Introduction
The Mitsubishi eK X 0.7T Hybrid CVT, introduced in 2019 as part of the third-generation eK series, is a compact and efficient vehicle tailored to the unique demands of the Japanese Kei car class. The “Kei” classification imposes strict limitations on vehicle dimensions and engine displacement, resulting in cars designed for maneuverability in crowded urban environments and favorable tax benefits. The eK X represents Mitsubishi’s attempt to modernize the Kei car experience, offering a blend of practicality, fuel economy, and a slightly more crossover-inspired aesthetic. This 0.7T Hybrid variant serves as an entry point into the eK X range, focusing on maximizing fuel efficiency and minimizing cost.
Powertrain & Engine Architecture
At the heart of the eK X 0.7T Hybrid is the BR06 engine, a 659cc inline three-cylinder unit featuring a turbocharger and intercooler. This engine utilizes direct fuel injection and a double overhead camshaft (DOHC) valvetrain with variable valve timing (VVT) to optimize performance and efficiency. The turbocharger helps to compensate for the small displacement, providing a reasonable level of power for its size. The engine is paired with a 2.7 horsepower electric motor, powered by a lithium-ion battery located under the floor. This configuration allows for electric-only driving at low speeds and assists the gasoline engine during acceleration, contributing to improved fuel economy. The powertrain utilizes a continuously variable transmission (CVT), chosen for its smooth operation and efficiency. The CVT is tuned for economy rather than sporty performance, prioritizing seamless acceleration and minimizing engine strain.
Driving Characteristics
The 0.7T Hybrid CVT delivers modest performance, with 64 horsepower and 74 lb-ft of torque. Acceleration is adequate for city driving, but highway merging and overtaking require careful planning. The CVT contributes to a smooth, linear power delivery, but lacks the responsiveness of a traditional automatic or manual transmission. The electric motor provides a small boost during initial acceleration, helping to mitigate the engine’s inherent lag. The vehicle’s lightweight construction (around 1920-1940 lbs) helps to offset the limited power output. The focus is clearly on fuel efficiency; the eK X 0.7T Hybrid achieves impressive fuel economy figures, making it an ideal choice for daily commutes.
Equipment & Trim Levels
The eK X 0.7T Hybrid CVT typically comes standard with features such as air conditioning, power windows, power door locks, and a basic audio system. Safety features include ABS (Anti-lock Braking System) and airbags. Higher trim levels offer additional features like alloy wheels, a touchscreen infotainment system, and advanced safety technologies such as lane departure warning and automatic emergency braking. Interior upholstery is typically cloth, with a functional and durable design. The dashboard layout is straightforward and user-friendly, prioritizing ease of use over luxury.
Chassis & Braking
The eK X utilizes a front-engine, front-wheel-drive layout. The front suspension consists of independent coil springs, while the rear suspension employs a torsion beam setup. This configuration provides a comfortable ride quality, suitable for navigating urban roads. The front brakes are ventilated discs, offering adequate stopping power, while the rear brakes are drums, a cost-saving measure common in the Kei car segment. The steering is rack and pinion with electric power assistance, providing light and precise steering feel.
Market Reception & Comparison
The Mitsubishi eK X 0.7T Hybrid CVT has been well-received in Japan, where it competes with other Kei car models such as the Suzuki Wagon R and the Daihatsu Move. Critics have praised its fuel efficiency, spacious interior (for its size), and practical features. Compared to higher-output versions of the eK X, the 0.7T Hybrid offers lower performance but significantly better fuel economy. It’s targeted towards buyers who prioritize economy and practicality over driving excitement. The 0.7T Hybrid is generally considered more reliable than some of the more complex, higher-performance variants, due to its simpler engine and drivetrain.
Legacy
The Mitsubishi eK X 0.7T Hybrid CVT represents a modern take on the Kei car formula, offering a compelling combination of fuel efficiency, practicality, and affordability. While not widely available outside of Japan, it has established itself as a popular choice for urban commuters and small families. The powertrain, while modest in terms of power, has proven to be relatively reliable, and well-maintained examples are likely to remain viable transportation options for years to come. The eK X continues to be a significant model for Mitsubishi, demonstrating the company’s commitment to the Kei car segment and its ability to innovate within the constraints of this unique vehicle class.
