Lexus has published official images and initial details on its LF-Ch concept car that will eventually give birth to a premium hatchback model aimed at the BMW 1 Series and Audi A3. Unfortunately the Japanese firm's lengthy press release is dedicated for the most part to the LF-Ch's exterior and interior styling. In other words, the usual design mumbo-jumbo you hear from most automakers and which we'd rather avoid repeating.

However, what Lexus does reveal is the concept model's exterior dimensions. With an overall length of 4,300mm (169.3-in.), a width of 1,790mm (70.5-in.) and a height of 1,400mm (55.1-in.)with a 2,600 mm (102.4-in.) wheelbase, the LF-Ch is roughly the same size as the Audi A3 Sportback (4,292mm in length, 1,765mm width, 1,423mm height and 2,578mm wheelbase).

The concept model features a full hybrid drivetrain meaning that unlike mild-hybrids, it can be driven in a fully electric EV mode. Lexus did not disclose any other details on the powertrain - or about anything else for that matter.

"The LF-Ch concept reaffirms Lexus's commitment to Europe, combining compact dimensions, stylish five-door, full hybrid technology and low emissions to satisfy the most demanding customer requirements and to appeal to a new, younger generation of customers," the company said in a prepared statement.

European buyers should expect to see a toned-down production version of the LF-Ch available with both conventional and hybrid powertrain options sometime towards the end of 2010.
