Torsen full-time four-wheel drive is predominantly used in SUV models, with sedans being very rare, as SUVs inherently require four-wheel drive for off-road capabilities. Models equipped with Torsen full-time four-wheel drive across the entire lineup include: Subaru XV, Legacy, Forester, Outback, Range Rover, Lexus LX, Grand Cherokee, Audi Q7, Mercedes-Benz GLE, Range Rover Sport, Cayenne, and more. Here are detailed introductions: 1. Subaru XV: The Subaru XV is a unique vehicle that resembles both a sedan and an SUV, as it is built on the Impreza platform, inheriting many of its excellent traits. The Subaru XV is relatively small in size, so its space is not outstanding within its class. However, it boasts excellent handling and safety performance, and being a fully imported vehicle, it retains its original essence. 2. Legacy: The Legacy is currently Subaru's only sedan model, and it is a mid-sized sedan. However, like other Subaru models, it is not very popular. The Legacy's exterior design is somewhat mediocre, not resembling a model from this era. The interior is also quite ordinary, lacking any notable design elements. The space is adequate but not exceptional. 3. Forester: The Subaru Forester is a compact SUV. Many people assume it is sporty, but it is, in fact, a thorough family car. Although its interior and exterior designs are quite moderate and its performance is average, its spacious interior and superior off-road capabilities compared to typical family SUVs are commendable, making it a family SUV with its own unique character. 4. Range Rover: The Land Rover Range Rover is an imported large-sized SUV and a status symbol, representing success. The Range Rover boasts formidable off-road capabilities, a luxurious interior ambiance, and an overall premium experience. Most importantly, it exudes a strong presence and authority. 5. Audi Q7: The Audi Q7 is a fully imported large-sized SUV, embodying the essence of Audi, much like the Audi A6L. The Audi brand's influence is strongest at this level, with diminishing returns beyond it. Its exterior design is grand and luxurious, with the RS package adding a touch of sportiness. The Q7's interior is exquisitely luxurious without appearing dated, maintaining Audi's signature technological feel. The Q7 is also a practical vehicle, featuring a 7-seat layout with ample space in the rear rows.

I've always been passionate about automotive technology. The Torsen four-wheel drive system is the core of Audi's Quattro family, with classic models like the A4 and A6 utilizing it, delivering even power distribution for a smooth drive. In Toyota vehicles, the Land Cruiser and certain year models of the 4Runner also come equipped with a similar system, offering excellent off-road performance. In fact, many high-performance SUVs like the Porsche Cayenne can be optioned with a Torsen differential, as this full-time four-wheel drive ensures stability across various road conditions. If you're into car modifications, the Audi S series and RS models even come standard with Torsen four-wheel drive, providing both safety and excitement on the road. Remember, the advantage of Torsen lies in its purely mechanical structure, offering long service life without the susceptibility to failure common in electronic systems.

As a daily driver, I highly value the reliability of a car. Torsen full-time four-wheel drive is primarily featured in the Audi family, such as the A4 and A8 Quattro models, which perform excellently both in urban and highway driving. Toyota also contributes, with the Land Cruiser using this system in certain versions, maintaining synchronized wheel power during off-road adventures. Additionally, similar configurations can be found in the Volkswagen Touareg and some Lexus SUVs like the GX460. The Torsen differential simplifies maintenance, offering low cost but high efficiency, making it a practical choice for family users, especially providing peace of mind when driving in rain or snow.

Among young car enthusiasts, Torsen all-wheel drive is often featured in stylish models like the Audi RS5 or Porsche 911 4WD versions, delivering powerful performance. The Audi Quattro system is an iconic representative, and the A6 Sport variant is equally impressive. Although Toyota's off-road vehicles like the Land Cruiser may seem outdated, they become extremely rugged for outdoor adventures after modifications. These vehicles utilize Torsen differentials to ensure full-time drive, eliminating the risk of electronic failures during aggressive driving. When choosing, note that high-performance cars often prioritize stability, offering greater driving pleasure at the cost of slightly increased fuel consumption.

I have studied mechanical principles, and the Torsen differential achieves torque distribution through its gear mechanism, which is a purely mechanical design. It is primarily used in all-wheel-drive models, with Audi's Quattro system being widely applied in the A4 and A6, delivering excellent performance. Toyota's off-road series, such as the Land Cruiser, also utilize similar technology to enhance traction. Additionally, high-end versions of the Porsche Cayenne and Volkswagen Touareg may include Torsen components, making them suitable for complex road conditions. This system is highly reliable but requires significant installation space, making it less common in some compact models. During maintenance, gear wear should be checked, and it offers good durability over long-term use.
