# Mitsubishi eK

The Mitsubishi eK (Japanese: 三菱・イーケイ, Hepburn: Mitsubishi Ē Kei) is a kei car series from Mitsubishi Motors, based on the long-running Minica, and first introduced on October 11, 2001. The "eK" name is an abbreviation for "excellent keijidōsha" (or "excellent minicar") and is meant to be pronounced "ee kay", a pun which sounds like the Japanese いい軽, meaning "good kei [car]".
Since June 8, 2005, Nissan has received 36,000 eK Wagons annually from Mitsubishi, to be sold within the domestic market as the Nissan Otti. The Otti was replaced by the Nissan Dayz on June 6, 2013, although the Otti was still sold alongside the Dayz until being discontinued on June 28, 2013.
In April 2016, Mitsubishi admitted that its employees had falsified fuel efficiency data for the eK Wagon, eK Space, Nissan Dayz and Nissan Dayz Roox. The resultant scandal culminated in Nissan acquiring a controlling interest in Mitsubishi the following month.

## eK
### First generation (2001)

In its first generation, it was available either as an eK Wagon (introduced on October 11, 2001), eK Sport (introduced on September 2, 2002), eK Classy (introduced on May 26, 2003) or eK Active (introduced on May 25, 2004). On December 20, 2005, the eK Classy was discontinued. The eK Wagon was released in a simplified lineup, in only a single model (M) with an available package (M+X) including alloy wheels and some other cosmetics. It was only available with the 3G83, naturally aspirated three-cylinder engine with 50 PS (37 kW); other models later added the option of a turbocharged version with 64 PS (47 kW). The standard transmission was a three-speed automatic with a column shift, later a four-speed version was added, while some models could also be fitted with a five-speed manual with a floor-mounted shifter. Most models could be had with either front- or four-wheel drive.
Immediately upon its release it was the recipient of the Good Design Award by the Japanese Ministry of Economy, Trade and Industry in 2001. While the initial sales target was 10,000 units per month, it sold 13,000 in its first four days, and 20,000 by the end of October 2001. It was Mitsubishi's highest volume model in the Japanese domestic market, and total sales to 2005 are approximately 480,000. In Japan, it was sold at a specific retail chain called Car Plaza.
The crossover eK Active model was introduced in May 2004, shortly before the model was facelifted. Fitted with 14-inch wheels, ground clearance was increased by 10 mm (0.4 in) while the front seats sat 45 mm (1.8 in) higher. The addition of body cladding in dark grey imparted an off-road look to the model; the front clip was also different, featuring the new corporate face conceived by Olivier Boulay. The eK Active was available with either engine (the V model being naturally aspirated, VT the turbocharged model) but only with the four-speed automatic; both models also had optional four-wheel drive.
The eK Wagon G model, with more equipment and the four-speed automatic, was added in May 2003, originally only as the "M20G Thanks Edition", celebrating 200,000 sales. In August 2003 the G became a standard model, while the X-package was discontinued. A facelifted eK Wagon was introduced on December 20, 2004; the eK Active was not changed apart from receiving redesigned hubcaps.
