the aerodynamic drag as well, making it far more efficient. Likewise, the car requires less power to maintain the same level of performance (Nissan has fitted the DeltaWing with a tu

After dominating Le Mans-class endurance sportscar racing for years now, Audi is left with little to prove. Plus, with sister-company Porsche returning with an LMP1 program of its own, and Bentley reportedly considering the same, rumors have been circulating that the four-ringed automaker could quit while it's ahead. It's something that rivals old (like Peugeot) and new (like Toyota) were undoubtedly rooting for, but no such luck: Audi isn't going anywhere but the finish line.
