The Carrera 4 model also launched with a Cabriolet version in 1989 (for 1990 model year).
The new 911 generation is introduced in Autumn 1988, but the convertible was not launched until the model year 1990. Alterations to the body include the bumpers and sill tread plates, and the 911 continues to be equipped with an automatically retractable rear spoiler and a cowled underbody. The braking system is fitted with ABS. The 911 (Type 964) also features power-assisted steering for the first time.
Like the Coupe, the Cabriolet got the new all-wheel drive system. The added weight needed meant that both the Coupe and Cab needed ABS brakes and power steering (a first for a 911). Both cars also had the same bigger 3.6 liter engine. Performance for the 964 Carrera 4 Cabriolet was slightly slower than the coupe. In addition to the Coupe and Cabriolet versions, the 964 Carrera 4 had a Targa body style. Power came from the same dry sumped naturally aspirated 3.6 liter flat 6 (other parts were essentially the same as the coupe and cab). Only 1,329 of the C4 Targas were sold and it was the last with traditional removable Targa roof (till 2011).
