Smart looks, rear-wheel drive handling.
Pricey, patchy quality, poor ride, not sporting, limited rear visibility.
CLC benefits from style overhaul, but ultimately lags behind its rivals in drive, performance and quality.
All the new engines bar the CLC 350 auto are cleaner and more fuel efficient.
Lowest running costs belong to the 120bhp diesel that averages a frugal 48.7mpg - 5.2mpg more than the old engine. carbon dioxide emissions are reduced to 152g/km, 12% less than before.
Fractionally less efficient is the CLC 220 CDI: the more powerful 148bhp returns 47.9mpg and emits 156g/km of CO2.
The most efficient petrol engine in the C180 Kompressor returns a fine 39.2mpg and emits 170g/km of carbon dioxide, while the substantially more powerful 182bhp version of the same supercharged 1.8-litre engine still averages a reasonable 38.7mpg while producing just 4g/km more.
Worst for costs is, naturally, the most powerful flagship engine in the range. The 268bhp drinks at a rate of 28.2mpg and emits 239g/km, well above the 225g/km £25 London congestion charge limit.
