INTRODUCTION
The Mitsubishi eK X 0.7 T (64 Hp) 4WD Hybrid CVT, launched in 2019, is a significant model within the second generation of the eK X kei car series. Built on the HA3W platform, it represents Mitsubishi’s commitment to providing practical and efficient transportation solutions tailored to the specific needs of the Japanese market. The “0.7 T” designation refers to the engine displacement and the inclusion of a turbocharger, while “4WD Hybrid CVT” details the drivetrain and transmission configuration. This variant aims to bridge the gap between the base models and the more premium trims, offering a compelling combination of fuel economy, maneuverability, and all-weather capability.
Powertrain & Engine Architecture
At the heart of the eK X 0.7 T lies the BR06 engine, a 659cc inline-three cylinder gasoline engine equipped with a turbocharger and intercooler. This engine utilizes a DOHC valvetrain with Variable Valve Timing (VVT) to optimize performance and efficiency. The engine produces 64 horsepower at 5600 rpm and 100 Nm (73.76 lb-ft) of torque between 2400 and 4000 rpm. The turbocharger significantly boosts low-end torque, addressing a common limitation of small-displacement engines. The engine is paired with Mitsubishi’s ‘e-Assist’ mild hybrid system, featuring a small electric motor (SM21) producing 2.7 hp and 40 Nm of torque. This system provides electric assistance during acceleration and enables regenerative braking, contributing to improved fuel economy. The powertrain is coupled with a continuously variable transmission (CVT), chosen for its smooth operation and efficiency. The CVT is tuned to prioritize fuel economy, with gear ratios optimized for everyday driving conditions.
Driving Characteristics
The eK X 0.7 T 4WD Hybrid CVT delivers a surprisingly capable driving experience for its size and engine displacement. The turbocharger mitigates the typical sluggishness associated with small engines, providing adequate acceleration for urban and highway driving. While not a performance-oriented vehicle, the combination of the turbocharger and electric motor assistance provides a responsive feel. The CVT, while efficient, can sometimes feel less engaging than a traditional automatic transmission, exhibiting the characteristic “rubber band” effect. The all-wheel-drive system enhances traction and stability, particularly in inclement weather conditions, making it a practical choice for regions with snow or rain. The suspension is tuned for comfort, absorbing bumps and providing a relatively smooth ride. However, the compact size and lightweight construction mean that body roll is noticeable during cornering.
Equipment & Trim Levels
The eK X 0.7 T 4WD Hybrid CVT typically includes standard features such as air conditioning, power windows, power door locks, and a basic audio system. Safety features include ABS, airbags, and stability control. Higher trim levels add features like a touchscreen infotainment system with navigation, automatic climate control, keyless entry, and alloy wheels. Interior upholstery is typically cloth, with options for upgraded materials on higher trims. The dashboard layout is functional and straightforward, prioritizing ease of use. Optional extras often include parking sensors, a rearview camera, and advanced driver-assistance systems (ADAS) such as lane departure warning and automatic emergency braking.
Chassis & Braking
The eK X utilizes a lightweight chassis construction to maximize fuel efficiency. The front suspension consists of independent coil springs, while the rear suspension employs an independent multi-link setup. This configuration provides a good balance between ride comfort and handling. The braking system features ventilated discs on the front wheels and drum brakes on the rear. While adequate for the vehicle’s weight and performance, the rear drum brakes are a cost-saving measure typical of kei cars. Electric power steering provides light and precise steering feel, making it easy to maneuver in tight spaces.
Market Reception & Comparison
The Mitsubishi eK X 0.7 T 4WD Hybrid CVT has been well-received in the Japanese market, praised for its fuel efficiency, practicality, and affordability. Critics have noted the improved performance compared to naturally aspirated kei car engines, thanks to the turbocharger. Compared to other trims in the eK X lineup, the 0.7 T offers a noticeable performance upgrade over the base models while remaining more affordable than the higher-specification variants. Compared to competitors like the Suzuki Hustler and Daihatsu Thor, the eK X offers a competitive combination of features and fuel economy. The hybrid system contributes to excellent fuel economy figures, making it an attractive option for cost-conscious buyers.
Legacy
The Mitsubishi eK X 0.7 T 4WD Hybrid CVT represents a significant step forward in the kei car segment, demonstrating that small-displacement engines can deliver respectable performance and efficiency with the aid of turbocharging and hybrid technology. While its long-term reliability is still being assessed, Mitsubishi has a generally good reputation for building durable vehicles. On the used car market, the eK X 0.7 T is expected to hold its value reasonably well, particularly among buyers seeking a practical and fuel-efficient city car. Its compact size, all-wheel-drive capability, and hybrid powertrain make it a versatile and appealing option for Japanese drivers.
