Our Spotlight/Pic-of-the-day comes courtesy of this gorgeous 1964 Alfa Romeo TZ (Tubolare Zagato) Racecar that was developed and built jointly by Zagato and Auto Delta (Alfa Romeo’s Competition Department). The TZ was a purpose-built racecar that utilised a tubular spaceframe chassis clothed in lightweight, all-aluminium body panels that assisted in keeping the overall weight down to a scant 660 kg – That’s nearly half the weight of a Mazda MX-5…
With such feathery weight to propel the TZ, ample power delivery was relied upon a throaty, twin-spark 1.6L inline-4 cyl. engine that chucked out a healthy 160 bhp and enabled the TZ to reach 135 mph. Independent suspension and disc brakes also aided in stability during the varying styles of races it entered throughout its competition-based life.
This exact TZ (pictured) was the 2nd of the non-prototypes to be built. Completed on April 2 1964, just 24 days later it was entered into the Targa Floria where it finished an impressive 3rd overall. Two months later it saw action in the Le Mans 24 Hours where it finished 15th overall – not too shabby for a 4-cyl Alfa Romeo.
From there it was raced throughout the late-’60s until 1967 when its owner, Giancarlo Sala, decided that even more weight could be shed from its shell in the quest for greater performance. How he went about doing this though, remains a questionable (yet characteristic) note on the ‘add lightness’ scale.
After watching bare aluminium Porsches compete (and win) at the Nurburgring, Sala decided to completely strip this very TZ of its paint, both inside and out, exposing it right down to the bare aluminium. He even sanded down the aluminium itself to reduce the thickness in his quest for lessened weight. He probably shaved off a few kilos by doing this. Amazingly, the TZ pictured here remained in its bare-aluminium shell until July 2010 when it was completely restored back to its original Le Mans livery/colours.
In July 2010, the car won 1st-Place honours at the Le Mans Heritage Club Concours. On May 21st of this year it was auctioned off by RM Auctions at Villa d’Este for an astronomical 627,400.000 Euros ($830,110.000)
Nice, sweet-sounding onboard footage captured here just after its complete restoration…
