TriumphTR7 Sprint

The Triumph TR7 Sprint version of the Triumph TR7 sports car was produced in 1977 by the Triumph Motor Company, then part of British Leyland. However, it was produced in only very limited numbers: Probably a maximum of 61 in total were manufactured. It used the 127 bhp, 16-valve, 2-litre version of the Triumph slant-four engine from the Triumph Dolomite Sprint, a highly tuned version of which, "rated at 225 bhp at 8000 rpm" by 1977, was used in the Group 4 TR7 cars of the BL works rally team, from 1976 until 1978. This was instead of the TR7 base model's 105 bhp, 8-valve, 2-litre version of the same basic slant-4 engine. The 16-valve version was originally specified in the Dolomite Sprint at 135 bhp, and "Spencer King relates how he went away on holiday and came back to find an engine running on the bed giving 150 bhp at the first build."
