The difference between Mitsubishi's Super Select 4WD system and full-time 4WD system lies in their driving mechanisms. The Super Select 4WD system allows switching between 2H and 4H modes at speeds below 100 km/h, while the full-time 4WD system keeps all wheels independently moving at all times during driving. Below are some relevant introductions about 4WD systems: 1. 4WD refers to a vehicle's four wheels moving independently during driving, which is a transmission method with higher cornering limits on roads. It can distribute optimal driving force to each wheel when the vehicle is turning at high speeds. 2. 4WD systems are categorized into part-time 4WD, on-demand 4WD, and full-time 4WD. Part-time 4WD is a system where the driver can manually choose between two-wheel drive and four-wheel drive, achieving the purpose of 2WD or 4WD by engaging or disengaging the transfer case according to driving needs.

The biggest difference between Mitsubishi's Super Select 4WD (like the SS4-II system) and full-time 4WD lies in the flexibility of mode selection. Super Select 4WD offers multiple gear shifts: for example, 2H is a pure rear-wheel-drive mode, which saves a lot of fuel when driving on regular roads, with fuel consumption similar to that of a regular car; 4H is an all-wheel-drive mode with slight speed differences between the wheels, providing more stability but without locking the center differential; 4HLC locks the center differential, making it suitable for high-speed off-roading. Full-time 4WD, on the other hand, keeps all wheels constantly driving, with the center differential always engaged, making it safer on slippery roads but always consuming more fuel than rear-wheel drive. When driving a Pajero, I appreciate the flexibility of Super Select—using rear-wheel drive for fuel efficiency in daily driving, switching to 4H in the rain to prevent slipping, and locking up for off-road challenges on dirt roads. Full-time 4WD can't do this; it always keeps all wheels driving, resulting in higher fuel consumption in urban areas. It's more suited for all-weather conditions requiring constant all-wheel drive, like driving an Q series. The clever design of Super Select lies in combining the benefits of part-time and full-time 4WD, offering lightweight driving without compromising performance—a smart evolution worth praising.

I've driven vehicles equipped with Super Select 4WD, and what impressed me most was the practicality of mode switching. Full-time 4WD provides stable driving but always struggles with fuel consumption control, especially during daily commutes where it feels wasteful. Super Select 4WD allows manual adjustments: switching to 2H rear-wheel drive on highways shows noticeable fuel savings; when encountering rainy or slippery roads, engaging 4H mode instantly boosts wheel traction and safety; for muddy terrain or hill climbs, activating 4HLC or 4LLC with center differential lock enhances climbing capability. Full-time 4WD operates continuously without segmentation, automatically distributing torque – convenient for daily use but lacking precision in off-road control. Driving this system feels like the vehicle understands your commands and adapts on demand: fuel-efficient like a regular SUV when needed, transforming into an off-road beast when facing hazards. While full-time 4WD is versatile, it often feels slightly vague, whereas Super Select's logic is straightforward and practical – once experienced, its adaptability to variable environments becomes clear. Mitsubishi owners sharing such experiences frequently highlight this versatile and cost-saving advantage, which particularly appeals to family users.

Simply put, Super Select 4WD is like a magic glove that can switch modes, while full-time 4WD is a pair of waterproof gloves you wear all day. Super Select allows the vehicle to adapt differently on highways, wet roads, or off-road: normally you drive in rear-wheel drive for fuel efficiency and ease, but when it suddenly rains or you hit dirt roads, it switches to full-time 4WD mode for better traction without locking the center differential, and you can lock the center differential anytime for more off-road power. Full-time 4WD, on the other hand, always drives all wheels, constantly protecting you but with higher fuel consumption and a heavier system. Once you've driven it, you'll understand—Mitsubishi's design is and flexible. The difference lies in Super Select's ability to choose part-time drive, while full-time 4WD always requires all-wheel drive. If you frequently go off-road or want better fuel efficiency, Super Select is more suited for an everyday adventure life.

From an economic perspective, the Super Select 4WD system is generally more cost-effective and fuel-efficient than full-time 4WD. When driving a Pajero, using 2H mode on highways yields fuel consumption close to that of a two-wheel-drive vehicle, typically around 8-9 liters per 100km. Switching to 4H mode results in slightly lower fuel consumption compared to full-time 4WD vehicles, around 10 liters per 100km. Full-time 4WD systems, like those in vehicles, always engage all wheels, leading to consistently higher fuel consumption by 1-2 liters and higher maintenance costs due to their complex electronic systems, which are more prone to failures. The Super Select system's simplified and durable design makes repairs cheaper, and Mitsubishi's maintenance manuals often highlight its high reliability. For those on a tight budget, I recommend opting for a Super Select 4WD vehicle, as it offers a more rational cost balance between city driving and off-road use.

From a practical application perspective, Mitsubishi's Super Select 4WD evolved from the old part-time system by incorporating the advantages of full-time 4WD, achieving its full potential in the Pajero: you can switch modes anytime, like using rear-wheel drive for daily fuel efficiency or full-time 4WD for enhanced off-road capability. Full-time 4WD vehicles like Audi's Quattro constantly drive all wheels, offering a stable but less versatile system. When tackling mountainous dirt roads, Super Select 4LLC with a locked center differential and torque amplification excels at climbing steep slopes, whereas full-time 4WD typically relies on electronic speed limiting and struggles in extreme conditions. The key difference lies in Mitsubishi's system being designed for versatile terrain with flexible switching, while full-time 4WD offers balanced adaptability but sacrifices peak performance. Choosing the right system based on your driving scenarios is crucial—Super Select is ideal for both adventure and daily use.
