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.

Corvette Central: Revamped C7, radical mid-engined C8 in GM's plans

General Motors is mulling a radical re-engineering for the Chevrolet Corvette, centered on a more fuel-efficient, mid-engined V6 powertrain, a lightweight alloy body and a more compact footprint. The idea is to re-energize GM's ambition for the Corvette, with fundamental changes that will make it into a contemporary global supercar. The changes are penciled into GM's product plan for the next major model change, the C8, with an on-sale date around 2016.

Porsche Macan means 1,000 extra jobs at Porsche

The Porsche take on the Audi Q5 – the new Porsche Macan – looks set to be Porsche’s biggest selling model ever and means 1,000 new jobs at Porsche. The ‘baby’ Cayenne – the Porsche Macan – is Porsche’s take on the Audi Q5 and a model that looks set to take Porsche’s sales to levels undreamed of a decade ago (pre-Cayenne). But although the Macan is based on the Q5 – just as the Cayenne shares its underpinnings with the Q7 and Touareg – Porsche say it will still be a red-blooded Porsche – the ‘Sports’ car in its sector – when it goes on sale later in 2013, so we don’t expect to see a lethargic eco diesel under the bonnet, although a fettled 2.0 litre TDI is highly likely.
