Bugatti Royale 1926
The Bugatti Type 41, better known as the Royale, is a large luxury car built from 1927 to 1933 with a 4.3 m (169.3 in) wheelbase and 6.4 m (21 ft) overall length. It weighs approximately 3,175 kg (7,000 lb) and uses a 12.763 litre (778 cu in) straight-eight engine. For comparison, against the modern Rolls-Royce Phantom (produced from 2003 onward), the Royale is about 20% longer, and more than 25% heavier. This makes the Royale one of the largest cars in the world.
Ettore Bugatti planned to build twenty-five of these cars and sell them to royalty as the most luxurious car ever but even European royalty were not buying such things during the Great Depression, and Bugatti was able to sell only three of the seven made (six still exist, one destroyed in wreck).
