Two Club Sport concepts start off the lineup, with both Mazda 3 and 6 models getting bespoke paintwork and subtle bodywork changes.
The Club Sport 6 concept is fitted with a 2.2-litre SkyActiv diesel engine, with a power output of 173bhp and 310lb ft of torque. That same engine has already seen use in motorsport in the US.
The exterior of the concept has a custom-designed aerodynamic bodywork kit which features front, side and rear diffusers alongside a rear spoiler. The concept sits on bespoke tyres and 20-inch wheels. Mazda has also upgraded the suspension system with performance pars, as well as adding racing brakes and a new racing exhaust system.
Meanwhile, the Club Sport 3 Concept features many of the same enhancements as the 6 but gets more robust design features. The exterior is finished in bespoke paintwork with club sport graphics, with metallic exterior trim in places. A new aerodynamic body kit has been added, which will be available worldwide for all new Mazda 3 models in 2014.
The Club Sport 3 concept is powered by a 2.5-litre SkyAtiv-G petrol engine and attached to the same six-speed manual transmission used in the CX-5 compact SUV. A new limited-slip differential has also been fitted to provide more torque from the engine. The concept also uses upgraded suspension, braking and exhaust systems with bespoke 20-inch wheels.
Inside, the concept has a red leather interior with black leather trim.
Alongside the two Club Sport concepts Mazda is also showing its Vector 3 concept car. Again based on the Mazda 3, the Vector 3 features a new take on Mazda's Kodo design language with new paintwork. It sits on a pair of 19-inch wheels, and Mazda says it has again upgraded the suspension and braking systems.
Finally, Mazda also has its Ceramic 6 concept on display. Based on the Mazda 6, the concept features similar styling to the Vector 3 concept, but features bespoke paintwork with silver vinyl accents. The interior is again coated in leather with new front seat inserts and various trim upgrades.
