2010 Mazda3 MPS (European Spec.) Overview Part III – Chassis and Safety

An Evolution of Driving Fun
The body and chassis of the new Mazda3 MPS are combined with advanced engine torque control to deliver an evolution of driving pleasure. Compared to the all-new Mazda3, the new MPS is engineered with a stiffer body shell and special reinforcements, a modified suspension and larger tyres. These translate the car’s high-performance power and torque to the road in a way that makes it easy to control and fun to drive on a daily basis. It also possesses one of the segment’s most comprehensive safety packages with new active safety technologies.

New Mazda3 MPS Body Shell – Stiffer, Lighter, Stronger

A new-generation body shell is used for the new MPS, with 17 percent more high-tensile steel and special reinforcements. These include a special support member inside the front cowl member gussets that strengthens the joints between the rear suspension towers and rear floorboard, and a new and larger tunnel member. Body rigidity compared to the previous MPS is drastically improved by these measures – 15 percent for body hysteresis and a 41 percent improvement for liftgate diagonal displacement.

Suspension and Steering Updates – Improved Straight-Line Stability
The new high-performance Mazda3 MPS suspension has the same basic layout as the hatchback version – front MacPherson struts and a multi-link system at the rear – with newly-added components and special settings. The coil spring rates, for instance, are modified for the new MPS and special dampers with increased damping strength are introduced. Together they contribute to more control by providing increased roll stiffness. Also special to the MPS are larger diameter stabilizers with an increased span for the stabilizer mounts, which increases roll linearity.

Like the normal Mazda3 line-up, the new MPS has three highly-rigid steering gear mounts (instead of the previous model’s two gear mounts) which deliver improved response to steering commands compared to the previous-generation MPS. Special Dunlop 225/40 R18 tyres developed exclusively for the new flagship model are standard. They are wider (from 215 to 225), have more rigid sidewalls and better damping strength than those of the previous model. This is combined with an electro-hydraulic power-assisted steering system specially tuned to react more precisely to vehicle speed. Taken together, these special features mean improved straight-line stability, and a flatter ride with fewer undulations during sporty driving manoeuvres.

NVH – More Comfort on a Daily Basis
The new Mazda3 MPS is not only more controllable and fun to drive, it is also more comfortable. The sporty compact’s dual exhaust pipes are all-new and 10 dB quieter above 5,000 rpm than the previous model’s exhaust. They now produce a deep sporty sound that is more refined compared to the single exhaust of the previous version. On the inside, passengers are now pampered with some of the segment’s lowest sound levels. The new Mazda3 MPS has 1.2 dB less road noise, and wind noise has been reduced by 6 percent compared to the previous model.

Safety – Robust Brakes and new Active Safety Technologies Standard

A strong braking system is needed for a sporty compact as powerful as this. The ventilated front disc brakes are 20 mm larger (320 mm) than the normal line-up, while the solid discs at the rear share the same large size (280 mm). It also features a 8+9 inch tandem brake booster with a large, 1-inch (254 mm) master cylinder. These components help make the new Mazda3 MPS more controllable by realizing powerful and stable braking.

New for the Mazda3 MPS is a long list of special active safety technologies as standard that help the driver avoid an accident before it might occur. Electronic brake assist replaces the former mechanical assist, and works with four-wheel ABS and dynamic stability control (DSC), all standard equipment. A new adaptive front lighting (AFS) system with pivoting bi-xenon headlamps illuminates the curves at night (standard or option depending on market). Drivers always know the status of their tyre pressure as well, with the introduction of a new tyrepressure monitoring system (TPMS, standard in most markets).

A rear-vehicle monitoring system (RVM) that warns the driver before he changes lanes when a car is approaching from the left or right rear, or is in the blind spot, is also standard, as is an emergency stop signal (ESS) that flashes the hazard lights if the driver suddenly and strongly brakes in traffic. A parking sensor system makes it easy to park in tight spots (also standard in most markets).
