The 1937 Series 90 remained essentially the same as the 1934-36 cars. 1937 was the final model year for the
overhead valve V-16 engine. For the first time, hydraulic brakes (with a vacuum booster on the pedal) were used
on these cars. A stabilizer bar was added to the front suspension. A Handy oil filter replaced the Cuno
self-cleaning unit. A pressure cap was used on the radiator.
