They are only relatively unsafe when compared to 4WD or AWD cars and that's because these two can distribute the power generated across all 4 wheels. RWD cars can oversteer: lose grip at the rear when the car crosses it's limit and an average road driver will find it difficult to control the resulting slide.
What do I need? For rain and very light snow, 2WD will likely work fine, and for most vehicles, front-wheel drive is the preferred setup. (For performance cars, RWD is preferred, but AWD, if available, can increase traction. AWD is fine for most normal snow conditions or for light-duty, off-pavement excursions.
It's definitely possible, but you're basically going to need a GTR or a GTS-4 swap car for all the parts. You're likely better off just purchasing one of the AWD ones to begin with, or swapping an RB25DET into a GTS-T for more power and keeping it RWD. It would be a waste of time to rwd->awd a gtst.
Rear-Wheel vs.
It also improves traction since the weight of the engine and transmission is directly over the driven wheels. Rear-wheel drive generally offers better initial acceleration than front-wheel drive because weight is transferred to the rear of the car upon accelerating, which boosts traction.Better acceleration: An AWD or 4WD vehicle can accelerate better than a two-wheel-drive vehicle in inclement weather. "The advantage provided by AWD is mainly in the acceleration, as the traction needs will be equally distributed among all four tires," says Cyrille Roget, a spokesperson for Michelin North America.
Rear-wheel drive is often less ideal for driving in the snow. In most situations, RWD vehicles have less weight over the driven wheels than a FWD, AWD or 4WD vehicle, so they will have more difficulty accelerating on icy roads and a greater possibility of losing control of the rear of the vehicle.
Rear-Wheel Drive Pros (Advantages):
During dry conditions, rear-wheel drive improves handling due to “load transfer” in acceleration and more even weight distribution. Rear-wheel drive tends to have less costly maintenance since there aren't as many parts packed into a small space.Another important example of the increased level of safety of an All-Wheel Drive car compared to a Rear-Wheel Drive car is when cornering under drive power. Meaning that the best AWD car will lose sideways grip at much higher cornering forces than the best RWD car.
One of the main advantages that front-wheel-drive cars have over RWD vehicles is their improved traction, which results from their weight distribution. In addition to better traction, FWD cars typically have more room than vehicles with rear-wheel-drive.
For rain and very light snow, 2WD will likely work fine, and for most vehicles, front-wheel drive is the preferred setup. (For performance cars, RWD is preferred, but AWD, if available, can increase traction. AWD is fine for most normal snow conditions or for light-duty, off-pavement excursions.
In general, cars equipped with 2-wheel drive get better gas mileage than models that use all-wheel drive or 4-wheel drive. There's a reason: AWD or 4WD cars have to send power to each of the vehicle's wheels, which requires extra energy. AWD cars also offer worse gas mileage than 2WD rivals because they're heavier.
4WD can also be turned off in order to preserve fuel. AWD offers you advanced traction, grip, and control in a variety of road conditions, so it's your best option if you're looking for increased stability and handling. Because AWD never turns off, it does greatly reduce your fuel economy.
The short answer is yes, an all-wheel drive vehicle is more expensive to maintain for one simple reason: an AWD vehicle has more components. According to EPA estimates, the AWD Rogue will cost around $150 more a year in fuel, if driving 15,000 miles a year.
AWD cars also offer worse gas mileage than 2WD rivals because they're heavier. AWD and 4WD drive systems can add hundreds of pounds to a car's curb weight, and that extra bulk can have a big impact on fuel economy.
All-wheel drive can help you get started on icy roads; however, it doesn't improve traction, which is what you really need. While front- or rear-wheel drive cars send all their power either to the (drumroll please) front or rear wheels, all-wheel-drive cars can send power to the wheels that have the most traction.
For rain and very light snow, 2WD will likely work fine, and for most vehicles, front-wheel drive is the preferred setup. (For performance cars, RWD is preferred, but AWD, if available, can increase traction. AWD is fine for most normal snow conditions or for light-duty, off-pavement excursions.
Best AWD Systems
- Audi. Audi's Quattro system was derived from the Volkswagen Group's early development of four-wheel drive systems during the Second World War.
- Subaru. Subaru claims that it has taken nearly 40 years to perfect, but they seem to have perfected their Symmetrical AWD system.
- Acura.
- Toyota.
- Porsche.
Front-wheel drive cars are generally more affordable than all-wheel drive cars. This is due to less parts, and a perceived lack of utility. FWD is cheaper to buy, and cheaper to operate. Snow tires are a cheaper option than AWD.
Electrified all-wheel drive
| AWD pros | AWD cons |

| Provides increased grip and control under all road conditions | Reduces fuel economy |
| Gives sportier handling and traction to a broader range of cars | Increases the weight and complexity of vehicles |
| Works all the time | Not as good in extreme off-road conditions |
Weight Problem
The biggest problem with rear-drive cars in snowy weather is one of weight. Instead, rear-wheel-drive vehicles typically have an empty trunk or cargo area directly over the rear wheels. The drive wheels struggle for traction because they don't have as much weight on top of them.Rear Wheel Drive
There are two main advantages to owning a RWD car. As anyone who has owned one will tell you, RWD cars are at their weakest in poor weather rain and snow. Even with modern traction control, a RWD car is more prone to loss of traction on slick roads.On the practical side, some luxury vehicles are performers too, and the rwd/awd layouts allow them to make better use of their power. Having a RWD car means the front wheels can concentrate on steering and the back wheels can propel the car. In a FWD car the front wheels do everything, steering braking, propulsion.
Quora User, Automotive aficionado and hoarder of esoteric information. For the past couple decades, RWD police cars were the preference for police offers and fleet managers because of their size, trunk size, acceleration and cost savings. RWD cars are historically less to maintain than FWD, and much less than AWD.
The upside: FWD cars can actually be pretty tenacious in the snow because the weight of the engine/transaxle is sitting right on top of the drive wheels. FWD is vastly better in the snow than a rear-wheel-drive car. This is why most race cars and also high-performance cars are rear-wheel-drive.
