Why do you say you don’t follow Highlander when going uphill, and you don’t steal Mazda when stealing a car?

"Don't follow the Highlander when going uphill, and don't steal a Mazda when stealing a car." ----------The first half of this sentence is actually a more appropriate joke. Let’s talk about Highlander’s problem first. Uphill is not the same as Highlander. It originated from the “Hill Climbing Gate” incident in 2013.

The general story of the incident was that a car owner drove a 2009 2.7-displacement Highlander and skidded on a 30° high slope.

This issue caused an uproar at the time, but in fact, many friends did not understand why Highlander was not able to escape difficulties at all -------- Even today, on this issue Next, some respondents still said that "the last Highlander four-wheel drive did not have this problem"...

The 2009 Highlander two-wheel drive version cannot go to Tangtou. Slopes are an established fact -------Front-wheel drive vehicles with their heavy weight and high ground clearance have more difficulty going uphill than two-wheel drive vehicles. It is understandable that the front wheels have small friction and are prone to slipping, but here comes the problem. , if it were that era (even models before 2012), even if it is equipped with four-wheel drive, the Highlander will still skid ------ This is not to say that its car is not good, but that the Highlander uses it. The full-time four-wheel drive is just a thing.

As shown in the picture, the Highlander's full-time four-wheel drive is equipped with an open differential, which allows it to distribute power well when driving on the road, greatly improving road stability--- ----But when it comes to getting out of trouble, sorry, the open differential has no ability to get out of trouble.

It’s very simple. The laws of physics tell us that all energy will flow away from the place of least resistance. Therefore, if a full-time four-wheel drive with an open differential without a locking function has wheel slippage, all the power will be lost from the slippage - the result is that the suspended wheels spin and the wheels on the ground remain motionless. .... Of course, before 2012, it was very pertinent for us to say "Don't follow the Highlander when going uphill", but since 2015, the Highlander's four-wheel drive has been upgraded from "so-called full-time four-wheel drive" to a multi-plate clutch. After timely four-wheel drive, its ability to get out of trouble has been greatly improved. Today in 2019, it would be inappropriate for us to say this again.

Next, let’s talk about “stealing a car but not a Mazda”. As mentioned before, the first half of the sentence (not following a Highlander when going uphill) is not completely targeted, but the second half of the sentence is about stealing a car but not a Mazda. Mazda is bullshit.

The reason for this problem is that Mazda has a loud startup noise, but in fact, the reason why Mazda is slightly noisier is because of the SKYACTIV-G engine (SKYACTIV-G engine), which requires the engine to be in a cold start state, and when the engine is cold, The startup noise is not small - this is just increasing the engine speed to fully warm up and lubricate, and it is not considered a problem at all. If we insist on stealing cars but not Mazda because of this problem, then why not say stealing cars but not Veyron and Koenigsegg? Or why don't you say you stole the car but not the three-cylinder engine?

In short, Chinese people particularly like to "label" and always feel that everything is black and white. This is obviously wrong. Cars are just tools, not art--not to mention that they are not even works of art. Perfect, everyone chooses cars simply because they can accept their shortcomings and their advantages are urgent needs.

Comments and Analysis

We will not delve into the black jokes. In addition to more public opinion hype, we will analyze it rationally. Going uphill is not the same as the Highlander. I am talking about the old two-wheel-drive Highlander with the 2.7L naturally aspirated engine in the 13 models. The two-wheel-drive car plus the front and rear body ratios are different in weight. The long wheelbase causes the rear wheels to exert more force, and the front wheels have more force. The wheels are slipping without applying force, idling and unable to go up the slope. It wouldn't be so embarrassing if it were switched to four-wheel drive. Therefore, it is recommended that enthusiasts who often go off-road can buy a four-wheel drive version of the SUV. Stealing a car but not a Mazda is because the Mazda 3 makes too much noise when started cold. The Chuangchi Blue Sky gasoline direct injection engine equipped with Ma 3 uses a special 4-2-1 exhaust structure, but there is a problem with this exhaust manifold structure, that is, the three-way catalysis is too far away from the engine. It takes a long time for the three-way catalytic converter to reach operating temperature, so the three-way catalytic converter is heated up by delaying ignition during cold start. This means that the gasoline is not completely burned in the cylinder, but part of the gasoline is burned in the exhaust pipe. , so the noise will be relatively loud, which is also a small negative impact of the ultra-high compression ratio. However, this sound will disappear after the car is warmed up. I can only slowly get used to it and accept it.
