Already spotted testing last year, the lighter, more powerful version of the Lamborghini Huracan – the Huracan Superleggera – has been spotted testing in cold weather in Northern Sweden, as caught by our spy photographers.

The test mule spotted here appears to be largely the same as before when it was circuit testing, but with one change: the wheel hubs on this mule are of the centre-locking variety instead of the standard, five-lug layout on the previous test mule and the standard Huracan. Could this point to a bespoke suspension setup for the Superleggera? Time will tell.

As before, the Huracan can be expected to make improvements over the standard car in weight and in engine output; where the Gallardo Superleggera LP570-4 managed a 70 kg weight saving over the standard Gallardo, a similar weight loss margin is possibly in order, while a similar increase in engine outputs of just under 10% in power and torque can be expected too.

While interior details and images have yet to surface, a similar approach as before can be expected: lightweight, fixed-back bucket seats, more carbon-fibre and Alcantara to be found in the interior, with details such as uprated suspension and brakes also expected to feature in the more focused V10 Lamborghini.

The open-topped version of the performance-focused Huracan also makes its appearance here with its fixed-roof twin, and like that car, it features a host of exterior body features for more aggressive aerodynamics – deeper front splitter and rear diffuser, while the tall rear wing has pronounced angle of attack and the twin exhaust pipes are now mounted higher and more centralised.

The soft-top Superleggera can also be expected to wear the Spyder Performante name, given that the nature of its roadster body can’t offer weight savings as significant as those on the coupe. With both the coupe and the roadster spotted together here, the duo can be expected to make their debuts at the 2017 Geneva Motor Show.
