SIM-WIL: SIM-Drive’s 351KM-range EV with 5.4 Second 0 – 100KM/H Performance

Posted by Stephen On Thursday, March 29th, 2012

351 KM (218 miles) of range, and 0 to 100 kilometers per hour in just 5.4 seconds. And there’s more: On the outside it’s a compact car (“B segment” in Japan) but it has the interior space of a large executive sedan (“E Segment” in Japan).

What is it? It’s the SIM-WIL.

Regular readers will recall the previous prototype from SIM-Drive — the SIM-LEI that I wrote about last year. The SIM-WIL is the latest iteration of EV development for SIM-Drive, who are looking to get the final production model on sale in 2014.

Not only does the SIM-WIL provide a working test bed for the future production car, but it also showcases SIM-Drive’s technology — their own design of in-wheel motors, as well as techniques to incorporate as many components as possible into the frame of the car itself. These technologies free up as much of the interior space of the car for the passengers.

With this second generation prototype, the SIM-WIL, undergoing testing, SIM-Drive is now turning its attention to the infrastructure that needs to accompany the uptake of the vehicles themselves in order to make electric cars a viable option. In this regard it is joining with companies not traditionally associated with EV development, such as Sekisui House (home construction) and Mitsui Fudosan (real estate) to focus on three key areas of smart homes, smart grids and smart cities. This new phase is scheduled to be complete by the end of March 2013.

Apart from wondering how much the finished car will cost, and whether you will be able to get it outside Japan, the only other question on your mind is probably this: What the heck does “WIL” stand for? Well I will be glad to enlighten you – “With Innovation and Link”.

And with some more “innovation” and “link” “luck”, we will all be driving cars like this a few years from now.

Keio University EV Venture Gets 333 KM Per Charge

Posted by Stephen On Thursday, May 19th, 2011

From the same University that brought you the insane 8-wheeled Eliica electric car comes something a little more practical – the SIM-LEI EV car that gets up to 333 KM per charge, which is quite a bit more than Nissan’s claimed 200KM per charge for the Leaf.

SIM LEI electric car

The car has been built by SIM-Drive, a venture company spun off by Japan’s famous Keio University, and headed by Professor Shimizu. SIM-LEI is a 4-seater with a top speed of 150KM/h and will hit 100KM/h in 4.8 seconds. The latter is well into junior supercar territory – just 0.1 seconds behind the current base model 911.

The most impressive thing is the use of in-wheel electric motors. No commercially-available electric vehicle has yet used this kind of design. Despite this, Shimizu is confident that if production levels reached 100,000 or more per year, then the price per car would be able to be reduced to a level that is below the equivalent gasoline engined car in the same class.

Whether that can be achieved remains to be seen, but it is good to see small private ventures taking on the EV challenge and bringing a dynamism which the large manufacturers can sometimes lack.
