Why it matters
The 46S was the supercharged version of the 5.4-litre Type 46 luxury chassis. Only 18 were made against 444 standard Type 46s, which makes it one of the rarest specifications among Bugatti's large touring cars.

History
The Type 46 appeared at the end of 1929 as a large touring chassis with a 5359 cc single-overhead-camshaft eight and a three-speed gearbox in the rear axle. From 1930 to 1933 Bugatti offered the 46S with a Roots supercharger, raising output from about 140 bhp to about 160 bhp.

06Reference
Identification guide
How to tell an original from a replica or later conversion.
A genuine 46S has the Roots supercharger that the standard Type 46 lacks. Both types use 20-inch wheels, with cast alloy vane-type wheels on later cars, a 3.5 m wheelbase and a three-speed gearbox in the rear axle with a central ball-type lever.
