GM's Ed Welburn walks Jay Leno through the Elmiraj concept's design [w/Video]

General Motors' vice president Global Design Ed Welburn stars in the latest of the 'Jay Leno's Garage' YouTube series, running the talk-show host through some of the new Cadillac Elmiraj concept's design features and what it means for the brand's future. We get a look at all the classic Cadillac design cues such as the vertical headlamps and tail lamps as well as the central hard crease that Welburn says is "important in every Cadillac". Leno and Welburn then move onto the Elmiraj's features, such as the large doors' integrated handles and the slimmer A-pillars before a more in-depth look at one of the concept's most striking features – the grille.

Alfa Romeo Giulietta facelifted for the 2013 Frankfurt Motor Show

Alfa Romeo today only sells two regular cars, the MiTo and Giulietta. The family hatchback Giulietta is its most profitable – and also its best – and so to ensure it still has at least some appeal alongside the Volkswagen Golf and Ford Focus that outclass it, Alfa has facelifted it for the 2014 model year. It’s a very discreet and low-effort facelift, but the firm still hopes it’s just enough to keep the family five-door ticking over.

Hyundai’s hydrogen-powered ix35 turns its hand to growing fish and food

The Hyundai ix35 FCEV Fuel Cell Farm outside the London Design Museum Hyundai PR do like a slightly left-field take on raising awareness of Hyundai’s products (although they usually involve animals, children, fashion or shopping), so a Hyundai ix35 FCEV turned in to a fuel cell farm should come as no surprise, nor that they parked it outside London’s Design Museum for a bit of extra profile. With the help of sustainability creatives (who’d have thought there was such a business?) Something & Son, Hyundai has created a Fuel Cell Farm (well, depending on your definition of how big something growing has to be to be called a farm) that uses the emissions from the ix35 FCEV as its water source. The setup takes the water from the ix35 and feeds it in to the fish tank, the fish do what fish do and the aquaponics gubbins takes that and uses it as food for the plants.
