The Suzuki Swift Sport is the performance flagship of the Swift model range and offers higher levels of tuning, steering and braking performance than the standard Swift on which it's based. The previous model first went into production in Japan in 2005 and in Hungary in 2006. The sporting experience and everyday practicality have earned many devoted fans in approximately 40 countries and territories around the world. The new Swift Sport has the same DNA as its predecessor, but reflects the concept of developing a refined sport compact from the new Swift that Suzuki launched in the UK in Autumn 2010. Befitting its status as the new performance flagship of the Swift model range, it reflects the pursuit of even better handling, driving performance, environmental compatibility and an uncompromising focus on quality. Overall, it offers a rewarding experience of Suzuki's sporting DNA. Suzuki plans to launch the new Swift Sport in a growing number of countries, beginning October 2011, with sales launch in the UK from early 2012. Exterior The new Suzuki Swift Sport's exterior design reflects the model's evolution towards a more sporting look. The ground-hugging form gives a sense of stability, the large front grille hints at the performance within and is flanked by big, distinctive finned fog lamp bezels that add even more sporting character. Aerodynamic parts exclusive to the new Suzuki Swift Sport control the airflow, suppress lift and give the car a lower visual centre of gravity. Newly developed high-intensity discharge headlamps with a metallic-grey coating as well as new design rear combination lamps heighten the sense of dynamism expressed by the exterior design.

The world's most significant celebration of the automobile takes place annually in Monterey, California. In 2009, it saw some of the most elegant, exclusive, and valuable vehicles ever produced in over 100 years of motoring, with Bugatti playing a prominent role. On the evening prior to the Pebble Beach Concours d'Elegance, the highlight of the event, the marque renowned for impeccable automotive solutions, aesthetics and driving dynamics unveiled a second model to the world - the new Bugatti Veyron Grand Sport with a unique removable roof In response to customer demand, significant modifications have been made to the vehicle's complex structure to make possible open-top driving, thereby adding a new dimension to this high-performance sports car. Incorporating a host of new and innovative safety and equipment features, it is the world's fastest and most exciting roadster. It is immediately recognizable as a result of its slightly higher windscreen, stylized daytime running lights, and lightweight, transparent polycarbonate roof. The main challenge in developing the new Bugatti Veyron Grand Sport with removable roof resulted from the unique structure of the fixed-roof Bugatti Veyron. An optimum combination of rigidity and lightweight engineering ensures the monocoque passenger cell of the original model is extremely strong while weighing an absolute minimum - it is a central element of the vehicle's structure. As the roof is an integral part of this, removing it meant the load paths had to be completely redesigned to maintain the vehicle's rigidity and crash safety, and to offer additional protection from side impacts and rolling.
