275 GTB Competizione Speciale

Technical Specifications

The 275 GTB/LM's are powered by the type 213 engine, tuned to the same specifications as the 275 LM 290 - 302 bhp

The chassis is a special round tube, lightweight unit, built specially for the LMS's. The bodywork on these cars is much more streamlined than the standard 275's, with larger and taller rear fenders which look like the 250 GTO's. They have a beautiful tailored nose with a lovely hood blister. No bumpers, although there are air induction holes on the front below the driving lights.

These four or five very special cars have superlightweight alloy bodywork and are built to 7/8 scale of the standard 275's.
