Aston Martin Vanquish Volante (2013) at Frankfurt motor show

New models are coming thick and fast in Aston Martin's centenary year: here’s the drop-top Aston Martin Vanquish Volante. The soft-top flagship is the first convertible Aston with a carbon body, making the stiffest and most powerful drop-top it has ever built. Its 565bhp drivetrain has been taken straight from the Aston Martin Vanquish coupe – the most powerful Aston to date – but the Volante adds 105kg and an extra £6000 for a starting price of £199,995.

Porsche Panamera Junior (Porsche Pajun) still on the cards

Porsche Panamera Junior (Porsche Pajun) still on the cards The idea that Porsche would build a saloon to sit below the Panamera have been on the cards almost as long as the Panamera has been with us. Back in early 2011 we reported that a Porsche Pajun was being planned for 2016 and in 2012 a Porsche source confirmed that a baby Panamera was under development with plans to get it to the market in 2015. Now, Porsche boss Matthias Muller has all but confirmed to Autocar that the ‘Pajun’ is under serious consideration, although the logistics of building a ‘volume’ model like the Pajun is a tough logistical ask as Porsche has just gone through that exercise to produce the Porsche Macan.

SEAT Leon FR 2.0 TDI 184 PS costs from £22,075

The SEAT Leon FR 2.0 TDI 184 PS (pictured) arrives in the UK from £22,075 The 2013 SEAT Leon arrived at the Paris Motor Show last year as the Spanish take in the VW Golf. And now the SEAT take on the Golf GTD is in the UK – the SEAT Leon FR 2.0 TDI 184 PS. With a dose of Spanish flair making the SEAT a more flamboyant, and appealing, car than the Golf, it comes with the same 181bhp 2.0 litre diesel as the GTD, offering 0-62mph in 7.5 seconds and 67.3mpg.
