When it arrived in the UK, the Smart Fortwo CDI had the dubious honour of being one of the least powerful cars to be launched for many years.

Its 45bhp 799cc three-cylinder diesel engine didn’t have much in the way of performance, but it was a car aimed at urbanites and had ultra-low CO2 emissions of 89g/km.

It took almost 20 seconds to reach 62mph from rest and like all Smart Fortwo models was limited to 85mph – not that a limiter would have to work hard in this car.

While its lack of outright speed wasn’t much of an issue around town, Smart has managed to carry out an engine upgrade that now makes the car less painful on the motorway.

Even better news for fleet operators and drivers is that the 9bhp increase has not had an adverse affect on CO2 emissions or fuel consumption.

While 9bhp might not sound like much, for the Smart Fortwo CDI it’s a 20% increase, while torque is also increased by 15lb-ft to 96lb-ft.

It’s enough to shave almost three seconds off the car’s 0-62mph time.

Criticism of the sequential manual gearbox on the Smart and other small cars has been well documented, and here some of the complaints still remain, although this is the best version we’ve seen yet.

When left to its own devices in automatic mode, it can seem slow-witted when changing up through the gears.

The diesel Smart has an exceptional official fuel consumption figure of 83.1mpg on the combined cycle.

I have no doubt that in certain conditions that would be achievable, but many of the 600 miles or so I spent in the car were on the motorway, and typical fuel consumption for motorway driving was somewhere in the mid-50s. 


The Smart is best as a pool car or urban runabout, but doesn’t look so clever now hybrids match its low CO2 and other four-seat small cars can match it on overall costs.

    The only problem with Hybrids, is that they all cost a significant sum of money to purchase, and for the majority of vehicles sold, including the latest Smart Electric, you have to rent the batterys on a monthly rate.

    I own a Smart Cdi, and motoring does not get any cheaper, a regular 70+mpg, and even 80mpg if your careful.

    Once out of warranty,you can source your own parts, which are not expensive, and servicing is very affordable with an independent specialist.

    The big plus, is that you own the battery, and a new one costs £47 not hundreds.

    Recently had a smart fortwo cdi on a 63 plate, it's great on diesel and best mpg after three fill ups has been 84 mpg with the worst being 67 mpg and last being 78.5 mpg. The best mpg was achieved over a 221 mile run (from being brimmed) over a number of days including a 40 mile (roughly) motorway trip at the national speed limit and lots of smaller stop/start trips. Great little car, totally adequate power etc for town driving, folks just need to remember its a 54 bhp diesel chugger with similar performance to a narrowboat not a golf gti. Mines been purchased to save me £ which it is doing so, more mpg than my 7 seater, less wear on my 7 seater etc... The Smart is exceptional and there's a knack to get the best out of its mpg, using the paddle shift gears from about 2100 rpm with help for changes up.
