The Vauxhall Zafira C Tourer 2.0 CDTI Automatic, produced between 2014 and 2016, represented a significant evolution of the Zafira line, a popular multi-purpose vehicle (MPV) in the European market. This variant, powered by a 2.0-liter turbocharged diesel engine producing 170 horsepower and paired with a six-speed automatic transmission, occupied a mid-range position within the C Tourer lineup, offering a balance between performance, fuel efficiency, and convenience. It was built on the GM Delta platform, also known internally as the 7XM, and shared components with other Opel/Vauxhall and Chevrolet models of the era.
Powertrain & Engine Architecture
The heart of the Zafira C Tourer 2.0 CDTI Automatic is the B20DTH engine, a four-cylinder, inline diesel engine displacing 1956 cc (119.36 cubic inches). This engine utilizes a common rail direct injection system, delivering fuel at extremely high pressure for optimized combustion. The B20DTH features a variable geometry turbocharger (VGT) and an intercooler, enhancing both power and torque output. The engine’s compression ratio is 16.5:1. The valvetrain employs two overhead camshafts (DOHC) operating four valves per cylinder.
The six-speed automatic transmission, designated as 6T40/6T45 depending on specific build dates and regional variations, is a conventional torque converter automatic. It features electronically controlled shifting and adaptive learning algorithms to optimize gear selection based on driving conditions and driver input. The transmission is known for its relatively smooth operation, though it isn’t considered a performance-oriented unit. Gear ratios are tuned for fuel efficiency and comfortable cruising, rather than rapid acceleration.

Driving Characteristics
The Zafira C Tourer 2.0 CDTI Automatic delivers adequate performance for everyday driving. While not particularly sporty, the 170 horsepower and 400 Nm of torque provide sufficient power for overtaking maneuvers and maintaining comfortable speeds on the highway. The automatic transmission contributes to a relaxed driving experience, particularly in urban environments. However, compared to the six-speed manual version of the same engine, the automatic suffers from a slight performance deficit due to transmission losses and less aggressive shift programming. The automatic transmission prioritizes smooth shifts over outright speed. Acceleration from 0 to 62 mph (0-100 km/h) is typically around 9.4 seconds. The engine is relatively quiet and refined for a diesel, but some engine noise is noticeable under hard acceleration.
Equipment & Trim Levels
The Zafira C Tourer 2.0 CDTI Automatic was typically offered in mid-level trim configurations, such as ‘Design’ or ‘Tech Line’ depending on the specific market. Standard equipment generally included air conditioning, a CD/MP3 stereo system with USB connectivity, electric front windows, electric door mirrors, and remote central locking. Higher trim levels added features like leather upholstery, heated front seats, a touchscreen infotainment system with navigation, rear parking sensors, and automatic climate control. The Zafira C Tourer was renowned for its flexible seating arrangement, offering five or seven seats depending on the configuration. The rear seats could be folded flat into the floor, creating a large and versatile cargo area. Optional extras included panoramic sunroof, adaptive cruise control, and advanced safety features like lane departure warning.
Chassis & Braking
The Zafira C Tourer features an independent suspension system on both the front and rear axles. The front suspension utilizes a McPherson strut design, while the rear employs a multi-link setup with a stabilizer bar. This configuration provides a comfortable ride quality and reasonable handling characteristics. The steering is rack and pinion, offering adequate precision and feedback. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Anti-lock Braking System (ABS) is standard, along with Electronic Brakeforce Distribution (EBD). The vehicle rides on 17-inch alloy wheels, typically fitted with 225/50 R17 tires. The suspension tuning is geared towards comfort rather than sporty handling, prioritizing a smooth ride over sharp cornering.
Market Reception & Comparison
The Zafira C Tourer 2.0 CDTI Automatic received generally positive reviews from automotive critics. It was praised for its spacious interior, flexible seating arrangement, and comfortable ride. The 2.0 CDTI engine was considered a good compromise between performance and fuel economy. However, some critics noted that the automatic transmission could feel sluggish at times, and the interior design was somewhat dated compared to newer competitors. Compared to the 1.6 CDTI engine option, the 2.0 CDTI offered noticeably more power and refinement, but at the cost of slightly higher fuel consumption. The 2.0 CDTI Automatic was also positioned below the more powerful 2.0 BiTurbo diesel variant in the Zafira C Tourer lineup, which offered significantly higher performance but came with a higher price tag. Fuel economy figures averaged around 38.6 US mpg (combined), and CO2 emissions were rated at 161 g/km (Euro 6 compliant).

Legacy
The Zafira C Tourer 2.0 CDTI Automatic, while not without its flaws, remains a practical and reasonably reliable MPV in the used car market. The B20DTH engine is generally considered durable, provided it has been properly maintained. Common issues include diesel particulate filter (DPF) clogging, particularly on vehicles used primarily for short journeys, and potential problems with the turbocharger. The 6T40/6T45 automatic transmission can also experience issues with solenoid failure or valve body wear. However, these issues are not uncommon for automatic transmissions of this era. The Zafira C Tourer’s spacious interior and flexible seating continue to appeal to families, making it a popular choice for those seeking a versatile and affordable MPV. Its relatively good fuel economy and comfortable ride further contribute to its enduring appeal.
