Mitsubishi eK Series: A Comprehensive Guide

The Mitsubishi eK series (eK being short for "Excellent Keijidosha," meaning excellent minicar) is a line of kei cars manufactured by Mitsubishi Motors since 2001. Developed to offer practical, economical, and compact transportation, the eK series caters primarily to the Japanese domestic market (JDM) but has also seen exports to other regions. The series encompasses several models, including the eK Wagon, eK Custom, eK Space, and eK X, each offering slightly different styling and features while remaining within the kei car regulations.

Generations

First Generation (2001-2006)

  • Years: 2001-2006
  • Key Changes: The original eK Wagon was introduced as a simple, boxy kei car focused on practicality and affordability. It featured a 660cc engine (naturally aspirated and turbocharged options) and available in both front-wheel drive (FWD) and all-wheel drive (AWD).
  • Models: eK Wagon

Second Generation (2006-2013)

  • Years: 2006-2013
  • Key Changes: A redesigned eK Wagon was launched, featuring a more modern exterior and interior. Engine options remained similar, but improvements were made to fuel economy and ride comfort. A slightly sportier eK Sport variant was also offered.
  • Models: eK Wagon, eK Sport

Third Generation (2013-2019) - Nissan Dayz Partnership

  • Years: 2013-2019
  • Key Changes: This generation marked a significant shift as Mitsubishi partnered with Nissan to jointly develop and produce the eK Wagon (sold as the Nissan Dayz) and the eK Custom (sold as the Nissan Dayz Highway Star). This collaboration resulted in improved design, technology, and fuel efficiency. The eK Space, a taller, more spacious variant, was also introduced.
  • Models: eK Wagon, eK Custom, eK Space

Fourth Generation (2019-Present) - eK X Introduction

  • Years: 2019-Present
  • Key Changes: The current generation maintains the Nissan partnership, with the eK Wagon and eK X (pronounced "cross") sharing platforms with the Nissan Dayz and Nissan Roox respectively. The eK X features a more rugged, crossover-inspired design, while the eK Wagon maintains a focus on practicality. A new turbocharged engine with mild hybrid technology was introduced for enhanced fuel economy and performance. Advanced safety features, such as adaptive cruise control and lane departure warning, became available.
  • Models: eK Wagon, eK X, eK Space (Nissan Roox)

Reliability & Common Issues

The Mitsubishi eK series, generally, has a reputation for decent reliability, especially when properly maintained. However, like any vehicle, certain common issues can arise:

  • Engine Issues (660cc): The small 660cc engines, especially turbocharged versions, can be susceptible to oil leaks and turbocharger failure if oil changes are neglected. Regular servicing is crucial. Carbon buildup can also be an issue, impacting performance and fuel economy. Consider using premium fuel occasionally and ensuring proper PCV valve function.
  • CVT Transmission: The Continuously Variable Transmission (CVT) used in many eK models is generally reliable, but proper fluid changes at recommended intervals are critical. Neglecting CVT fluid changes can lead to slipping, jerky acceleration, and ultimately, transmission failure. Pay close attention to any unusual noises or vibrations coming from the transmission.
  • Suspension Components: Like most kei cars, the suspension components are lightweight and can wear out prematurely, especially on rough roads. Listen for clunking noises and inspect ball joints, bushings, and shock absorbers regularly.
  • Rust (Older Models): Older eK Wagons (first and second generation) can be prone to rust, particularly in areas with harsh winters or coastal environments. Carefully inspect the undercarriage, wheel wells, and around door seams for rust before purchasing.
  • Sensor Issues (Later Models): Newer models with advanced safety systems can sometimes experience sensor malfunctions, leading to warnings and potential system inoperability. Ensure all safety systems are functioning correctly before purchasing. Diagnostic scans can help identify potential issues.
  • Electrical Issues: Check all electrical components like power windows, door locks and lights. Due to the age of some models, wiring can become brittle and cause issues.

Driving Experience

Pros:

  • Fuel Efficiency: The eK series is renowned for its excellent fuel economy, making it an ideal choice for city driving and commuting.
  • Maneuverability: The small size and tight turning radius make the eK series incredibly easy to maneuver in congested urban environments.
  • Parking: Finding parking spaces is significantly easier due to the compact dimensions.
  • Affordability: Both purchase price and running costs are generally lower compared to larger vehicles.
  • Cabin Space (eK Space/Roox): The eK Space/Nissan Roox offers surprisingly good cabin space for a kei car, thanks to its tall body design.

Cons:

  • Performance: The 660cc engine can feel underpowered, especially when carrying passengers or driving uphill. The turbocharged versions offer better performance but may still struggle on steep inclines.
  • Ride Comfort: The ride quality can be somewhat bumpy, particularly on older models. Newer models with updated suspension systems offer improved comfort.
  • Safety (Older Models): Older eK models may lack modern safety features like airbags, ABS, and stability control.
  • Limited Storage Space: Cargo space is limited, especially in the standard eK Wagon models. The eK Space offers more cargo capacity.
  • Wind Noise: Due to the small size and emphasis on weight reduction, wind noise can be noticeable at higher speeds.

Buying Advice

  • Years to Look For: 2019 and newer models (fourth generation) offer the most advanced features, including improved safety, fuel economy, and technology. The turbocharged engine with mild hybrid technology in these models is a significant upgrade.
  • Years to Avoid (or be cautious of): First and second generation models (2001-2013) may have higher mileage, increased risk of rust, and lack modern safety features. If considering these models, a thorough inspection is essential.
  • Consider Your Needs: If you need maximum space, the eK Space/Nissan Roox is the best choice. If you prefer a more rugged look, the eK X is a good option. For basic, affordable transportation, the eK Wagon is a solid choice.
  • Check the Service History: A well-maintained eK series will be more reliable in the long run. Look for evidence of regular oil changes, CVT fluid changes, and other routine maintenance.
  • Test Drive Thoroughly: Pay attention to the engine performance, transmission smoothness, suspension comfort, and brake feel during the test drive. Listen for any unusual noises or vibrations.
  • Pre-Purchase Inspection: Consider having a qualified mechanic perform a pre-purchase inspection to identify any potential issues before you buy.
  • Insurance: Kei cars often benefit from reduced insurance costs, but this is area specific. Check your local regulations and insurance company.
  • Understand Kei Car Regulations: Be aware of the kei car size and engine limitations in your region. These regulations may affect registration and taxation.
