Smart Car Engine – Small But Has Enough Power

There is only one Smart car engine available in America and that is the 1.0L, 3-cylinders-in-a-line type from Daimler. It also has an engine block and valve head made out of aluminum with 4 valves per cylinder. The bore is 2.83 inches with a stroke of 3.22 inches. This engine is rated at 52 kW or 70 horsepower at 5800 rpm’s with a maximum torque of 68 lbs-ft at 4500 rpm’s. The oil capacity of this engine is 3.5 quarts and there is 4.5 quarts of coolant in its cooling system. The multiport fuel injection is the way it delivers the petrol to the cylinders.

To transfer this power to the rear wheels is a 5 speed automated manual single dry clutch plate transmission. The gear ratios are for first gear -3.308, second is -1.913, third is -1.258, fourth is -0.943 and fifth gear is -0.707. The reverse gear ratio is -3.231 and the final drive in the rear end is at -4.529.

The front axle suspension has a lower wishbone with McPherson Struts and an anti roll bar. The rear axle suspension is DeDoin with coil springs and telescopic shock absorbers.

The ABS braking system is of dual circuit design with tandem servo assistance. The front brakes are 11 inch discs and the rears are 8 inch drums. This system also has traction control and electronic brake assistance.

This is the breakdown of not only the Smart car engine, but the other main mechanical components that are all standard on this fuel efficient car.
