Over the past week, the automotive world was graced with many photos of hyper-exotic cars showcased at Pebble Beach. With the week long festivities over, many of the European sourced cars are now conveniently going on North American tours for both private and public showings. We have just learnt that two of the highlights from this year’s Pebble Beach concours will be going North of the American border to Vancouver’s Luxury Supercar Weekend‘s show.

Due to strict US safety regulations, the delivery of the Huayra was delayed for Pagani’s American customer base. Through recent compliance to airbag specifications, Pagani hopes to have units of their hypercar on American soil by the end of the summer. The Pagani Huayra presented at, Monterey, Pebble Beach this year was the exclusive to one unit, Carbon Edition variant. Instead of having painted external panels, this limited edition Huayra opts for fully exposed carbon panels. This will mark the first time the Italian hypercar manufacturer to step foot in Canadian soil.

The second highlight from Pebble Beach to be displayed at Luxury Supercar Weekend will be a new limited edition variant of the Bugatti Veyron Vitesse. The Bugatti Veyron Grand Sport Vitesse Jean-Pierre Wimille Edition is unlike any other already exclusive Bugatti Veyron as it is the first of six “Les Légendes de Bugatti” to be made over the coming months. This specific edition, a variant of the fastest production convertible, will have a limited run of three units. The Bugatti convertible will sport a mixture of exposed carbon fibre and a blue finish justifiably named Wimille Bleu.

On the tuning frontier, a new company based in Vancouver, Attivo Designs is set to globally debut for the first time their dynamic spoiler oriented kit. The new company boasts their kit not only has form but a critical aspect of function as well. Contrary to any of Attivo’s competitors, their dynamic spoiler stabilizes and aids in braking when needed at high speeds similar to those dynamic spoilers found on standard Bugattis, Aventadors, and Paganis.

Attivo’s engineering oriented CEO, Robbie Dickson, went in to extensive detail of their marquee Project Inizio kit’s dynamic spoiler.

Above 80 mph the Attivo rear wing acts as an air brake by increasing the coefficient of drag, when the brakes are applied. The wing adjusts itself to a 55-degree angle of attack in less than 1 second. This air braking system provides almost 0.7G of braking force, or roughly as much as the brakes of an ordinary passenger car, when deployed at 150mph.

The drag coefficient of Attivo’s wing comprises the effects of two basic contributors to drag with respect to air brake wing design; Lift-induced drag increasing the Angle of Attack increases lift induced drag and form drag or pressure drag arrises because of the form of the wing once deployed into its breaking position. The general size and shape of the wing when it’s deployed in to its air brake position is perhaps the most important factor in form drag. The benneficial aspect of form drag for the Attivo air brake wing design is that it rises with the square of speed, and thus becomes more efficient as a braking system at higher speeds.

The air brake system is deployed via two linear motion control actuators. These compact actuators convert rotary motion from their internal DC motor into linear motion, which are connected directly to the air brake wing. Each actuator has built in safety limit switches for end of travel power cut-off and fast smooth motion for quick deployment and retraction of the wing.
