This 2004 Smart Roadster packs a tiny but spirited 698cc 3-cylinder engine, running roughly 800kg on street trim. Unique to this little machine, each cylinder has 2 spark plugs, giving it a distinctive firing setup and spirited drive.
Our customer came in for a Stealth 4.0 Controller fitment, enhancing throttle response and control. The car is also booked in for a custom dyno tune in April, and we can’t wait to see it in action on the dyno!
Even small engines can deliver big smiles — and with the right tuning and upgrades, this Smart Roadster will be no exception.
Stay tuned for the dyno results and performance gains! 🚀
