2013 Porsche 911 RSR makes official debut

Porsche is ready to go racing in 2013, showing off a new 911 RSR today that is scheduled to compete in several endurance events this year. Based on the current 991 911, the new RSR will compete in the 2013 season of the World Endurance Championship and the 24 Hours of Le Mans. It will not, however, make an appearance in a North American racing series this year.
The 2013 version of the racecar has increased in wheelbase by some four inches, features a new wishbone front suspension in place of the last-generation's McPherson strut setup and boasts a new, lightweight six-speed racing gearbox. The engine, meanwhile, is an "optimized" version of last year's car, a 460-horsepower 4.0-liter boxer six-cylinder. Extensive use of carbon fiber and polycarbonate windows help the RSR shed weight, and Porsche has also balanced the weight more evenly with a lower center of gravity.
Porsche has thoughtfully dedicated some space to celebrate the 911's 50th Anniversary, with the number 50 clearly visible in the top-down view of the RSR, as well as along the doors. Scroll down to read the full Porsche press release, below.

Historic race cars highlight the RM Sotheby's 2023 Le Mans sale

Auction house RM Sotheby's is celebrating 100 years of the 24 Hours of Le Mans by organizing a big sale on the day before the race. The cars scheduled to cross the auction block have all spent time on the track, and the catalog shows how racers have evolved since the 1930s. Browsing through RM's auction catalog is like taking a five-minute course in the history of racing. The oldest car is a 1932 Aston Martin Le Mans 'LM8' that's had a remarkable life. It was developed and built for competition and entered in the 1932 24 Hours of Le Mans by the Aston Martin factory team, where it finished seventh. It was ultimately sold to a private owner but it survived, which shouldn't be taken for granted: teams often destroyed obsolete race cars, and the list of special vehicles that didn't survive World War II is longer than you'd think. Paul Sykes bought the car in 1955 and used it as his daily driver. Imagine walking out of a shop in a British village in the 1960s and finding a 1932 race car parked next to your Mini. Sykes ultimately bought another daily driver, but he kept the Aston Martin for a total of 55 years. The second-oldest car is a 1936 Delahaye 135 S with a body by coach builder Pourtout. RM notes that this is one of the most significant pre-war competition Delahaye models and adds that it finished second in the 1938 edition of the 24 Hours of Le Mans. It continued racing until 1956 and then spent several decades hidden in storage. It was fully restored in 2005, and it's now eligible to compete in historic races such as the Mille Miglia and the Le Mans Classic. Restoring it was easier said than done: the car was rebodied twice before being tucked away. None of the cars crossing the block were built in the 1940s, so we skip ahead to the 1950s with a 1954 OSCA MT4 by Morelli. It's one of 72 built, according to RM, and only 19 of those were fitted with the twin-cam, 1.5-liter 2AD engine. It raced at Le Mans in 1954 but ended up disqualified following an accident. Another highlight from the 1950s is a 1958 Lister-Jaguar 'Knobbly' finished in yellow and green. We said that all of the cars crossing the block have spent time on the track, but that doesn't mean they were built to race. The 1963 Ferrari 250 GTE 2+2 Series III is a street-legal model, yet it's included in the auction because it was used as a safety car during the 1963 edition of the race.

Porsche Macan to get four-cylinder engines

Porsche hasn't offered a four-cylinder engine since the 968 went out of production in 1995 - the better part of two decades ago. There'd been talk of a four-pot Boxster or an even smaller model to slot in below it, but while the latest intel indicates that Porsche is moving ahead with its four-cylinder plans, it's a different kind of vehicle that will get it first.
That, of course, would be the new Macan. Just revealed a few weeks ago at the LA Auto Show, the Macan crossover is being launched with a pair of twin-turbocharged V6 engines (a 3.0 with 340 horsepower and a 3.6 with 400 hp) and a six-cylinder turbodiesel with 258 hp. But smaller engines, according to emerging reports from Autocar and Auto Express, are on their way.
Word has it that Porsche is preparing a 2.0-liter turbo four with 280 horsepower and a diesel with the same displacement and cylinder count, engines that will power new entry-level Macan models that will slot in beneath the existing Macan S, Macan S Diesel and Macan Turbo. While the diesel is tipped to be ported over from the Volkswagen parts bin, the four-cylinder gasoline engine is said to be under development by Porsche itself, which could mean it will have a boxer layout.
