Re: Smart injection
My engine started as a 45kw (61hp) model, these were prone to premature faliure, believed to be caused by the lack of an oil cooler, use of inferior oils (fully synthetic is a must), oil change intervals that were too long, piston design (possibly), high gears that are way too high in ratio and result in serious lugging by poor drivers and also harsh city use.
Mine has had a thermostatic oil cooler added.
Smart had oil coolers, shorter service intervals, Shorter top gear ratios and possibly different pistons in the higer spec engines (Brabus & Roadster) and these were not so prone to faliure despite making 20-40hp more! 33-66% more hp!!!
