*All pre-Lotus cars with manual transmission were fitted with a Limited Slip Differential; this feature was an extra-cost option on manual transmission Handling by Lotus models and is identified on both variants by the option code “G80” on the specification plate, riveted to the engine compartment firewall directly behind the engine. None of the automatic transmission Piazzas were fitted with LSDs.
