Mazda CX-9 SUV Confirmed For Malaysia Next Year
Just as CX-9 SUV did nine years ago when it was first shown to Malaysians, this 2nd generation large Mazda SUV redefines expectations, aiming for no other target than to be uncompromising in any aspect a family may need or an individual may desire.
When developing the 2016 Mazda CX-9, Mazda’s marketing, design and engineering teams surveyed hundreds of previous, current and in-market drivers, developing a vision of how to focus its efforts to create a vehicle around the personal values of those driving it.
The driver of CX-9 was seen to be a caring husband or wife, a high-achiever, a busy parent-and, still, an individual with his or her own needs and aspirations. CX-9 was developed to indulge personal desires while satisfying rational needs for a practical, all- weather family vehicle.
KODO’s strength lies in proportion-a long hood, swept greenhouse, large wheels and short overhangs convey stability and a contained sense of energy ready to be unleashed. At 199.4 inches (5065mm) long, CX-9 is 1.2 inch (30mm) shorter than its predecessor, but its wheelbase has been stretched 2.2 inches (55mm), benefiting passenger leg room as well as entry to and exit from the rear.
Mazda CX-9 carries shorter overhangs on both ends-2.3 inches (59mm) shorter up front and 1 inch (25mm) shorter in the rear-with its A-pillars shifted back 3.9 inches (100mm), lengthening its hood and adding a sense of strength through proportions.
Housing large wheels- 18 and 20-inch wheels-CX-9’s tapered fenders are pushed to the edge of its body, giving the vehicle a wide, trapezoidal stance.
The smooth lines start up front with a bold, five-point grille with double bars. They’re flanked on either side by standard low- and high-beam LED headlights. The bold grille introduces a strong lower body and sleek upper body that elevates KODO, introducing sleek curves that provide a premium appeal in a segment awash with convention. The overall effect is one of purity, simplicity and Japanese beauty.
Designed to make CX-9 look as though it were carved from a single ingot of steel, Machine Gray is the newest signature color from Mazda, complementing CX-9’s surfacing.
In order to do achieve its look, perfect, blemish-free panels are a necessity, which come as a result of ultra-precise stamping and assembly. Paint is applied in a primer, a black base coat to add depth, the Machine Gray color and, finally, a clear coat-all spaced out such that the paint has time to set in a precisely climate-controlled environment. But that does little to describe the engineering complexity behind such a breathtaking color.
Machine Gray has a depth and luster usually reserved for concept vehicles, using principles and processes adopted from lessons learned when developing signature color Soul Red.
Additionally, Mazda CX-9 will be available in Soul Red, Snowflake White Pearl, Sonic Silver, Jet Black, Deep Crystal Blue and Titanium Flash (colors may not be available in all markets).
SKYACTIV-G 2.5T Turbocharged Engine
However, Mazda’s latest engine, the SKYACTIV-G 2.5T, is a realization of excellent real- world and catalog fuel-economy as well as spry acceleration, featuring a host of technological advancements to achieve this goal.
One piece of technology is Mazda’s Dynamic Pressure Turbo, the world’s first turbocharger with the ability to vary the degree of exhaust pulsation depending on engine speed. The system routes engine exhaust to the turbocharger’s turbine through smaller ports at low rpm. It works similarly to when one might place his or her thumb on a garden hose, creating a strong amount of pressure through a smaller outlet. This allows the turbocharger to spool up quickly, creating instant boost-up to 1.2 bar (17.4 psi) of pressure. When the engine is in the heart of its rev range, it opens up secondary valves, allowing for greater amounts of exhaust gas to pass through the turbocharger. The system is complemented by the 2.5-liter engine that already benefits from more torque at atmospheric pressure than a comparable 2.0-liter by virtue of its size.
Further assisting CX-9 to maximize turbocharger efficiency is a 4-3-1 exhaust. With this setup, the exhaust from the middle two cylinders (2 and 3) is joined into a single port, while the exhausts from the outer cylinders (1 and 4) each have their own ports. These three ports come together at the entrance to the turbocharger’s exhaust side, where there is always one exhaust pulse arriving every 180 degrees of crankshaft rotation. Not only does this very compact manifold keeps the exhaust pulses separate for maximum energy extraction, it also harnesses each exhaust pulse to suck the residual exhaust from the adjacent ports.
That only tells so much of the story. In order to increase fuel-efficiency, SKYACTIV-G 2.5T employs the efficient combustion of Mazda’s SKYACTIV-G 2.5-liter engine and marries it to a cooled exhaust gas recirculation (EGR) system, which helps prevent burning excessive amounts of fuel when the engine is running at higher temperatures. In many turbocharged cars, heat is controlled through adding more fuel to the combustion chamber; Mazda’s cooled EGR reduces the need for that.
While Mazda sees no discernible benefits on regulated test cycles from this technology, it benefits the consumer through real-world gains.
The cooled EGR helps bring engine temperatures down from approximately 500 degrees C (932 F) to just over 100 degrees C (212 F), allowing SKYACTIV-G 2.5T to operate with a compression ratio of 10.5:1-one of the highest numbers of any gasoline-powered, turbocharged engine.
The net result: 420Nm of torque at a low 2,000 rpm and 250 horsepower at 5,000 rpm. At 55 mph (88 km/h), a driver needs just 18 horsepower to maintain speed on flat roads with a front- wheel-drive model-a four-horsepower reduction versus the outgoing model, illustrating reduced friction in all parts of the driveline and enhanced aerodynamics.
