The new addition to the second generation R8 range can convert to sun-seeking mode in just 20 seconds, leaving occupants to enjoy the elements to the increasingly rare tune of a naturally aspirated V10 soundtrack. The basic format may be familiar, but the ground up rework of the R8 Spyder brings it very much up to date not only by adding more power and a 50 percent uplift in torsional rigidity, but also sophisticated new features including the fully digital Audi Virtual Cockpit, the Audi smartphone interface and Internet-based Audi Connect services.

The key point of differentiation between Coupe and Spyder R8 models is of course the lightweight, fully automated cloth hood, which can be activated at speeds of up to 50km/h and is slickly concealed beneath the sculpted integral cover, or reattached to shield occupants from a sharp shower, in just 20 seconds. The rear window, sunk into the bulkhead, can also be retracted and extended at the touch of a button.

The strong backbone of the new R8 Spyder is the newly developed multi-material Audi Space Frame, which incorporates an intelligent mix of aluminium and carbon fibre that helps to keep dry weight down to just 1,612kg. The inherent strength of the concept is evident in the fact that torsional rigidity has increased by over 50 percent compared with the previous model, helped by Spyder-specific body reinforcements primarily in the sills, A-pillars and windscreen frame.

To propel this light yet impressively rigid shell as effectively and efficiently as possible, the latest naturally aspirated V10 works with a fast-acting seven-speed S tronic transmission and a newly designed quattro drive system. The upgraded power plant adds advanced features such as dual injection to optimise response and a freewheeling mode, which enables it to 'decouple' whenever possible to improve fuel economy.

869bhp of power and 540Nm of torque at 6,500rpm deliver phenomenal road performance, with the 0-100km/h sprint taking just 3.6 seconds on the way to a top speed of 317km/h, but the latest R8 Spyder is also capable of returning up to 10.24km/L, corresponding to 277g/km of CO₂.
