At the October 1953 Paris Motor Show Fiat launched a sporting version of the 103, the 1100 TV—standing for "Turismo Veloce", "Fast Touring". The TV was fitted with an improved engine (type "103.006"), which developed at 5,400 rpm rather than the of the regular versions, mainly thanks to a twin-choke Weber carburettor and a higher 7.4:1 (instead of 6.7:1) compression ratio. Later in 1954, compression ratio was raised further to 7.6:1 and power reached . Top speed was . Another notable mechanical difference was the propeller shaft, two-piece instead of one-piece in order to dampen torsional vibrations, intensified by the increased engine output.
