fortwo cdi improved for 2010 - Smart Car of America Forums : Smart Car Forum

We may never see it here, but it's fun to watch the developments over the pond. That's some serious torque for such a small engine and puts the gas 1.0L to shame! It could probably climb some decent hills in 5th with no down shifting.

The FINANCIAL - smart fortwo cdi: 21 percent more power for the CO2 champion

"Its reengineered diesel engine now has an output of 40 kW/54 hp – seven kW or 21 percent more than its predecessor. Moreover, the new three-cylinder engine delivers maximum torque of 130 Newton metres [96 lb/ft] (an increase of 18 percent). This makes the car that is brimming with lifestyle appeal even more agile and fun to drive. Thanks to the power boost it now sprints from 0 - 100 km/h in just 16.8 seconds.

However, the increased liveliness does not affect the outstanding fuel consumption and emission figures of the trendy two-seater car. The combined fuel consumption still stands at 3.4 litres per 100 kilometres [~70 US MPG] and the extremely low CO2 emissions of just 88 g/km mean that the smart fortwo cdi is still the CO2 world champion among all production cars with combustion engines.

The 21 percent power increase is primarily realised through modified pistons in conjunction with adjusted injection and charge pressure parameters. Furthermore, thanks to the increased torque it was also possible to lengthen the gear ratios of the third and fourth gears by ten and eleven percent respectively, and to lower the shifting points in the automatic programme. This reduces the rpm level in speed ranges used particularly frequently – with benefits in terms of fuel consumption and noise level. The smart fortwo cdi is equipped with a closed diesel particulate filter and emissions are below the limit values laid down in the EU5 standard."

I can only assume thanks to all of Californias "leadership" we will never see it

I wonder how close the EU5 standard is to US EPA and CARB regulations?

EU 5 treates diesel engines more favourably than gasoline engines for PM and NOx, so it's not even close to USA standards.

You'd think that, considering the cdi's stellar performance with respect to CO2, CARB might be willing to compromise a bit on PM and NOx. After all, isn't global warming supposed to THE huge environmental threat? Surely, EU 5 would be clean compared to what was acceptable to CARB a few years ago.

Seriously, I misread it and thought the title of the thread was "fortwo cdi APPROVED for 2010"

My bad, but then I feel lucky to be able to post here on SCOA. After all, I AM a Panda and we're not known for our reading, comprehension or typing prowesses.....
