Is the Besturn B70's engine the same as the Mazda 6's?

The engine of the Besturn B70 is not the same as the Mazda 6's. The Besturn B70 2.0L and 1.8T sport models are equipped with the ET3 series high-performance all-aluminum engine and the 4GC series high-performance turbocharged engine, respectively. The Mazda 6 is equipped with 2.0-liter and 2.3-liter inline four-cylinder engines. The introduction of the Besturn B70's engine is as follows: Engine horsepower: With 169 horsepower and a maximum torque of 258 Nm, this engine has a maximum power speed of 5500 rpm and a maximum torque speed ranging from 1300 to 4350 rpm. This engine is equipped with direct injection technology and uses an aluminum alloy cylinder head. Using an aluminum alloy cylinder head can reduce the weight of the engine, thereby improving the car's handling and fuel efficiency. Dual-clutch transmission: This engine is paired with a 7-speed dual-clutch transmission. Using a dual-clutch transmission can improve the car's shifting speed and transmission efficiency. The dual-clutch transmission is a product developed based on the manual transmission, and its structure is similar to that of a manual transmission. One set of clutches in the dual-clutch transmission is used to control the odd-numbered gears, while the other set is used to control the even-numbered gears.
The engine of the Besturn B70 in early models was indeed the same as that of the Mazda 6, based on the models from around 2006 to 2012. For example, the first-generation B70 used Mazda 6's 2.0L or 2.3L naturally aspirated engines, and the driving dynamics felt quite similar, with parts being largely interchangeable during repairs. However, after subsequent upgrades, FAW developed its own new 1.8T or 2.0T engines. The latest B70 models no longer use Mazda 6 engines at all, potentially offering better performance and slightly lower fuel consumption. For used car buyers, the older models share engines, but the newer ones should not be confused. It's best to check the vehicle's production year or engine number to avoid maintenance issues. Overall, whether the engines are the same depends on the specific model year.
