System Coverage Summary

Spanning 122 pages, this official document details the core mechanical and electronic architecture of the 2008 Smart Fortwo 451. It delivers in-depth technical breakdowns of the M132 engine alongside the second-generation 5-speed automated manual transmission (AMT 2). You will also find comprehensive blueprints of the tridion safety cell design. Further sections outline the SAM control unit networking, map out the diagnostic CAN bus architecture, and detail passive safety features such as the airbag and restraint system layouts.

Technical Specifications Preview

Accurate reference values remain critical for effective maintenance and diagnostics. This section provides precise specifications for the compact drivetrain. Engine output is rated at 52 kW, delivering 92 Nm (68 lb-ft) of torque at 4500 rpm. Transmission oil capacity requires exactly 2.4 quarts (2.3 liters), while the integrated fuel distributor rail operates under a regulated pressure of 46 psi (3.24 bar). When handling advanced brake and high-pressure fluid systems, prioritizing workshop safety and referencing correct factory tolerances is essential to prevent equipment damage or personal injury. For example, brake bleeding data explicitly notes that the fluid changer filling pressure must never exceed 2.8 psi (2 bar). Finally, you get complete baseline figures for cooling system capacities and maintenance intervals to support long-term reliability on the shop floor.
