how large displacement becomes low fuel consumption test X-431 Diagun Acura RDX 3.5L

Acura RDX power and handling as a selling point, focus on SUV models used by the city. Equipped with a 3.5L V6 i-VTEC engine, not only dynamic, but also uses variable cylinder system, at the same time to ensure the power, the intelligent selection of cylinder number, in order to achieve the effect of reducing fuel consumption. Variable damping shock absorbers, also depending on the road conditions and automatically select the works to ensure that the handling of the Acura RDX. Equipped with the four-wheel-drive system, although weaker than the SH-AWD, but the advantage in fuel consumption. SUV, Acura RDX is a suitable driving fun.Acura RDX is a SUV, but it is not off-road capability as a priority, but rather concentrate on power and handling. This test drive article also focuses on users of RDX in power and hanging on the technology as well as driving experience. Acura RDX is equipped with a 3.5L V6 i-VTEC engine, maximum power of 204kw (277ps) / 6200rpm, maximum torque of 340N • m/5000rpm to have valve continuous variable technology and intelligent power management system (VCM) engine match 6-speed manual transmission.VCM intelligent power management system that variable cylinder system, the engine depending on driving status and road conditions automatically select the number of engine cylinder, 6-cylinder, 4-cylinder, 3-cylinder intelligent switching, which means that we in a hurry acceleration and cruise when the number of the cylinders of the engine work is not the same, to achieve the purpose of reducing fuel consumption, guarantee the required power premise. In actual driving, when we go through the congested city roads, smooth high-speed winding mountain road, VCM system does not automatically select the number of engine cylinders obvious feeling, and will not affect our driving, and driving an ordinary The car makes no difference.However, if the time curiosity Daihatsu want to take a look the few cylinders work when the engine is in the end, Acura RDX did not satisfy this curiosity, whether it is the LCD screen on the center console or dashboard trip computer, are unable to show the working status of the engine. The Acura RDX is a 6-speed automated manual transmission, gear number and there is no obvious advantage, in D Dangxia, not high daily driving the speed remained between 1500 Go to 2000 rpm, the speed at 120km / h , the speed is also a turn around in 2000. The S block speed there is a clear upward maintained at 2500 rpm When the throttle is increased, the speed increases the speed is very fast, it is easy to reach 5000-6000 rpm, power surge is no doubt.Adjustment of this transmission is very smart, and when we have the intention of overtaking or accelerating, the throttle slightly increase that speed will be raised soon, a steady stream of power will keep up. Manual paddles behind the steering wheel the same so that the winding mountain road, plus stop frequent downshifts the transmission response is very sensitive, with the very place of our various operations. Acura RDX McPherson rear multi-link suspension, and has adaptive variable damping shock absorbers, but this is not the electromagnetic suspension, but the increase in the main piston valve down the activities of the second piston valve . Working alone in a small road through bumpy, the main piston valve. Larger pavement through bumps, the second piston valve began to work, have a greater damping, and to ensure the handling.Acura RDX is equipped with four-wheel drive system is not set on the MDX SH-AWD, but a set of official called E-DPS real-time intelligent four-wheel drive (E-DPS REAL TIME AWD), the four-wheel drive system is a computer complete control, can not find any button that can intervene in a four-wheel drive in the car, according to road conditions, automatic torque allocation, up to 50% of the torque to the rear wheels. Acura RDX is equipped with four-wheel drive system is not set on the MDX SH-AWD, but a set of official called E-DPS real-time intelligent four-wheel drive (E-DPS REAL TIME AWD), the four-wheel drive system is a computer complete control, can not find any button that can intervene in a four-wheel drive in the car, according to road conditions, automatic torque allocation, up to 50% of the torque to the rear wheels.Although the set of four-wheel drive system on the RDX is not as good as the MDX's powerful, but the combination of RDX positioned itself, highlighting the highways and economic characteristics, equipped with this set of E-DPS real-time intelligent four-wheel drive is still very dissonant, through but without loss of economy. Impressive addition to the control and power noise noise reduction, the Acura RDX is equally impressive in the day-to-day on the road driving, the noise is very low, both road noise, wind noise, engine noise is not obvious, until on a high-speed, speed to 150mk / h noise will be obvious.Acura RDX interior depth of the two options, in control of the overall style and the Acura family control design using symmetric and can not find any problem in workmanship and selected materials. The three Acura RDX leather steering wheel, covered with a variety of multi-function button on the steering wheel, you can control the volume, phone, cruise and other functions. Back and forth up and down four manual adjustment steering wheel with paddles behind the steering wheel comes with manual shift. Moderate size of the steering wheel, leather wrapped feel good.Above the center console is an 8-inch LCD screen, operate by the knob on the center console, the whole operation is very smooth, the interface design is relatively simple, the operation is not complicated. Various settings for the vehicle can be done through this system, navigation and reversing the image is also concentrated in this screen. Air conditioning and sound regulation or through ordinary physical buttons, the same operation is not complicated, seat heating is not integrated in the air-conditioning control area, but rather is designed to back of the transmission, the Acura RDX has only heated seats, does not have the ventilation function.
