[DelReed]

Besturn B70 is equipped with Aisin's F21 six-speed automatic manual transmission, which further enhances comfort and handling, outperforming Mazda's five-speed automatic manual transmission. The vehicle exhibits excellent gearshift smoothness and overall drivability. The Besturn B70 is a product of FAW, classified as a mid-size sedan with the following dimensions: length 4810mm, width 1840mm, height 1455mm, wheelbase 2800mm, fuel tank capacity 50L, and curb weight 1440kg. The new-generation Besturn B70 is powered by a 1.5T turbocharged engine delivering maximum power of 124kW and peak torque of 258Nm. This engine features ultra-high-pressure direct injection with a thermal efficiency of 39%. It is paired with a 6-speed manual transmission. In terms of chassis design, the Besturn B70 utilizes the same large-area high-strength steel as the Mazda6, which not only improves chassis rigidity but also reduces overall vehicle weight. The suspension configuration varies by trim level: lower trims feature front MacPherson strut independent suspension with rear torsion beam non-independent suspension, while higher trims are equipped with front multi-link independent suspension. The suspension tuning is soft, delivering exceptional ride comfort.
