Alfa Romeo 8C 920

Hand-assembled in Modena by Ferrari cross-plane V8 with 4,691 cc — the same F136-YC block as the Maserati GranTurismo, but in the 8C with a transaxle layout (gearbox at the rear axle) for 50:50 weight distribution. 450 hp at 7,000 rpm, limiter at 7,600 rpm, 80% of torque available from 2,500 rpm. The cross-plane V8 sounds deep and throaty — not a shrill Ferrari scream but an Italian-American burble that transitions into a low-frequency roar at full throttle. Evo Magazine named the 8C Spider 'Best Sounding Car' in 2011. Only 829 examples built (500 coupé + 329 Spider; the financial crisis cut the Spider production run). Carbon bodywork on a steel frame, approx. 100 kg lighter than the Maserati donor. The automated 6-speed gearbox shifts in 175 ms in Sport mode — abrupt, but in keeping with the character.

• !! Cam variator: cold-start rattle to valve damage from 50,000 km

  Wet-sump V8 (engine no. <148697, build years 2007–2010) loses oil pressure in the cam phaser galleries on shutdown. ~33% of engines affected. Without repair (check valves + revised phaser units) valve damage is likely.

  Symptoms: Metallic rattling on cold start (5–10 seconds), power loss at low revs, engine warning light.

• !! Coolant hose at the cylinder head bursts from 60,000 km

  Coolant lines between the cylinder banks and behind the right head deteriorate. Access only after removing the intake manifold. Plastic expansion tank also cracks.

  Symptoms: Sudden coolant loss, coolant smell, rising temperature gauge — often without warning.

• !! Oil leak from valve covers and timing cover from 70,000 km

  The V8 valve cover gaskets and cam cover tend to leak oil at higher mileages. Labour is extensive on the 90° V8 due to tight packaging.

  Symptoms: Oil smell after a drive, visible oil drops under the engine, oil film on the cam covers.
