Infiniti Q50 (2013) teaser video of new sports saloon

The first car to emerge under Infiniti's new naming structure will be the Q50, due at the Detroit motor show in January 2013. The Q50 will replace the rare-groove G37 saloon, and attempt to propel Nissan's luxury arm into the hotly contested small exec saloon battleground. Infiniti Q50: the first details While the Q50 will fight established posh saloons like the BMW 3-series and Mercedes C-class, it'll also spawn a Q60 two-door coupe and cabriolet range, like its German rivals.

Audi A3 Saloon arrives in the UK from £24,275

The Audi A3 Saloon (pictured) arrives in the UK Audi isn’t afraid of covering every possible niche in its ambition to be the world’s top ‘Premier’ marque, so we now get a third body shape for the new A3 – the Audi A3 saloon. Designed to sell in markets that prefer a traditional 3-box car to a hatch – like the US and China – Audi still believes there’s a market for an A3 with a boot in the UK, so the new A3 Saloon arrives on sale with a choice, at least initially, of three engines – two petrols and a diesel. Cosmetically, apart from the addition of a boot, the A3 Saloon gets more pronounced curves, bigger wheel arches, new shapes on the bonnet, new bumper, new lights and a boot spoiler.

Preview: Porsche Panamera

After what has already been the most drawn-out model introduction ever (the initial Porsche sketches of the new model having been revealed in 2005), Porsche has finally released the first official rendering of its forthcoming Panamera sedan, set to be launched in 2009. Though the plan view doesn't show much of the new Porsche's design, the company says the features will 'include a wide and low body offering dynamic proportions and muscular design'. But while the grand tourer will have a 'compact overall look', the interior space is claimed to offer a brand-new experience of roominess, with two single seats and generous headroom at the rear allowing adults to sit in comfort.
