The Toyota Yaris (XP150, facelift 2017) 1.3-liter engine, producing 94 horsepower (and 101 hp on Ethanol – E85), represented an entry-level offering within the refreshed third generation of the Yaris. Introduced in 2018 and continuing through 2020, this variant was primarily aimed at buyers seeking an economical and practical city car. It occupied the lower end of the Yaris lineup, positioned below higher-powered engine options and more generously equipped trim levels. The XP150 series Yaris, a subcompact hatchback, was built on the Toyota B platform, also known as the 1HX0 platform in some markets, and represented a significant update to the second-generation model.
Powertrain & Engine Architecture
The heart of this Yaris variant is the 1NR-FBE engine, a 1.329-liter (81.1 cubic inches) inline-four cylinder gasoline engine. This engine is a naturally aspirated powerplant, meaning it does not utilize a turbocharger or supercharger. It features a multi-port fuel injection system, delivering fuel directly into the intake ports. The engine employs Toyota’s Variable Valve Timing-intelligent (VVT-i) system, which optimizes valve timing for improved fuel efficiency and power delivery across the rev range. The 1NR-FBE boasts a compression ratio of 13:1, contributing to its efficiency. Bore and stroke dimensions are 72.5 mm (2.85 inches) and 80.5 mm (3.17 inches) respectively. The engine is transversely mounted at the front of the vehicle.
While a six-speed manual transmission was standard, this article focuses on the automatic transmission variant. The automatic transmission used in this Yaris is a conventional torque converter automatic, offering smooth shifts and ease of use, particularly in urban driving conditions. Specific gear ratios are not widely published, but the transmission is tuned for fuel economy and relaxed cruising rather than sporty performance. The automatic transmission contributes to a slightly higher curb weight compared to the manual version.
Ethanol (E85) Compatibility
A notable feature of this engine is its flex-fuel capability, allowing it to run on gasoline or E85 ethanol fuel. When running on E85, the engine management system adjusts to compensate for the fuel’s different properties, resulting in a power output increase to 101 horsepower. However, fuel economy is typically reduced when using E85 due to its lower energy density.
Driving Characteristics
The 94 hp 1.3-liter engine paired with the automatic transmission delivers adequate, but not exhilarating, performance. Acceleration is best described as leisurely, with a 0-60 mph time estimated to be around 12-13 seconds. The focus is on providing a comfortable and efficient driving experience rather than sporty handling. The automatic transmission contributes to a smooth and predictable driving experience, making it well-suited for city commuting and highway cruising. The gear ratios are optimized for fuel economy, meaning the engine may feel strained when accelerating quickly or climbing hills. Compared to the more powerful Yaris variants, such as those equipped with larger engines, this 1.3-liter automatic feels noticeably slower. However, it offers a more relaxed and forgiving driving experience, particularly for less experienced drivers.
Equipment & Trim Levels
The 1.3-liter automatic Yaris typically came with a base level of equipment, focusing on essential features. Standard equipment generally included air conditioning, power windows, power door locks, and a basic audio system with Bluetooth connectivity. Safety features such as ABS (Anti-lock Braking System) and multiple airbags were also standard. Interior upholstery was typically cloth, with a simple and functional dashboard layout. Optional extras available for this trim level often included alloy wheels, a touchscreen infotainment system with navigation, and parking sensors. Higher trim levels offered additional features such as automatic climate control, a rearview camera, and upgraded interior materials.
Chassis & Braking
The Yaris XP150 utilizes an independent McPherson strut suspension system at the front, providing a comfortable ride and decent handling. The rear suspension employs a torsion beam setup, which is a cost-effective and space-efficient solution. The front brakes are ventilated discs, offering good stopping power, while the rear brakes are drums. This configuration is typical for vehicles in this weight class. The steering system is an electric power steering rack and pinion, providing light and easy steering feel. The vehicle rides on 15-inch wheels with tire size 185/60 R15.
Market Reception & Comparison
The 1.3-liter automatic Yaris was generally well-received by critics as a practical and economical city car. It was praised for its fuel efficiency, ease of use, and comfortable ride. However, it was also criticized for its lack of power and somewhat basic interior. Compared to other trims in the Yaris lineup, the 1.3-liter automatic offered the lowest price point but also the least amount of performance and features. In terms of fuel economy, it typically achieved around 36-40 mpg combined, depending on driving conditions and fuel type. Reliability was generally considered to be good, consistent with Toyota’s reputation for building durable and dependable vehicles. Competitors in this segment included the Honda Fit, Nissan Versa, and Kia Rio.
