This weekend the principality of Monaco hosted the bi-annnual Historic Grand Prix of which a full report will be published here later in the week. As part of the support program, Audi show-cased two of its Auto Union 'Silver Arrows' and also gave the all-new R8 GT its public debut. Limited to just 333 examples, it is based on the already very potent V10-engined R8. Audi's engineers have managed to increase the car's capabilities considerably by lowering the overall weight and boosting the engine's power. Around 100 kg has been shaven off by using thinner glass and exotic composites for a variety of panels. The direct injection V10 engine has been tweaked to produce a hefty 560 bhp compared to 525 bhp in the 'standard' model. The exterior was also refined to produce more downforce without raising drag. One of the most visible changes is the addition of a carbon fibre rear wing. Upon request the Audi R8 GT can also be equipped with a roll bar and other racing amenities like a fire extinguisher.
Canadian auction house RM were present at the Monaco Historic Grand Prix for the first time with a spectacular result. The site of the auction was the spectacular Grimaldi Forum at the bottom end of the track near the entry to the tunnel. Over 33 million Euro ($45 million) worth of cars changed owners on Saturday evening. The sale was topped by a superb Ferrari 400 Superamerica Cabriolet, which reach a hammer price of 2,800,000 Euro ($3,799,600); a record for a Superamerica. This particular example is one of six produced and was completely restored before being shown at the 2009 Pebble Beach Concours d'Elegance.
As mentioned earlier a detailed report of the event and the various auctions will be published later this week, illustrated by a sparkling gallery with numerous pictures of all eight classes.
