Petrol Engines:
* Early Years (1900s-1960s):
* Four-cylinder: These ranged from small 1.0L engines to larger 1.5L and 1.9L units, typically found in models like the Victor and Viva.
* Six-cylinder: These were less common but were offered in larger cars like the Cresta and Velox.
* 1970s-1990s:
* Family of 1.0L to 1.6L four-cylinder engines: These were developed in collaboration with Isuzu and were used in a wide range of models like the Chevette, Astra, and Cavalier.
* 1.8L and 2.0L four-cylinder engines: These were found in larger models like the Carlton and Senator.
* 2.0L and 2.5L six-cylinder engines: These were available in the top-of-the-line models like the Senator and Carlton.
* Modern Era (2000s-present):
* 1.0L to 1.6L Ecotec engines: These four-cylinder engines were known for their efficiency and were offered in various trims across models like the Corsa, Astra, and Insignia.
* 1.4L and 1.6L Turbocharged engines: These offered more power and performance in models like the Astra GTC and Insignia.
* 2.0L Turbocharged engines: These were primarily used in performance models like the VXR and Insignia VXR.
* New generation engines: These include the 1.2L Turbocharged petrol engine and the 1.5L Turbocharged diesel engine, which emphasize efficiency and reduced emissions.
Diesel Engines:
* Early Years (1980s-1990s):
* 1.5L and 1.7L Isuzu-sourced engines: These were introduced in the 1980s and found in models like the Astra and Cavalier.
* 2.0L and 2.5L engines: Larger diesel options, usually found in the Carlton and Senator.
* Modern Era (2000s-present):
* 1.3L and 1.7L CDTi engines: These were developed in collaboration with Fiat and were known for their fuel economy. They were used in models like the Corsa, Astra, and Insignia.
* 1.6L and 2.0L CDTi engines: These offered more power and torque, found in models like the Astra VXR and Insignia.
* 1.5L and 1.6L Diesel engines: These engines are designed for enhanced efficiency and reduced emissions, found in models like the Corsa and Astra.
Noteworthy Details:
* Vauxhall has also utilized engines from other manufacturers, such as Isuzu, Fiat, and Opel (its sister brand).
* Some models offered "twin-cam" or "double-overhead camshaft" engine configurations for improved performance.
* Vauxhall has been increasingly focusing on downsizing and turbocharging engines to enhance performance and fuel efficiency.
Remember that this is just a general overview. The specific engine options available in each Vauxhall model varied depending on the year, trim level, and market.
