Our spies have caught the Audi A1 undergoing a final round of testing before it is unveiled to the media next week.

While there isn't anything new to see - since the car was already caught undisguised during a photo shoot with Justin Timberlake - we can get a glimpse of the LED daytime running lights and 'contrasting curve' roof.

Inside, the car will feature "a wide range of possibilities for individual designs" including Wasabi Green accents. Elsewhere, the dash has been designed to resemble an "aircraft wing with the engines (aka air vents) suspended from it."

Under the hood, engines options will likely include a 1.2-liter TFSI with 63kW (86 PS) and 160 Nm, a 1.4-liter TFSI packing 90kW (122 PS) and 200 Nm, and a 1.6-liter TDI churning out 77kW (105 PS) and 250 Nm of torque. If that doesn't sound very interesting, Audi is expected to unveil the S1 in February 2011. According to initial reports, the S1 will feature a 132kW (180 PS) engine and a seven-speed S-Tronic transmission.

The A1 will go on sale this summer and Audi predicts 80,000 units will be sold by the end of the year.

Stay tuned to WCF for full coverage of the A1's media unveiling next week.
