Sales dropped by 37 percent in 1907, an indication to Henry Leland that Cadillac should focus more heavily on developing multi-cylinder cars. The decline in sales was only temporary, as an ambitious Cadillac salesman in London, England named Frederick S. Bennett aided in reversing Cadillac's slump. He had been importing Cadillacs into Europe since 1903 and saw an opportunity to showcase the car's potential by entering three examples in Sir Thomas Dewar's annual trophy event. The three cars were disassembled, the parts shuffled, and then reassembled to new. This was overseen by the Royal Automobile Club. After the three cars were put back together, even using 89 parts from stock to prove interchangeability, they started and were drivable. This demonstration of interchangeability, plus being awarded the Dewar Trophy, gave the Cadillac marque instant worldwide recognition and spawned the slogan 'Standard of the World.'
The Cadillac Model S was introduced in 1907 and in 1908 the wheelbase was extended to 82 inches with the overall length of the car being 10 feet and one inch, and fitted with full running boards that replaced the step plates. Standard tires were 30-inch X 3-inch. The single-cylinder engine had a cast-iron cylinder, copper water jacket, a 98.2 cubic-inch displacement, and 10 SAE-rated horsepower. It used a Planetary transmission with two forward gears, one reverse, a disc clutch, a spur gear differential, and a chain drive. Mechanical brakes on two wheels provided the stopping power, contracting on inboard drums.
The Model S had a factory base price in the mid-to-high $800s, earning it the least expensive model within the Cadillac lineup. Other 1908 Cadillac single-cylinder models included the M and the T. The Model M was a two-passenger delivery vehicle and the Model T, with prices that ranged from $1,000 to $1,350, was offered as a coupe, victoria tourer, and St. Line Tourer. The coupe had seating for two, while the other two body styles had seating for four. All three of those body styles had two doors.
The 1908 Model G and Model H were four-cylinder models. Cadillac produced approximately 1,030 vehicles in 1907, 2,377 in 1908, and 5,903 vehicles in 1909. Cadillac consolidated its lineup in 1909 with the Model 30, a four-cylinder model that would power Cadillacs through the mid-1910s when the V-8 engine was introduced in 1915.
