History of the Vauxhall Firenza
Built between 1970-1975, the Vauxhall Firenza was an advancement of the Vauxhall Viva as a coupé rear-wheel drive fastback with 2-doors. It started off as a regular flat-fronted design, but feeling the need to liven up their range Vauxhall decided to re-design the Firenza with Wayne Cherry turning the Vauxhall Firenza HPF into a "Droopsnoot" reminiscent of the Ferrari Daytona whilst the flat-fronted version of the Firenza would carry on being sold known as the Vauxhall Magnum.
The first Firenza was available in 1159 cc overhead-valve form and two versions with overhead camshaft, 1598 cc and 1975 cc variations. The latter utilised the same engine as the previous Viva GT. Six months after debut, in December 1971, the engine capacity was increased to 1256 cc, 1798 cc, and 2279 cc, respectively. All variants were powered by a four-cylinder engine positioned in the front and driving the rear wheels. The suspension consisted of a double-wishbone and coil springs up front and a live rear axle with trailing arms and coils up back. In each engine size, the SL model had the maximum amount of trim.
Independent Tyre Test - The Results
In the world of modern tyres it is commonplace to come across a tyre test. Sadly in the world of classic tyres, the investment never seems to be there to do a proper modern tyre test. However, a German magazine in July 2016 conducted this modern tyre test using classic tyres. This classic tyre test has been translated from German to English. What is remarkable in this tyre test is quite how well the PIRELLI CINTURATO â„¢; CN36 classic tyre performed in the table at the end. The scores in this table are not scored in relation to the other tyres in the test, so when a score of 1 is recorded, then that is a perfect score for a classic tyre or a modern tyre. It is wonderful to see that these classic PIRELLI CINTURATO â„¢; CN36 tyres can give such exemplary results.
