INTRODUCTION

The Mitsubishi eK X 0.7 Hybrid CVT, introduced in 2019 as part of the third-generation eK series, is a compact Kei car designed for the Japanese market. The “eK” designation stands for “electric K car,” highlighting Mitsubishi’s focus on electrification within this unique vehicle class. The eK X represents the more crossover-oriented variant of the eK, offering slightly increased ground clearance and a more rugged aesthetic compared to the standard eK wagon. This particular variant, powered by a 659cc three-cylinder engine paired with a hybrid system and a continuously variable transmission (CVT), positioned itself as an entry-level option, prioritizing fuel efficiency and affordability over outright performance.

Powertrain & Engine Architecture

At the heart of the eK X 0.7 Hybrid lies the BR06 engine, a 659cc inline-three cylinder gasoline engine. This engine utilizes a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) to optimize efficiency and power delivery. The engine’s small displacement necessitates a relatively high compression ratio of 12:1 to maximize combustion efficiency. The hybrid system employs a small electric motor (SM21) and a lithium-ion battery pack located under the floor. This configuration allows for electric-only operation at low speeds and assists the gasoline engine during acceleration, contributing to the vehicle’s impressive fuel economy. The CVT transmission is tuned for smooth operation and efficiency, prioritizing fuel savings over sporty driving dynamics. The engine utilizes multi-point fuel injection for precise fuel delivery.

Driving Characteristics

The 52 horsepower and 44 lb-ft of torque produced by the eK X 0.7 Hybrid CVT translate to modest, but adequate, performance for urban driving. Acceleration is deliberately unhurried, and the CVT transmission prioritizes maintaining optimal engine speed for fuel efficiency. Compared to higher-trim eK X models equipped with a 660cc turbocharged engine, the 0.7-liter variant feels significantly less powerful, particularly when climbing hills or overtaking. The CVT’s continuously variable ratios eliminate traditional gear shifts, resulting in a smooth, albeit somewhat monotonous, driving experience. The focus is clearly on ease of use and fuel economy rather than engaging driving dynamics. The lightweight nature of the vehicle helps mitigate the lack of power, making it feel nimble in city traffic.

Equipment & Trim Levels

The base-level eK X 0.7 Hybrid CVT typically came equipped with standard features such as air conditioning, power windows, power door locks, and an audio system. Safety features included ABS (Anti-lock Braking System) and airbags. Interior upholstery was typically a basic cloth material. Optional extras included a navigation system, a rearview camera, and alloy wheels. Higher trim levels offered upgrades such as leather upholstery, heated seats, and advanced safety features like automatic emergency braking. The interior design prioritized functionality and space efficiency, maximizing the use of the limited cabin dimensions.

Chassis & Braking

The eK X utilizes a lightweight chassis construction to minimize weight and maximize fuel efficiency. The front suspension consists of independent coil springs, while the rear suspension employs a torsion beam setup. This configuration provides a comfortable ride quality, although it’s not designed for spirited handling. The front brakes are ventilated discs, providing adequate stopping power, while the rear brakes are drums, a cost-saving measure common in this vehicle segment. The electric power steering system offers light and easy steering, making it ideal for maneuvering in tight urban spaces.

Market Reception & Comparison

The Mitsubishi eK X 0.7 Hybrid CVT was well-received in Japan as an affordable and fuel-efficient option within the Kei car segment. Critics praised its practicality, maneuverability, and low running costs. Compared to other eK X variants, the 0.7-liter hybrid model offered the best fuel economy but lacked the performance of the turbocharged versions. It competed directly with other Kei car hybrids from manufacturers like Suzuki and Daihatsu, all vying for the attention of budget-conscious Japanese buyers. The eK X’s relatively spacious interior and comfortable ride quality were also noted as strengths.

Legacy

The Mitsubishi eK X 0.7 Hybrid CVT represents a key example of the engineering principles behind the Japanese Kei car class – prioritizing efficiency, affordability, and practicality. While not available in many international markets, the eK X’s hybrid powertrain and lightweight construction demonstrate Mitsubishi’s commitment to developing fuel-efficient vehicles. On the used car market in Japan, these models are known for their reliability and low maintenance costs, making them a popular choice for first-time car buyers and those seeking an economical mode of transportation. The powertrain, while modest in output, has proven to be durable and relatively trouble-free, contributing to the eK X’s enduring appeal.
