Smart City (W450) 2000-2004 0.6 Turbo 61bhp Stage 1 Eco remap figures
The Stage 1 Eco map for the Smart City 0.6 Turbo 61bhp (2000-2004): 79bhp and 117Nm expected from a standard 61bhp and 88Nm, up to +18bhp and +29Nm. It keeps most of the Stage 1 gain (Stage 1 is 85bhp and 120Nm) and is tuned with economy in mind: the choice if you want the performance and care what each tank costs.

Stage 1 Eco remap figures
Stage 1 Eco is performance with economy in mind. It keeps most of the Stage 1 gain, so the car still pulls well, but the map is shaped for efficient, relaxed driving rather than flat-out output. It is above the standard figures. We don't quote mpg, because economy depends on the car and how it is driven.

Who is the Stage 1 Eco map for?
- Drivers who want a quicker, more responsive car, tuned with economy in mind.
- Daily drivers who want strong mid-range pull without giving up efficiency.
- Anyone who would otherwise take full Stage 1 but cares what each tank costs.
How Stage 1 Eco compares with Stage 1
Full Stage 1 on this Smart City is expected to give 85bhp and 120Nm (+24bhp, +32Nm). The Stage 1 Eco keeps about 75% of that power gain and 91% of the torque gain, so you get 79bhp and 117Nm: 6bhp less and 3Nm less than Stage 1, with the map shaped for efficient, relaxed driving, so it suits you if you want the pull and care about running costs. Both sit above the standard 61bhp and 88Nm.
What this means for your City
On a turbocharged petrol engine a remap adjusts boost, ignition timing and fuelling together, so both power and mid-range torque rise and the car pulls harder out of corners and junctions.
The ECU recorded for this variant is a Bosch MEG1.0/1.1. Older engine management is simpler to work with, but age matters: worn sensors, leaks and tired components can hold back what a remap delivers, which is why we run a diagnostic check first.
We remap at our Belgrave Gate workshop in Leicester, or at your home or work within 30 miles, and every job starts with a diagnostic check.
Please note: these are expected figures, not guarantees. Real results vary with the condition of the vehicle, the ECU software version, fuel quality and the hardware fitted. Some options - including Stage 2 and anything that needs extra hardware - are for off-road or competition use only. We check every vehicle first and confirm what is achievable before any work starts.

Stage 1 Eco questions
How much power does the Stage 1 Eco map give the Smart City 0.6 Turbo 61bhp?
We expect 79bhp and 117Nm against 61bhp and 88Nm as standard: up to +18bhp and +29Nm. These are expected figures, and we confirm what is achievable on your own car after a diagnostic check.
How does Stage 1 Eco differ from Stage 1 on this engine?
Full Stage 1 is expected to give 85bhp and 120Nm. Stage 1 Eco gives 6bhp less and 3Nm less, in exchange for a map shaped with economy in mind. It still sits above the standard figures.
Is Stage 1 Eco or the Eco map better for me?
Choose Stage 1 Eco if you want the performance (79bhp and 117Nm) and still care about running costs. Choose the Eco map (77bhp and 116Nm) if economy matters more than pace.
Will the Stage 1 Eco map save fuel?
It is tuned with economy in mind while keeping most of the Stage 1 performance. We do not quote mpg figures, because economy depends on the car, its condition and how it is driven.
Do I need to tell my insurer about a remap?
Yes. A remap is a modification, so you should declare it to your insurer.
