Powertrain & Engine Architecture
At the heart of the Renault Austral 1.3 (140 hp) Mild Hybrid lies the H5Ht engine, a 1.333-liter inline-four cylinder gasoline engine. This engine is part of the Alliance’s (Renault-Nissan-Mitsubishi) modular engine family. It utilizes direct fuel injection and is equipped with a turbocharger and intercooler to enhance power and efficiency. The engine’s output of 140 horsepower at 4,500-5,750 rpm and 260 Nm (191.77 lb.-ft.) of torque between 1,750-3,500 rpm is achieved through careful tuning of the engine management system. The “Mild Hybrid” aspect comes from a 48-volt starter-generator system. This system assists the engine during acceleration, allowing for smoother starts and improved fuel economy. It also enables a start/stop system that operates more seamlessly than traditional systems. The transmission is a 6-speed manual gearbox, chosen to balance cost and driver engagement.
Driving Characteristics
The 1.3-liter Mild Hybrid powertrain delivers a respectable, though not exhilarating, driving experience. Acceleration from 0-100 km/h (0-62 mph) takes approximately 10.7 seconds. The mild hybrid system provides a noticeable boost during initial acceleration, mitigating some of the turbo lag. The 6-speed manual transmission offers a decent shift feel, although it’s not as precise or sporty as some competitors. Compared to higher-output versions of the Austral, this variant feels less powerful, particularly when fully loaded or tackling steep inclines. However, the engine is generally responsive enough for everyday driving situations. The gear ratios are tuned for fuel efficiency, meaning the engine operates at relatively low RPMs during cruising. This contributes to a comfortable ride but can sometimes require downshifting for quicker overtaking maneuvers.
Equipment & Trim Levels
The Renault Austral 1.3 (140 hp) Mild Hybrid typically comes with a generous level of standard equipment. This includes features such as a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, automatic climate control, keyless entry, and a suite of advanced driver-assistance systems (ADAS) like automatic emergency braking, lane departure warning, and traffic sign recognition. Interior upholstery is typically cloth, with options for upgraded materials available on higher trim levels. The dashboard layout is modern and driver-focused, with a digital instrument cluster providing key vehicle information. Optional extras often include a panoramic sunroof, adaptive cruise control, and a premium audio system.
Chassis & Braking
The Austral utilizes a McPherson strut front suspension and a torsion beam rear suspension. This setup provides a good balance between ride comfort and handling. The torsion beam rear suspension is a cost-effective solution that is well-suited for the vehicle’s weight class. The braking system consists of ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) is standard, along with electronic brake-force distribution (EBD). The steering is electric power-assisted, providing a light and responsive feel. Tire sizes vary depending on the trim level, ranging from 215/65 R17 to 205/55 R19.
Market Reception & Comparison
The Renault Austral 1.3 (140 hp) Mild Hybrid has been generally well-received by automotive critics. It’s praised for its fuel efficiency, comfortable ride, and spacious interior. However, some reviewers have noted that the engine can feel underpowered at times, particularly when compared to more powerful competitors. In terms of fuel economy, the Austral 1.3 Mild Hybrid achieves approximately 6.1 l/100 km (38.6 US mpg), which is competitive within its segment. Compared to the higher-output petrol and hybrid versions of the Austral, this variant offers a more affordable entry point but sacrifices some performance. It competes directly with other compact SUVs such as the Peugeot 3008, Volkswagen Tiguan, and Nissan Qashqai.
Legacy
The Renault Austral 1.3 (140 hp) Mild Hybrid represents a significant step towards Renault’s electrification goals. While it’s still relatively early in its lifecycle, the powertrain is expected to prove reliable due to the proven technology used in the engine and mild hybrid system. On the used car market, this variant is likely to appeal to buyers seeking a fuel-efficient and practical SUV at a reasonable price point. The combination of a turbocharged engine, mild hybrid assistance, and a manual transmission offers a good balance of performance, economy, and driver engagement, making it a compelling option in the competitive compact SUV segment.
