The Volkswagen Beetle – The Peoples Car
In 1967, the car appeared similar to earlier models but much of the drive train was noticeably upgraded. Some of the changes to the Beetle included a bigger engine for the second year in a row. Horsepower had been increased to 54 hp. Top speed was 81 mph. On US models, the output of the electrical generator was increased from 180 to 360 watts, and upgraded from a 6-volt to a 12-volt system. The clutch disc also increased in size, and changes were made to the flywheel, braking system, and rear axle. New standard equipment included two-speed windscreen wipers, reversing lights, a driver’s armrest on the door, locking buttons on the doors, sealed-beam headlights, and a driver’s side exterior mirror.
In February 1967, inventor Don P. Dixon of San Antonio, Texas filed and was ultimately granted a patent for the first air conditioning unit specifically designed for the Beetle, which were soon offered by US dealerships.
