2018-2023 MG RX5 1.5T (169 Hp) TST

The MG RX5 1.5T (169 Hp) TST, produced from 2018 to 2023, represents MG Motor’s entry into the competitive compact SUV segment. Introduced as a key model in MG’s revitalization strategy, particularly in markets like China and parts of Europe, the RX5 aimed to offer a value-oriented alternative to established brands. This specific variant, powered by a 1.5-liter turbocharged engine paired with a 7-speed automatic transmission (TST – likely denoting a specific transmission calibration), occupied a mid-range position within the RX5 lineup, balancing affordability with a reasonable level of performance and features. It was designed to appeal to buyers seeking a practical, spacious, and relatively modern SUV without the premium price tag of European or Japanese competitors.

Technical Specifications

Positioning and Market Role

The MG RX5, launched as a cornerstone of SAIC Motor’s (MG’s parent company) international expansion, was primarily targeted at emerging markets and price-sensitive consumers. In China, it quickly gained traction as a popular SUV offering a compelling combination of space, features, and affordability. European sales, while smaller, focused on offering a budget-friendly alternative to established European and Asian brands. The 1.5T TST variant was positioned as a sweet spot in the RX5 range. Lower trims typically featured a naturally aspirated 1.5-liter engine with less power, while higher trims offered a more powerful 2.0-liter turbocharged engine. The 1.5T provided a noticeable performance upgrade over the base engine without the added cost of the 2.0T, making it attractive to buyers who wanted a reasonably spirited driving experience.

Engine and Transmission Details

The heart of the RX5 1.5T is the 15E4E, a 1.5-liter inline-four cylinder gasoline engine equipped with a turbocharger and direct fuel injection. This engine produces 169 horsepower at 5600 rpm and 250 Nm (184 lb-ft) of torque between 1700 and 4400 rpm. The turbocharger helps to mitigate turbo lag and provide a broad torque curve, making the engine feel responsive in everyday driving situations. The engine’s direct injection system improves fuel efficiency and reduces emissions. Paired with this engine is a 7-speed automatic transmission, branded as “TST” by MG. While specific details about the TST transmission’s internal workings are limited, it’s understood to be a conventional automatic with a torque converter, optimized for smooth shifts and fuel economy. The transmission contributes to the RX5’s relatively relaxed cruising demeanor.

Comparison with Other RX5 Variants

The RX5 lineup offered several engine and transmission options. The base model typically featured a naturally aspirated 1.5-liter engine producing around 118 horsepower. This engine prioritized fuel economy over performance and was geared towards buyers who primarily used the vehicle for city driving. The 2.0-liter turbocharged engine, found in higher trims, delivered significantly more power – around 220 horsepower – and offered a more engaging driving experience. However, it came at a higher price point and with slightly increased fuel consumption. Compared to the 1.5T, the base engine felt underpowered, especially when fully loaded or tackling inclines. The 2.0T, while more powerful, was often considered less practical for everyday use due to its higher running costs. The 1.5T TST, therefore, struck a balance, offering a good compromise between performance, fuel efficiency, and affordability. In terms of maintenance, the 1.5T engine is generally considered reliable, but like all turbocharged engines, it requires regular oil changes and attention to the turbocharger system. The TST transmission, while generally dependable, may require servicing at recommended intervals to ensure smooth operation.

Suspension and Handling

The MG RX5 1.5T utilizes an independent McPherson strut suspension at the front and an independent multi-link suspension at the rear. This suspension setup aims to provide a comfortable ride quality while maintaining reasonable handling characteristics. The steering is electrically assisted, offering light and easy steering feel, which is well-suited for urban driving. While not a particularly sporty SUV, the RX5 1.5T provides a stable and predictable driving experience. The ABS (Anti-lock Braking System) enhances safety by preventing wheel lockup during hard braking.

Interior and Features

The interior of the RX5 1.5T is designed to be spacious and practical. It offers seating for five passengers and a generous amount of cargo space, with 595 liters (21.01 cu. ft.) with the rear seats up and 1639 liters (57.88 cu. ft.) with the rear seats folded down. Features typically included in the 1.5T TST variant include air conditioning, a touchscreen infotainment system, Bluetooth connectivity, and basic safety features. Higher trim levels added features such as leather upholstery, a sunroof, and advanced driver-assistance systems.

Legacy

The MG RX5 1.5T played a significant role in re-establishing the MG brand in international markets. It demonstrated MG’s ability to produce a competitive SUV at an attractive price point. While the RX5 has since been updated and replaced by newer models, the 1.5T variant remains a popular choice in the used car market, offering a compelling value proposition for buyers seeking a practical and affordable compact SUV.
