Simon said:A car with less power than its supposed predecessor could hardly be considered an improvement, let alone inheritor to the Gordini performance mantel.
The 17TS/G is basically a detuned 12G sourced motor. The 12G puts out 125bhp @ 6250rpm, the 17TS/G 108bhp @ 6000rpm. The source for both of these figures is Renault documentation.
According to Australian literature of the time the TS/G put out 120bhp vs the 102bhp of the TL. Perhaps the output you are quoting is from the later Phase 2 (new front) model that we did not see here, as it had a different engine. Or perhaps from the US version.
