A concept previewing the Lamborghini Gallardo successor will allegedly be unveiled in September at the 2013 Frankfurt Motor Show.

Set to receive the Cabrera moniker, Lamborghini's entry-level model will adopt a lightweight carbon fiber and aluminum spaceframe structure when it arrives in production form next year. It's internally known as the LP724 and rumored to be 16mm longer than the outgoing model which means we should expect an almost 4500mm length. Height and width will remain just about the same as the current Gallardo, meaning it will be around 1165mm tall and almost 1900mm wide. A wheelbase increase is also expected to provide better comfort inside the cabin.

While initial plans were to use Aventador's platform, Audi forced Lamborghini to take a different path to coincide with the second-gen R8 due in 2015. In other words, the Gallardo successor and new R8 will share a lot of components, including the aforementioned lightweight carbon fiber and aluminum structure which will tip the scales at 198 kg (436 lbs) for Audi's R8, making it 24 kg (53 lbs) lighter than the all-aluminum structure of the outgoing R8.

The 2015 Audi R8 will have a 30mm longer wheelbase and is set to offer stowage space behind the seats. Since Lamborghini's new model will be slightly shorter, the structure will be an additional 3 kg (6.6 lbs) lighter at only 195 kg (430 lbs). Using CFRP and aluminum panels, the Gallardo successor will have a curb weight of less than 1,500 kg (3,306 lbs).

At its heart will be an evolution of the V10 5.2-liter naturally-aspirated engine which will produce almost 600 bhp (447 kW) and 400 lb-ft (541 Nm). It will be linked to a standard 6-speed manual transmission or an optional new dual-clutch, seven-speed automatic taken from the R8 as a replacement for the six-speed automated manual gearbox offered for the current Gallardo. Four-wheel drive will be standard, but special editions will get a rear-wheel drive configuration.
