Concept Car of the Week: Alfa Romeo BAT 7

This week sees the Concept of the Week title go to Alfa Romeo and Bertone for their collaboration on the Alfa Romeo BAT 7, the second addition to the BAT series that began in 1953 and finished in 1955. First seen at the 1954 Turin motor show, this wildly futuristic ‘dream' car came about after Alfa Romeo contacted Giuseppe "Nuccio" Bertone of the Bertone carrozeria to commission three concepts with the lowest possible drag coefficient. The cars were named BAT for "Berlinetta Aerodinamica Tecnica." Built upon the Alfa Romeo 1900 chassis, the BAT cars featured large rear bumpers and curved fins, and the concepts achieved a drag coefficient of just 0.19 - an impressive result.

Bonhams' Greenwich auction will show Italian rarities

The biggest star of Bonhams' seventh annual Greenwich auction will be the 1975 Lamborghini Countach LP400 Periscopica shown above, a pristine early example of the legendary wedge with a single owner and less than 10,500 miles -- its roof carried a groove cut into the sheetmetal that allowed light to hit the rearview mirror, providing a still-laughable semblance of rearward visibility. Of course, the door is always preferable. Just 158 LP400 Countachs were ever produced, before the firm moved on in 1978 to the outrageously styled LP400S.

Jaguar F-Type Coupe caught on video at Nurburgring

The Jaguar F-Type Coupe (pictured) testing at the Nurburgring The new Jaguar F-Type is a fine looking car, but the F-Type Coupe looks set to be the real looker, and we shouldn’t have to wait too long before the coupe hits a motor show (probably Frankfurt in September). Ahead of that reveal – with a likely on-sale date of early 2014 – Jaguar are out playing with the F-Type Coupe at the Nurburgring, blatting it round the ‘Ring’s unforgiving surfaces and bends to shake the last niggles out before launch. This particular F-Type is undoubtedly the V8 S – which we expect will get the same 495bhp output as the V8 S Roadster – and it sounds great; a wonderful V8 roar as it pounds round the track.
