Harry’s garage examines a rare 1973 Porsche 911 Carrera RS 2.7 Lightweight (M471), one of about 200 built and just 17 in right-hand drive. Created as a homologation special for racing, the RS became legendary for its performance and engineering. A key feature is the ducktail rear spoiler, added to reduce rear lift at high speeds and improve stability.
The Lightweight version differs significantly from the more comfortable Touring model. Weight savings came from thinner steel panels, fiberglass bumpers, thinner glass, minimal trim, and the removal of sound deadening and amenities like a radio, clock, and glovebox. The result was a homologated weight of about 900 kg, making it far lighter and more competition-focused.
Powered by a 2.7-liter flat-six producing about 210 horsepower, the RS offered improved torque and performance over earlier 911s. The reduced weight and rear-engine traction made it especially effective in motorsport, including rallying.
On the road, the Lightweight feels raw and mechanical, with noticeable engine noise and immediate throttle response. Its sharper, more responsive character compared to the Touring model helps explain why the RS 2.7 Lightweight remains one of the most prized and collectible classic 911s.
