How fast can cars go in reverse

Every gear in the transmission has both a drive gear and a driven gear or, technically speaking, one gear on the input shaft and another on the output shaft, which mesh together. To use their example, the EVO 7 has a first gear with 14 teeth on the driving gear and 41 teeth on the driven gear.

This means that for every 2. Ever thought: how fast can a car speed in reverse gear? Many action movies with car chase scenes have shown us how fast a car can go in reverse gear. The popular "fast and furious" sequel had Paul Walker Bryan O'Connor reversing a Mitsubishi Lancer Evo on the highway at top speed just to show off his driving skills to his female front seat partner.

The question is, is it real? Well, I am sorry to break to you that it's all lies. Cars have a dedicated gear to reverse , and this gear is just one.

If you know the tips on how to reverse safely , then you would know why it is unsafe to reverse at high speeds. Most people wrongly put their head out of the car while reversing. Car manufacturers know that driving in reverse activates a lot of blind spots and it is best to drive slowly just so that the driver can manage all the risks involved. Most car rear don't slope down like the front, so it's always bad outward visibility when reversing. Humans don't have eyes at the back of the head, so all three mirrors must be used simultaneously and this reduces the precision of movement.

It is very difficult to drive around bends in reverse gear even at low speeds because of weight distribution on the car and also the fact that drivers can't have an accurate judgment of the bend. Though, there are some electric cars that have been made to reverse at high speeds after some modifications. The video below ill help you understand more. Josh Max. Pity poor reverse; modern cars typically have 4, 5, 6 or even 7 forward gears, but reverse gets a measly one.

So I was pleased to accept the challenge of discovering how fast a ride can go backwards, and decided to use a Audi S5 loaned to me as my guinea pig. I wasn't arrogant enough to think my little test was going to provide the definitive answer, though, so first I consulted Mike Allen, senior editor at Popular Mechanics, who builds, works on and races cars and who was dubious about getting any sort of speed going in reverse. Couple that with the fact you're driving while looking over your shoulder, and top speed runs in reverse usually terminate in a spectacular spinout.

It's very difficult to go in a straight line while driving backwards. All streets but one had been cordoned off by authorities to provide space for a bike race, the competition had just finished and the street was completely devoid of people, cars and anyone but the police. The only way for me to get to an artery leading to a street where I could pick up a highway out of town was to back up one-way, which I was given permission to do by a friendly officer.

I reported my results to Rick Roso, a year racer and media liaison for Lime Rock Park , who said, "Usually reverse gears are based on what first gear is, so you'll be RPM limited. I'm pretty sure you can go faster than 12, but you need the gear and the skill and the room.

And do you really want to take your own car to engine redline? We asked General Motors if they kept top speed numbers on their reverse gears. Not surprisingly, they peered down at us over their reading glasses like we had asked to swing the family cat around the living room.

Each vehicle application regarding reverse gear is somewhat unique and engineered accordingly. Specifically, gear ratios for gradeability — so you can back up a steep incline — is something we design for.
