New 2015 Ford Focus ST revealed – Diesel ST gets 182 bhp

The new Ford Focus ST arrives – and there’s a diesel version too. Following a tease for the new Ford Focus ST earlier this week, Ford has now revealed the new ST – and the ST diesel – as Ford’s refreshed ST heads to the Goodwood Festival of Speed for its public debut today.

The Technology Behind F1 Cars: Aerodynamics [w/Video]

Ferrari's latest video in its ‘Discover the technology of Formula 1' YouTube series sees Scuderia Ferrari's deputy design chief Simone Resta focusing on the chassis and side pods' design and its effect on the aerodynamics. This video follows two episodes, the first of which introduced viewers to the concept of aerodynamics – which is the subject of the series' first part – while the second took a look at the design and effect of the car's front wing and nose.

Enthusiast 3D prints an Aston Martin DB4

New Zealand enthusiast Ivan Sentch is in the process of 3D printing a 1961 Aston Martin DB4.

Using a Nissan Skyline as a donor car, he'll make a fiberglass mold of the print and hopefully transform this thing into a drivable, street-legal car for a fraction of the cost of an authentic DB4.
