2006 Toyota Matrix

The 2006 Toyota Matrix is a compact hatchback/wagon known for its reliability, practicality, and fuel efficiency. It was offered with two engine options: a 1.8L 4-cylinder engine (1ZZ-FE) producing around 130 horsepower and 125 lb-ft of torque, and a more powerful 2.4L 4-cylinder engine (2AZ-FE) found in the XRS trim, making approximately 158 horsepower and 162 lb-ft of torque. Transmission options included a 5-speed manual and a 4-speed automatic for the 1.8L engine, and a 5-speed manual or 5-speed automatic for the 2.4L engine. Owners generally appreciate the Matrix’s spacious interior, good gas mileage, and Toyota’s reputation for dependability. Common dislikes often include the somewhat bland styling and, depending on the engine, the lack of thrilling performance.
