The Scion xB II 2.4i Automatic, produced from 2007 to 2011, represented a significant evolution of Scion’s distinctive boxy urban crossover. This variant occupied the mid-range position within the xB II lineup, offering a balance between affordability and performance compared to the base model (if offered) and potential limited edition trims. It was built on the Toyota MC platform, shared with other compact vehicles of the era, and aimed at a demographic seeking a unique, practical, and customizable vehicle. The xB II, in general, was a deliberate departure from conventional automotive design, prioritizing interior space and a distinctive aesthetic over traditional notions of sporty handling or luxury.
Powertrain & Engine Architecture
The heart of the xB II 2.4i Automatic is the 2AZ-FE 2.4-liter inline-four cylinder engine. This engine is a member of Toyota’s AZ series, known for its reliability and relatively simple design. The 2AZ-FE features a cast iron block and an aluminum cylinder head, contributing to a reasonable balance between durability and weight. It utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports just before the intake valves. This system, while not as advanced as direct injection, proved to be dependable and efficient for its time. The engine is equipped with a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, enhancing volumetric efficiency and contributing to the engine’s 158 horsepower output at 6000 rpm and 162 Nm (119.49 lb-ft) of torque at 4000 rpm. The compression ratio is set at 9.8:1.
Paired with the 2AZ-FE engine is a 5-speed automatic transmission. This transmission, a common unit used in various Toyota and Scion models of the period, is designed for smooth and reliable operation. It features electronically controlled shifting, adapting to driving conditions and driver input. While not a particularly sporty transmission, it prioritizes comfort and ease of use, aligning with the xB’s overall character. The transmission is front-wheel drive, as with all xB II models.

- Fuel Injection: Multi-port
- Engine Oil Capacity: 3.8 liters (4.02 US qt / 3.34 UK qt)
Driving Characteristics
The xB II 2.4i Automatic delivers adequate, though not exhilarating, performance. The 158 hp engine provides sufficient power for everyday driving situations, including city commuting and highway cruising. Acceleration from a standstill is reasonable, but the automatic transmission can sometimes feel hesitant, particularly during quick overtaking maneuvers. The 5-speed automatic transmission’s gear ratios are tuned for fuel efficiency and smooth operation rather than aggressive acceleration. Compared to a manual transmission equipped xB II, the automatic version sacrifices some responsiveness. The automatic transmission does offer a more relaxed driving experience, particularly in stop-and-go traffic. The xB II’s relatively high center of gravity and soft suspension tuning contribute to a comfortable ride, but also limit its cornering ability. It’s designed for practicality and comfort, not sporty handling.
Equipment & Trim Levels
The xB II 2.4i Automatic typically came standard with a respectable array of features for its price point. Standard equipment generally included air conditioning, power windows and locks, a CD player with MP3 compatibility, and an anti-theft system. Interior upholstery was typically a durable cloth material, available in various color combinations. The dashboard featured a straightforward design with easy-to-read gauges. Optional extras included a premium audio system with upgraded speakers, a sunroof, and alloy wheels. Some models were also offered with a navigation system, though this was less common. The xB II was also known for its customization potential, with a wide range of aftermarket accessories available, allowing owners to personalize their vehicles to their individual tastes.
Chassis & Braking
The xB II utilizes a MacPherson strut front suspension and a torsion beam rear suspension. This suspension setup provides a comfortable ride, absorbing bumps and irregularities in the road surface effectively. The torsion beam rear suspension is a cost-effective and space-saving design, suitable for the xB’s intended purpose as an urban crossover. Braking duties are handled by ventilated discs on the front wheels and solid discs on the rear wheels. The braking system is assisted by an Anti-lock Braking System (ABS), enhancing safety and control during emergency braking situations. The xB II’s relatively lightweight construction contributes to its braking performance. Stabilizer bars were included, though their thickness was modest, reflecting the vehicle’s focus on comfort rather than sporty handling.
Market Reception & Comparison
The Scion xB II 2.4i Automatic received generally positive reviews from automotive critics. It was praised for its unique styling, spacious interior, and affordability. Critics noted that the automatic transmission could be somewhat sluggish, and the handling was not particularly engaging. However, the xB II’s overall practicality and distinctive character resonated with its target audience. Compared to other vehicles in its class, such as the Honda Fit or Nissan Versa, the xB II offered a more spacious interior and a more distinctive design. Fuel economy was respectable, averaging around 22 mpg city and 28 mpg highway. Reliability was generally good, consistent with Toyota’s reputation for building durable vehicles. The xB II’s maintenance costs were also relatively low, making it an attractive option for budget-conscious buyers.
