Packard Model 30 (series U)

The Packard Model 30 frequently also called Model U, was a four-cylinder car built in several series from 1907-1912. Together with the smaller Model 18 (1908-1912), it was Packard's last four-cylinder automobile. Model 30 was Packard's lone offering for 1907 and 1908. It established Packard as a luxury car maker, and was replaced by the Packard Six.

The Packard Model 30 was a four-cylinder car with both closed and open bodies. Prices at introduction started with $4200 for open models and went up to $5500 for the limousine and $5600 for the landaulet. A 1911 Four-door Landaulet cost $5,750. Standard equipment included oil lamps, a tool kit, and two extra demountable rims. The closed cars also included speaking tubes, adjustable ventilators, and a dome light that had a separate battery. There was a speedometer and an air-pressure gauge. Wheelbase was 123 1/2" for the standard chassis.

The Packard Model 30 had a water-cooled, four-cylinder, T-head engine delivering 30 hp (NACC) at 650 rpm. displacing 431.9 cubic inches (7078 cubic centimeters) with a bore 5 in (127 mm) and a stroke of 5.5 in (139.7 mm).

A plate clutch was blocked with the engine. Power was transmitted by a long shaft with universal joints to the three-speed sliding-gear manual gearbox with reverse. This was located in a housing at the rear axle which also contained the differential. The car used shaft drive from the beginning, although many other high-powered cars at this time relied on double-chain drive.

In 1909, redesigned linkage in the transmission made it possible for the reverse gear to be activated with the regular gear-shift. Since 1904, all Packards had had a separate lever for the reverse gear.
