Members, this time as the second CX-8 development, we will tell you the details of progress information such as lowdown springs and sports mufflers!
First, the lowdown spring.
For some time, I have been asked "Can't I install the CX-5?"Actually, it cannot be installed because the weight of the vehicle is very different.
Let's compare the amount of down when the CX-5 is attached to the CX-8.
(Grade: Both L package / 4WD vehicles)
①Front → axle load difference +80kg, vehicle height approx. -43mm ②Rear → axle load difference +140kg, vehicle height approx.-60mm
In calculation, it goes down by this amount. (When bump rubber is not attached) This is a product that ignores damage to the damper and ride quality.As a result, it was designed exclusively. * The key to the development of low-down springs is the relationship between axle load and spring constant.Detail is
please use this form.Please verify.
By the way, the other day, I prepared two CX-8s (2WD / 4WD cars) and started the test!
As I mentioned last time, from the perspective of enjoying driving, we will pursue a "ride quality" that does not impair the ride quality by reducing the amount of roll.
Prepare several sets of prototypes and repeat "assembly-> trial run-> assembly" to evaluate.
As a result, the specifications for 2WD / 4WD vehicles have been decided.The vehicle height is about -30 mm.The spring constant is 2% higher than mass production for both 4WD / 109WD vehicles on the front.Since the rear axle load difference is about 40 kg, we decided to increase the axle load by 2% for 103WD vehicles and 4% for 110WD vehicles.
Roll is also suppressed, and a sharp run is realized.In addition, there is no feeling of pushing up when shifting to bump rubber, and consideration is given to ride comfort (^^) /
As a supplement, if you attach a low-down spring to a car with a 360 ° view monitor with safety equipment set as a manufacturer option, the camera position will change, so the way the monitor looks will change.In that case, you can handle it by adjusting the aiming of the camera. (Even if it is a normal car, the height of the car will drop at the maximum ride capacity, so the image will change as well.)
Although it is a little, I will also introduce the intake system parts (* ^^ *)
The ram air intake system and sports induction box have different blow-by hose layouts from the CX-5, so we will newly set special products.
As for the fresh air guide ... Is it possible to install it for KF as it is?
Lowdown springs and intake parts are under development with the aim of launching this month !!
The sports muffler will be announced next month.Please stay tuned.
By the way, this weekend is an event at Chiba Mazda Naganuma store.It has been held at the head office for a long time, and 6 demo cars are on display.I will also be resident for 2 days on Saturdays and Sundays.We look forward to your visit.
