The Audi R8 Competition is the most powerful R8 variant to-date and will make its official debut at this year's Los Angeles auto show.

Behind the passenger cell, the R8 Competition features an uprated version of Audi's 5.2-litre V10 engine. With 425kW of power on hand, it has a 6kW advantage over the limited edition LMX and 21kW more power than the V10 Plus.

It's unknown, at this stage, how much torque the R8 Competition has at its disposal, but both the LMX and V10 Plus generate 540Nm.

With the standard seven-speed dual-clutch transmission and sports exhaust, Audi claims that the R8 Competition is good for a 0-60mph (0-97km/h) time of 3.2 seconds and a top speed of 320km/h. By way of comparison, the LMX also has a top speed of 320km/h.

Said to be inspired by the R8 LMS race car, the R8 Competition features a set of matte black carbon fibre modifications, including a fixed rear wing, side blades, wing mirror caps, highlights on the centre tunnel, rear diffuser and front spoiler.

The R8 Competition rides on gloss black 19-inch alloy wheels clad in 235/35 rubber up front and 305/30 tyres at the rear. Stopping power comes courtesy of ceramic brakes finished off with red brake calipers.

With the second-generation R8 expected to debut some time in 2015, the R8 Competition will have a strictly limited production run. Just 60 units will be sold throughout the United States; we're waiting to hear back from Audi Australia as to whether any R8 Competitions will be winding and wending their way down under.

The R8 Competition's title as the fastest and most powerful R8 may not be long lived. Earlier this month our spy photographers spotted a camouflaged R8 in Germany with a taller rear wing and more aggressive body kit than the Competition.
