1974 Porsche 911 Carrera RS 3.0

In 1974 the roadworthy motorsport 911 series continued its run. With a bore/stroke ratio of 95 x 70.4 mm the car had a displacement of 2,993. With its systematic lightweight construction the RS 3.0 only weighed in at 900 kg.

This low weight was achieved by using thin-gauge sheet parts and an emaciated equipment level. The braking system on the 911 provided steadfast deceleration even under the highest stresses. — Porsche
