How fast can you go in 4 wheel drive low?
When to use Low: To maximize both power and traction, you can rely on low-range 4×4 for crawling over rocks, fording creeks, plowing through deep sand, or negotiating steep off-road trails. At this setting, the wheels turn more slowly than on High, so use Low only at speeds of 40 MPH or less.
4L is the low-range four-wheel drive setting and can help you maneuver out of tricky situations. If you're using this setting, be sure that you keep your speed under 10 mph, which is because the vehicle is applying more torque for a better grip.
4lo should really not exceed 10-15mph max. 4hi should be between 50-55mph.
Low range is generally for slow-going; don't use it for high-speed driving on any surface. In fact, don't use low range at speeds faster than 60km/h for long periods because that may result in serious damage to your vehicle.
How fast can you go in 4L? 4L is not designed for speed. It is a low gear ratio designed for maximum torque and power. Therefore, If you are using this setting, be sure that you keep your speed under 10 mph.

4WD Low. Edmunds says 4WD low range is for off-roading conditions, like deep sand, where you need serious traction. Unlike 4WD high, adds Motor Authority, the low setting turns the wheels slowly but gives you more torque on less forgiving terrain.
If you are moving at speeds greater than 25mph and need superior traction, then 4WD high will be the way to go — such as cruising to the ski slopes on the interstate when the first snowflakes begin to fall. When to use 4 Low? When speed doesn't matter, but brute-force does, then you'll want 4 low.
Just slow down. “But is there a reason you'd want to go 70 in the snow??” That's 20 MPH slower than 90 on dry pavement. You should NEVER drive a vehicle in part time 4wd at highway speeds, whether it's dry pavement or slippery conditions.
Engage your 4WD every few months to keep it in working order. Don't use 4WD on dry pavement. Avoid engaging 4WD when driving on flat, dry road surfaces. Your fuel efficiency will take a hit, along with your drivetrain.
How low is too low to drive a car?
As a driver, maintaining the correct tire pressure is always a good idea. Keep it between 32 to 35 PSI. Any lower than 20 PSI, though, and you've got a flat tire.
In short, while you can absolutely use four-wheel drive in inclement weather for highway driving, you should not use it in good weather conditions. In addition, when you do need to engage four-wheel drive on highways, make sure it's 4H setting.
The fastest 4x4 is the Hennessey VelociRaptor 6x6. It has a top speed of 150 mph and can go from 0 to 60 mph in 4.9 seco.
You can use 4H when you are driving on the highway in snowy conditions, or when driving on a smoothly paved dirt road. It's smart to keep speeds under 55 mph if you have shifted into 4H. 4L is designed to give you more torque in those super difficult driving conditions.
Purely speaking, 4×4 cars have engines that power all 4 wheels. In most cars, as well as crossover SUVs, the 4×4 drivetrain systems are all-wheel drive (AWD), and not four-wheel drive (4WD) as commonly found in trucks and off-road SUVs.
4x4 high when you're on a smooth surface with low traction, like a snowy roadway or muddy back road. 4 Low when you're on steep slippery spots or rock crawling, or towing something on slippery surfaces. Being in 4 low allows more torque with less throttle so you can have more control.
Please note that you shouldn't use 4-low for high-speed driving, especially at speeds of more than 35 mph. Doing so could result in damage to your vehicle and costly transmission replacements. Note also that not all SUVs feature a 4-low option. Therefore, choose your make and model carefully if you want this feature.
High Range 4wd, or 4-high, allows you to drive full speed, if needed. The high range 4wd ratios are the same gear ratios that the vehicle has in 2wd. The best time to use 4 high is when additional traction is needed on terrain that is not very steep. 4 high is good to use on snow, ice, and muddy roads.
In most vehicles capable of 4WD, they are either constant 4WD (“real” 4WDs) or part-time 4WD. Those which are part-time 4WD normally would have to be stopped to then change between 2WD and 4WD. On older vehicles, hubs would have to be locked at the same time.
Four-wheel drive vehicles are more expensive than two-wheel drive. Four-wheel drive vehicles consume more fuel because four-wheel drive systems use more energy.
Can you use 4h at low speeds?
Unlike 4Lo, 4 Hi should be used when you're dealing with slippery conditions on otherwise good roads, such as ice or rain. 4Hi should never be used below 15 mph. As a result, you should not use 4Hi to try to get unstuck.
Yes, 4-wheel drive improves handling and traction in slippery road conditions including mud, ice, snow, and rain. The 4wd will feel more sure-footed and secure in slippery, oily conditions because all 4 wheels are propelling the vehicle forward.
If you live in an area with heavy snowfall, the best option will be AWD or 4WD coupled with good winter tires. City/Suburban driving with moderate snow and ice – FWD or RWD with winter tires will suffice.
Four-wheel drive vehicles generally have three settings: 2H, 4L, and 4H. 2H is ideal for normal, everyday driving. Use 2H for dry, flat, paved roads. 4L is best suited for a time when you need maximum traction and power.
When you select 4Lo, you're lowering the gear ratio to multiply the amount of torque sent to the driven wheels. On the other hand, 4Hi is for when you want the security of all four wheels being powered, but you're driving at higher speeds.
