Smart Engine (side- view)

The sturdy frame above the Smart power-train assembly is formed by an aluminium profile, below it is the exhaust system. Apparently, this is designated as a crumple-zone. Therefore, a different material and the - albeit small- free area to the engine. An air-hose on the left leads from the air-filter box to the turbo-charger mounted on the engine. Mounted directly behind the exhaust-gas turbo-charger is the Lambda sensor. 04/10
