The 2009 Scion xB runs on Toyota's 2.4-liter inline-4, the 2AZ-FE, delivering about 158 horsepower and around 162 lb-ft of torque.
Engine fundamentals
The engine powering the 2009 xB is the 2AZ-FE, a 2.4-liter inline-4 that was widely used across Toyota and Scion models. It features dual overhead cams, 16 valves, and variable valve timing with intelligence (VVT-i) to improve both low-end response and highway efficiency. In the xB, this setup is tuned for predictable acceleration and solid mid-range torque, aligning with the vehicle’s practical, cargo-friendly design.
Core features of the 2AZ-FE
Key specifications for the engine in the 2009 xB include:
- Engine: 2.4-liter inline-4 (2AZ-FE)
- Valvetrain: DOHC, 16 valves, VVT-i
- Displacement: 2,362 cc
- Power: 158 hp (118 kW) at around 6,000 rpm
- Torque: 162 lb-ft (220 Nm) at roughly 4,400 rpm
- Fuel system: Sequential multi-point fuel injection
- Compression ratio: about 10.0:1
These specs reflect a mainstream powerplant designed for reliability, with sufficient output for daily driving and a comfortable highway pace.
Transmission options and driving characteristics
In the 2009 xB, the engine was paired with two possible transmissions, depending on trim and market. The setup favors versatility and ease of use over sporty performance.
Transmission choices explained
- 5-speed manual transmission (available on certain trims)
- 4-speed automatic transmission (standard on most models)
Regardless of the transmission, the xB remains a practical, roomy hatchback with a modest but adequate power delivery and a focus on comfort and utility rather than outright speed. The manual offers a bit more driver involvement, while the automatic is typically preferred for daily commuting.
Fuel economy and performance context
Fuel economy figures for the 2009 xB vary slightly by transmission and driving conditions, but typical EPA ratings place the vehicle in the low- to mid-20s mpg in city driving and high-20s to around 30 mpg on the highway. The 2AZ-FE’s torque curve helps with brisk-ish city merging and highway cruising without demanding premium fuel.
In context, the 2009 Scion xB prioritizes interior space, cargo flexibility, and reliability. The engine delivers steady, usable power rather than high-rev performance, fitting the car’s practical, go-everywhere mission.
Summary
The 2009 Scion xB uses Toyota's 2AZ-FE 2.4-liter inline-4, producing about 158 horsepower and around 162 lb-ft of torque. Paired with either a 5-speed manual or a 4-speed automatic, it emphasizes strength in mid-range torque, durability, and everyday practicality over sheer acceleration.
