I thought mine was a 3rd Gen 451. But then I ran into a page in a service manual that showed two gens for the year. I think I saw a post mentioned that the 3rd gen was delivered later in the year.

How can I find out which Gen I have?

The ED2 (Tesla battery) was from 2009 to 2011. The ED3 (battery by MB subsidiary) was 2012 and on, starting with the 2013 model year.

Only the 2011 version ED2 ever got into public ownership. The rest should have been scrapped, though you never know how many avoided the crusher.

Your 2014 is an ED3. Per the manual you're reading, your correct specs are on the left. :)

The three phase program ended with the final 451 electric drive (2013+), so the 453 electric drive is just the 453 electric drive.

Perhaps this is why Kane from Evilution refers to the ED2 as the ED Gen 2 and the ED3 as the Gen 2, mk 2...less confusion?

I thought the 3rd gen started in 2013. The easiest way to tell if you have one or the other is the top speed. I believe the 2nd gen tops out around 65mph. The 3rd gen tops out around 80mph.

I got mine up to 70 mph on a trip on the highway. That was the speed limit so I didn't go any higher. 80 mph, I dunno if I have the guts to go that fast in it. hehe

Thanks for the info.

From Wiki:

Smart electric drive

Third generation Smart electric drive
Main article: Smart electric drive
An all-electric version of the Fortwo, the Smart Fortwo electric drive, began development in 2006.[37][38] Field testing began in London with 100 units in 2007, and the second generation, with a total of 2,000 units, was introduced in 2009 and available in 18 markets around the world for leasing or through the Car2Go carsharing service in San Diego and Amsterdam.[14][15][39][40] Production of the second-generation Smart Fortwo electric drive began in November 2009 in Hambach, France. The Smart EDs have a lithium-ion battery provided by Tesla Motors with capacity of 14 kilowatt-hours (50 MJ). The range of a fully charged battery is up to 135 kilometres (84 miles) under the New European Driving Cycle (NEDC) cycle.[41][42] The U.S. Environmental Protection Agency's official all-electric range is 63 miles (101 km) and rated the Smart ED with a combined fuel economy of 87 miles per gallon gasoline equivalent (mpg-e) (2.7 L gasoline equivalent/100 km; 104 mpg-imp gasoline equivalent).[43]

The third-generation Smart electric drive is scheduled to be launched in the U.S. and Europe by the second quarter of 2013 and Daimler AG plans to mass-produce the electric car with availability in 30 markets worldwide.[15][44] The third-generation Smart electric drive was unveiled at the September 2011 Frankfurt Motor Show.[45] Key differences with the second-generation model include a more powerful electric motor, which improves acceleration and top speed, a new lithium-ion battery pack that will allow to increase the range to 140 kilometres (87 mi), and an option for quick-charge will be available.[15][45]

140 kilometres (87 mi)
Oh man.... I thought I was only to get 68 miles. I haven't seen 87 miles yet on a full charge. ugh!

That would mean I'm only getting about 77% of the max range when I see 65 miles at full charge. I will have to look into this. 80% is the guarantee with warranty, correct?

Thanks for the info.

Correct? - unfortunately no.

Wiki is not always right - the EPA rating for the U.S. Gen 3 (MY14) 451 ED was 68 miles as posted to the Monroney sticker.

Generally, you don't need to run the battery down to near zero (when the warning messages start and you go down to one bar on the power indicator) to get a good range estimate - and don't trust the "range remaining" indicator - it is usually very conservative especially in warm weather. Instead, just reset the trip odo and use the SOC gauge. For example, yesterday, I drove about 36 miles over typical conditions and terrain with the gauge going down to 60 percent. That would correspond to 90 miles per charge. But the range left indicator showed, at that point, only about 35 miles left or about 70 miles total range.

Just like the fuel economy ratings in IC engine cars, the EPA range rating is conservative if the car is driven carefully for economy in good weather. In the case of the new Smart ED, it is too conservative except in well below freezing weather.
