See craftsmen build the Maserati Alfieri

At Geneva earlier this month, Maserati debuted the Alfieri concept, a love letter to Maserati's first 100 years and a preview of the next few years, if not the next 100. Here, design chief Lorenzo Ramaciotti shows how the Alfieri -- named after one of the five Maserati brothers -- was inspired by the 1954 Maserati A6GCS/53, as previously threatened, especially in the proportions. But like any car, the key is always in the proportions.

GM continues work on fuel-saving engine technology

Sometime in the next decade, you might be able to enjoy some of the benefits of a diesel without driving one. A technology called HCCI improves fuel economy 15 percent and releases fewer emissions by using a combustion process similar to what is used in diesel powerplants. General Motors continues work on the project, which could be applied across a range of engine sizes and used with other advanced fuel-saving technologies to help the company comply with the proposed new mileage and emissions targets announced Tuesday by President Barack Obama.

Jaguar XF Sportbrake Price & Model lineup plus new XF engine options

The Jaguar XF Sportbrake will cost from £31,940 and the XF saloon will  get the new V6 Supercharged 3.0 litre engine for 2013. It’s taken quite a while to get a Jaguar XF Sportbrake price from Jaguar’s bean counters, but they’ve finally decided the entry price for an XF Estate will be the XF Sportbrake 2.2 Diesel SE Business at £31,940, rising to £51,505 for the XF Sportbrake 3.0 Diesel S Portfolio – a premium of around £2.5k for the shed on the back. The XF Sportbrake gets a choice of two versions of the new 2.2 diesel – a 163PS and 200PS (which takes the place of the original 190PS version) – and two versions of the 3.0 litre diesel – 240PS and 275PS – all of which will also be offered in the 2013 XF saloon.
