First Sight: Holden Torana concept

Holden has stolen the limelight at the opening of the Australian International Motor Show in Sydney, unveiling a ground-up concept car dubbed the Torana TT36. The concept revives a famous Australian nameplate from the 1970s - appropriate since, like the original Torana, it features rear wheel drive and a six cylinder engine. That's where the similarities end, however, as the new Torana's engine is an experimental 280kW/490Nm twin turbocharged version of the new global V6 Holden has begun manufacturing for various parts of the GM world and which will eventually be used by Alfa Romeo.

In pictures: backstage at 72nd Goodwood Members’ Meeting

It was Glorious Goodwood on the last weekend of March, for Lord March’s latest classic motorsport event – the 72nd Goodwood Members’ Meeting. It’s one of only two race weekend to be held at the circuit since it reopened in the late 1990s: Lord March wants it to complement the world-famous September Goodwood Revival and become known as a classic in its own right. The difference here is that, as its name suggests, it’s a members-only event: only Goodwood Road Racing Club members can buy tickets.

Porsche Panamera upgrades (2010) first details

The 493bhp Porsche Panamera Turbo is about to get even more powerful: Porsche has released details of a new range of upgrades available on the Panamera, including a £14k Powerkit pack. The Powerkit – as its name suggests – delivers an increase in power (and torque) over the standard car, and is exclusively available on the Panamera Turbo. The Panamera Turbo left us a little underwhelmed when we put it through its paces a year ago, chief issues being the packaging, styling and ergonomics.
