Automotive history is adept at repetition itself and whereas just about all technological trends have resurfaced repeatedly over the last one hundred years, there square measure important milestones for every ground-breaking innovation.

The same is true for drivetrains and driven wheels.

Notwithstanding the odd exception, rear-wheel drive was the staple for the bulk of rider and business vehicles as so much back because of the birth of the automobile as we all know it these days.

In the late Nineteen Fifties and once a variety of niche models, it had been the mini that established the now-commonplace transversal engine, front-wheel drive layout as a genuinely sensible proposition.

Then, in 1980, Audi’s Quattro was the pioneer that brought simple machine drive from the cross-country arena into the globe of on-road superior cars.

These 3 radically totally different drivetrain approaches have currently proliferated into the model ranges of just about all brands, providing a large number of alternatives for the patron.

Here square measure the key variations to think about once selecting what’s right for you.



Many regard rear-wheel drive because of the purist’s answer and therefore the sole layout for optimum driving enjoyment.

The theory goes that by driving the rear wheels, the front wheels square measure allowed to urge on with steering, and a majority of the braking, for complete and balanced driving manners.

Generally speaking, driving the rear wheels additionally promotes an additional inherent tendency for oversteer on the limit, that is taken into account additional fun and manageable within the right hands than the understeer usually related to front-drivers.

The engine during a rear-wheel drive is usually headed lengthways (if placed at the front), which permits the installation of a bigger engine provided the engine bay is long enough to accommodate it.


The natural tendency to oversteer may be unsafe for inexperienced drivers (although it's up to the driving force to take care of the management of any vehicle given the circumstances), however trendy electronic stability systems square measure effective at keeping cars on the straight and slender.

Sending power from a front-mounted engine to the rear wheels needs a prop shaft and rear differential, that take up the area and add additional weight. Most rear-drives have a ‘transmission tunnel’ that robs some cabin space on the center of the automobile.

By confining the large engine, gearbox, driveshafts, and steering to the side of the automobile, the remainder of the vehicle’s area is freed up for occupants and baggage.

The overall vehicle package may be created smaller and just about all vehicles within the compact section use a front-engine, front-wheel-drive layout.


For superior applications, obtaining power right down to the road through the front wheels causes additional issues than a rear-driven automobile, and wheelspin is additionally possible, notably on slippery surfaces like mud and ice.

Another typical front-drive attribute in additional powerful vehicles is a control known as ‘torque steer that is once the automobile pulls to 1 aspect with significant throttle application. several makers have tried to counter the impact with a variety of solutions, and with varying levels of success.

Front-drive cars use a tool known as a ‘constant velocity joint or CV joint that permits the driveshaft to show with the steering wheels however the restricted adeptness of the CV joint additionally contains a limitation on most steering angle and turning circle.

With the complete drivetrain over the front shaft, front-wheel drives have a natural tendency towards understeer, which is exacerbated with the applying of an excessive amount of power, even as excessive power encourages oversteer in rear-drives.

It is additionally tougher for engineers to distribute the vehicle weight equally over the axles, which affects handling.



In a word – traction. With all four wheels causation torsion to the surface, all-paw cars provide a security and performance advantage compared with two-wheeled drive cars, notably in adverse climates and on loose surfaces.Acceleration from a standing begin is mostly quicker in high-powered vehicles with the utmost power of the engine shared between a bigger tire contact patch.

The traction advantage additionally makes simple machine drive cars additional appropriate for towing larger masses or on slippery surfaces wherever the additional ground-clearance of associate degree SUV isn't necessary.


With an additional shaft to drive, the extra differential and try of half-shafts makes a simple machine drive system heavier than two-wheeled drive systems and this may have a control on fuel consumption and presumably handling.

There square measure systems that disconnect one try of wheels once they aren't needed that cutbacks motility losses however they can't reduce the consumption caused by carrying around further weight.
The extra differential and driveshafts may increase the number of service things that need attention once sure maintenance works.


All-wheel-drive systems don't increase the ‘grip’ of a tire. simple machine drives have a traction advantage over 2 wheel drives as a result of all four tires will contribute however, ultimately, the grip of a vehicle is settled by the performance of the rubber on the road.

This notably applies to throughout cornering wherever the speed of the automobile is ruled, not by the driven wheels, however additional by the weight-distribution of the automobile, center of gravity, tire performance, and mechanical system.

There square measure exceptions to any or all of the examples given, and therefore the on top of is meant solely as a general guide to assist you to begin puzzling over that layout most closely fits your needs, however as perpetually, the simplest approach is to urge out there and begin to take a look at driving.
