74 hp increased to 80 hp
96 lb-ft increased to 118 lb-ft
On-board charger increase from a 3.3kW unit to 7kW unit should in theory make charging faster. However if you are using the standard charger that came with the vehicle here in North America which is 110v input, this makes no differences as the output of that charge is not even close to 3kW.
With the new motor, increased performance, but the same battery, it is no surprised that the RANGE of this vehicle is LESS then the previous gen.
Sure its a better design car, the previous generation (which I am still driving) is a go kart, bumpy, stiff, and in many ways, pretty outdated design.
However with the increased MSRP, less incentive from Mercedes (at the moment), even with the increased MTO incentive (in Ontario), it's still hard to convince on getting the 2018 Smart Electric.
The most important is the RANGE! that is the number ONE issue with electric cars and smart did not just not looked into the problem, with the new motor but keeping the same battery, they have made it worst.
