2018 Smart Fortwo Electric Drive Cabrio – Test Drive Review




The 2018 smart fortwo electric drive cabrio really shines with the top down in sunny Southern California

As the world continues the transition to electric drive, we’re finally beginning to get some variety in the form factor of the EVs available.

Tesla, of course, has led the way by not only offering long range EVs, but also giving buyers an opportunity to get an electric vehicle that was something other than a small hatchback, designed primarily for city use.

Now, other OEMs like Jaguar, Mercedes and Audi are following suit, and will soon bring long-range, all electric crossovers to their showrooms sometime in 2018 & 2019. Electric vehicle advocates have long argued that slow EV sales were more of a product of lack of variety in vehicle types available, than that of a lack of demand.


Test Driven In San Diego

While that all may be true, it doesn’t mean that the small micro and mini cars still aren’t a great platform for electric drive.  In fact, a few months ago it was announced that smart was abandoning internal combustion completely for the US market, and would only be selling electric drive vehicles here starting in 2018. Recent rumors have MINI also considering the same move to selling only electric cars in the near future.


The driver’s display can toggle to show different information. Here it’s showing the trip and total miles, as well as the distance to empty.

While it’s undoubtedly true that inhabitants of European cities have embraced micro cars more than their US counterparts, there’s definitely a market here for these zero-emission runabouts. Cities, for instance, could potentially save a lot of money on fuel and maintenance, while reducing air pollution if they used these cars for municipal fleets of parking and code enforcement officers, and inspectors like Housing and Board of Health.

smart cars have always been great city cars, and the electric drive smarts are no exception. However, with a short 58-mile EPA range rating (57 miles for the cabrio) the smart electric drive is first and foremost a city car, although some suburbanites that do not have a demanding driving routine may also find the range acceptable for their needs.

Besides the fact that smart is transitioning to electric-only for the US market, the other big news for the brand is that they are now introducing the new smart fortwo electric drive cabrio for 2018. The new ragtop version of the fortwo is the only all electric convertible available for sale today.

I was invited to the Press Drive hosted by Mercedes in San Diego this week to get a chance to kick the tires, roll back the roof and give the new smart cabrio an extended test drive around the city. I’ve driven earlier versions of the electric smart, so I somewhat knew what to expect, and what I was hoping had been improved.

First off, I noticed smart had increased the maximum charging rate from 3.3 kW to 7.2 kW, a welcomed move. Honestly, I can’t understand why any BEV or even PHEV with a battery larger than 10 kWh that doesn’t accept at least 30 amps at 240 volts. Yes, I know it adds cost, but the faster charge rate increases the utility of a BEV immensely, and allows the PHEV owner to drive more miles on electricity, which is the main purpose of getting a PHEV in the first place. That said, I’m happy to report that smart is finally onboard with a proper charge rate for the new smarts. A DC Fast charge option isn’t available, but honestly, with only a 17.6 kWh battery, DC fast charge wouldn’t really offer enough of an improvement in charge time to warrant the extra cost. The battery employs a liquid thermal management system for optimum performance and to prevent early capacity loss from possible overheating.


The power meter displays the state of charge as well as the current level of power delivery or energy regeneration.


The optional 7 inch touchscreen center display is a nice feature, but it can be hard to see with the top down and the sun shining in.

The power meter which displays the state of charge is located on the left side of the driver’s display, next to the A-pillar. This meter also displays how much power is being consumed, as well as how much energy is being recuperated with regenerative braking. I definitely like the new interior layout, it’s an improvement from the previous generation of smart electric drives that I have driven.

The standard 3.5 inch center display shows information including:

  • Display of the battery state of charge
  • Extended display of the charging rate
  • A detailed “Eco Score” to let the driver know how efficiently they have been driving
  • Energy flow display including auxiliary energy consumers with digital values
  • The pre-conditioning function display and departure time settings

Customers that opt for the optional smart Media-System get a 7- inch color touchscreen display with additional functions that include:

  • The current range can be considered in the selection of navigation destinations to assist in trip planning
  • Charging stations can be added as intermediate destinations
  • Navigation to the nearest charging station when the first battery reserve warning
  • Charging station search based on POIs on the SD card
  • Live traffic information provided by Tom Tom

The seats are comfortable and supportive

The miniscule 22.8 ft turning circle is perfect for negotiating tight spaces and making U-turns, and the ride quality is pretty good for a car with such a short wheelbase. Yes, you can feel the bumps more than you do with larger, heavier vehicles, but the suspension does a decent job considering the task at hand. The cabrio’s power roof slides back on a track and can be opened at any speed. The tracks lock in place above the side windows and can be removed and stored in a compartment in the rear hatch, giving the car a true convertible experience.

On the road the smart fortwo electric drive cabrio performed pretty well. It won’t win too many drag races with its 11.7 second time from 0-60, (11.4 for the hardtop version) but it didn’t feel that slow either. Perhaps it feels quicker than it really is because of the instant responsiveness of the electric motor, which has more power for 2018.

There’s now 80 horsepower (up from 74 hp) and 118 lb-ft of torque (up from 96). It did have plenty of power to get up to highway speed, but after about 65 mph the power really tails off.  The car is limited to 81 mph, (up from 78 mph in previous years) and that’s probably a good thing as once you get over 75 mph, the small, tall frame gets pushed around a bit by the wind. However, top speed and high-speed highway driving obviously isn’t what smart is all about.


There’s a storage compartment on the rear hatch door that holds the two removable roof bars. These bars provide no structural support, so removing them doesn’t compromise safety.

Where the smart really shines is driving around town and darting through traffic. It’s about urban personal mobility, and with electric drive and now a cabrio version, that means eco + fun can be had for $28,100 ($23,900 for the hardtop) before incentives. Factoring in the federal tax incentive, and state rebates here in California, the hardtop smart fortwo electric drive can be had for a starting price of only $13,900 and the cabrio for only $18,100.

The regenerative braking is noticeable when you let up on the accelerator, but it’s not nearly as strong as a Tesla, BMW i3 or Chevy Bolt. The regen is also blended into the friction brake pedal, so when you depress the friction brakes, the amount of energy regenerating increases. Also new for 2018 is an ECO mode, Android Auto (with the optional Media System), a slightly larger battery (3 more cells for a total of 96) and a standard eight-year battery warranty.


Smart Fortwo Electric Drive Cabrio

The smart fortwo electric drive isn’t going to be for everybody. However, it is a pretty nice option for those that want an EV and don’t have very demanding driving needs. It’s perfect for inner city driving, it can fit in the tiniest of parking spaces and if you get the cabrio you can do it all with the sun shining down on you. I don’t expect smart to sell too many of these in cold weather states or in rural areas, but here in sunny Southern California I can definitely see a market for them, especially when considering the sub-$20,000 price tag after incentives.

Well, looks like the first Renault made it to the US since Decades. (The new Smart is in fact a Renault Twingo and the electric Engine and Electronics are developed out of the Renault Zoe.)
This is also the reason why you don’t see accepting a higher Charge Rate as like the Zoe the Smart is using the Engine and Inverter-Electronics as “Charger”, Renault is selling that as Chameleon Charger as it widely adopts from 1-Phase 8Amps up to 3-Phase 32Amps. So it is not using a dedicated piece of Hardware for Charging. However as said the Engine and Electronics are optimized for 3-Phase Charging which explains the limitation to 32Amps that simply can’t be exceeded.

The Smart ForFour is the same platform as the Twingo. The Smart ForTwo isn’t (there’s no two-seater Twingo).

The ForFour and ForTwo use the same platform. The ForTwo just uses a shortened version. And it is not correct to say that it is the “Twingo” platform since it was developed for both cars (Twingo and Smart) and they came out at the same time…

The ForTwo ED was the best-selling plug-in in Germany in November, with 621 units (Coupe + Cabrio).
The ForFour ED did also well, with 187 sales.

(https://www.kba.de/SharedDocs/Publikationen/DE/Statistik/Fahrzeuge/FZ/2017_monatlich/FZ8/fz8_201711_pdf.pdf?__blob=publicationFile&v=2 in German)

But if they costed just a couple thousand euros/dollars more then the ICE versions (before subsidies, which should be totally possible when really mass produced and honestly priced), instead of about 10,000 €/$ more…
How many could they sell then !?!

Don’t see any inventory on the 2018s yet. I wonder if any will be available before end of year.

“with only a 17.6 kWh battery, DC fast charge wouldn’t really offer enough of an improvement in charge time to warrant the extra cost”

This is entirely wrong. My SparkEV capacity is now about 17.5 kWh, yet I can drive 300 miles a day to/from LA area. Even without such long drive, I can confidently go further than 30 miles from home since I know I can charge at DCFC (albeit, wait for Bolt) to get home with only 15 minutes charging. Even 60 kWh EV without DCFC (eg. Bolt wihtout DCFC option) isn’t as useful as 17.5 kWh EV with DCFC.

I have the 2016 Smart gas version here in LA, I use it more than my Tesla, looks a bit silly but usability and ease of parking is great. I think only after you have one, you understand and get it more.

cost and efficiency are great compared to most electrics. The faster On Board Charging is a good move.
The new 4 seat will also increase it’s market. A nice around town car.

I wonder when we might have them available in Arizona?

I’m obsessed with this car…I’ve never been in one…but I read up on it every day…try to buy a used one and they had sold it…can’t afford it but im gonna get it…lol
