Mazda Motor Corporation unveiled the all-new Mazda CX-5 crossover SUV. The fully redesigned model, on display at AutoMobility LA, will be launched in Japan in February before being rolled out to global markets.
The global powertrain lineup comprises the SKYACTIV-G 2.0 and 2.5 gasoline, and SKYACTIV-D 2.2 diesel engines. Mazda announced it will offer the SKYACTIV-D diesel in North America from the second half of 2017. This will be Mazda’s first diesel engine model in the North American market. The CX-5 also adopts G-Vectoring Control, the first of the SKYACTIV-VEHICLE DYNAMICS vehicle motion control technologies. (Earlier post.)
Launched in 2012, the CX-5 was the first new-generation model featuring SKYACTIV technology and KODO design. It has since grown into a core model that is sold in more than 120 countries and accounts for approximately one quarter of Mazda’s global sales volume. It has won around 90 awards worldwide, including 2012-2013 Japan Car of the Year.
The engines in the new CX-5 are paired with either the six-speed SKYACTIV-DRIVE automatic or six-speed SKYACTIV-MT manual transmission. Also available is Mazda’s predictive i-ACTIV AWD system, which helps prevent the front wheels from slipping. The system employs synthetic oil that reduces energy losses throughout its operating temperature range by maintaining its low viscosity, even in extremely cold temperatures. It also reduces resistance by adopting ball bearings for all its power take-off and rear differential unit bearings.
G-Vectoring Control adjusts engine torque in response to steering wheel action to deliver unified control over lateral and longitudinal acceleration (G) forces and optimizes the vertical load on each wheel. GVC is particularly effective in SUVs, which can be prone to generating lateral forces due to their relatively high center of gravity. It achieves high levels of both vehicle responsiveness and stability, while also helping to reduce sideways sliding of the cabin occupants’ bodies and deliver a comfortable ride.
In addition to using a column-type electric power steering system, the new CX-5 adopts rigid steering mounts that heighten its linearity and steering rigidity.
The new CX-5 suspension system uses MacPherson struts in the front and a multi-link system in the rear. Increasing the diameter of the front damper pistons and adopting liquid filled bushings for the front suspension suppresses the floating sensation experienced by the driver and the unpleasant vibrations all cabin occupants feel when the vehicle is subjected to roll.
The brake system employs ventilated discs in the front and solid discs in the rear. The new CX-5 also newly adopts Mazda’s Auto-hold function, which keeps the car stopped even after the driver lifts their foot off the brake pedal.
In the body, a 15.5% increase in torsional rigidity over the previous model reduces flexing that might otherwise slow response to the driver’s steering actions. Increased application of ultra-high-tensile steel includes the adoption of 1,180MPa steel on the A-pillars and 980MPa steel on the side sills and B-pillars.
NVH. To realize a quiet cabin environment that enables occupants to enjoy stress-free conversation while driving, Mazda put particular effort into reducing low-frequency road noise heard when traveling on roads with coarse surfaces, as well as high-frequency wind and tire noise heard when traveling at higher speeds. Compared to the previous model at a cruising speed of 100km/h (62mph), the new CX-5 achieves approximately 10% clearer conversation levels within the cabin and reduces noise by approximately 1.3dB when traveling on rough road surfaces.
Aerodynamic parts strategically positioned on the body where they will be most effective and duct-shaped openings within the front grille realize excellent aerodynamic performance.
Further evolved i-ACTIVSENSE. Mazda Proactive Safety is a comprehensive approach to maximizing the range of conditions in which the driver can operate the vehicle safely and with greater confidence.It aims to help support true driving pleasure for every customer.
Newly added active safety functions and features enable Mazda’s i-ACTIVSENSE advanced safety technologies to lend yet greater assistance to the driver in identifying potential risks early on, and to reduce chances of damage or injury. This includes the introduction of new technologies for supporting awareness and safer driving. Enhancements to the passive safety features include improved efficiency of the multi-load path structure on Mazda’s high-strength SKYACTIV-BODY, and increased use of ultra-high-tensile steel.
The new CX-5 is equipped with the latest evolution of Mazda Radar Cruise Control (MRCC), which can follow the vehicle ahead from a standing stop, and with Traffic Sign Recognition (TSR), which reads speed limit and other road signs and displays the sign’s message on the Active Driving Display.
The SKYACTIV-BODY effectively absorbs and disperses impact force to suppress cabin deformation. In addition, the strengthened A-pillar section and expanded use of high-strength materials reduces weight and achieves a higher level of collision safety.
A complement of safety equipment and features helps provide reassurance in the event of a collision. Adding polypropylene foam to the inside of the headrests and optimizing the mounting method for the seatback frame improves the head impact mitigating structure of the front seats. Structures under the hood and in the front bumper help mitigate injury to a pedestrian’s head or legs.
