Technical specifications for a smart car

The Smart car is a hybrid electric-motor vehicle with a gasoline engine. Its performance has been rated against EPA CO2 standards by running idle exhaust tests and on-board diagnostics to monitor greenhouse gas emissions and gas-cap tests to ensure a vehicle's fuel economy is maintained. The car adheres to federal safety standards and passive safety regulations employed by Mercedes-Benz. As of 2010, there are a number of technical specifications associated with the standard Smart ForTwo Pure Coupe, Smart Passion and high-end BRABUS GmbH Coupe and Cabiolet.


The Smart ForTwo 2010 has three in-line DOHC (double-overhead cam) cylinder configurations with four valves per cylinder, variable-valve transmission (VVT) and an engine capacity of 61 cubic inches in both the Coupe and Cabriolet models. The rated output of the engine is 53kW/70 horsepower, at 5800 revolutions per minute, and has a five-speed AMT (automated manual transmission).

Fuel Economy and Performance

Fuel economy and performance are directly affected by the Smart car's weight; a heavier car has a lower mpg (miles per gallon) output. The kerbside weight for the Smart Pure and Passion Coupe is 820kg. The Passion Cabriolet and BRABUS Coupe are 840kg., while the Smart BRABUS GmbH Cabriolet is 860kg. Premium 91 octane gasoline is recommended for the electronic multipoint fuel-injection system that powers the vehicle. The Smart car's fuel tank capacity is 8.7 gallons with a 1.3-gallon reserve. The Smart ForTwo has a top speed of 90mph and can achieve 0 to 60mph in 12.8 seconds. The estimated city/highway mpg for the Smart car is 33/41, according to the Environmental Protection Agency's 2008 vehicle testing procedures as specified in the Code of Federal Regulations (see Resources).

Braking and Safety

The braking system in the Smart ForTwo incorporates a hydraulic dual-circuit braking system with ABS (anti-lock braking system). The electronic stability program eases uphill starts and distribution, and traction control with electronic brake assistance provides the driver with more control on the road during inclement weather. The Smart car's safety management system has advanced crash avoidance and crash protection systems, which adhere to federal safety regulations and passive safety standards developed by Mercedes-Benz, whose technical concepts have become an industry standard internationally: These safety features include seat belt details, driver and passenger airbags, defined crumple zones, deformable steering columns and a rollover bar.

Dimensions and Aesthetics

The Smart ForTwo's measurements are 106.1 inches in length, 61.38 inches in width and 60.71 inches in height, with less than 0.4 inches in difference between the Smart ForTwo Pure Coupe and the more expensive Smart ForTwo BARBUS GmbH, the latter being the slightly larger of the two. The body of the vehicle is aerodynamic, and it's possible to customise the shell design in a wide spectrum of colours and patterns through a Smart car centre.


The Smart ForTwo Pure Coupe starts at £7,793, the Passion Coupe at £9,093, the Passion Cabriolet at £11,043, the Smart BRABUS Coupe GmbH at £11,693 and the Smart BRABUS Cabriolet GmbH at £13,643, base price as of October 2010. These prices don't include any additional customisations or accessories.
