Alfa Romeo 4C in action at the Goodwood Festival of Speed (video)

The Alfa Romeo 4C made its dynamic debut (pictured) at the 2013 Goodwood Festival of Speed The long awaited Alfa Romeo 4C finally made its debut in production spec at the Geneva Motor Show in March, and at the weekend the 4C made its dynamic debut at the Goodwood Festival of Speed. To make sure the 4C made as big an impact as possible at Goodwood, we’d expected Alfa to run up the hillclimb in the launch edition 4C, which gets plenty of extra goodies including a carbon fibre body kit and spoiler, but this 4C looked to be a standard model. But even though we’d like to have seen the launch edition with its extra carbon fibre goodies, the standard car gets exactly the same 1750cc 4-cylinder petrol engine with enough get up and go, 236bhp, to move the lightweight 4C (under 900kg) to 62mph in just 4.5 seconds.

Concept Car of the Week: DeTomaso Zonda (1971)

Not satisfied in producing one of the most astonishing sports cars of the ‘60s with the Mangusta, Italian carmaker DeTomaso asserted its ambitions in 1970 by presenting an even more striking sports car, the Pantera, alongside the luxurious Deauville four-door sedan, both powered by the same Ford V8 engine. Those new gorgeous models were the work of Dutch-born Tom Tjaarda, then head of design at Ghia. Despite those amazing cars, the styling house was struggling to make a profit and that same year, Alejandro DeTomaso sold Ghia along with a large chunk of his company to Ford, which was looking for that exotic Italian touch.
