Other rear-weighted all-wheel drive systems
Seen on: Lexus All-Wheel Drive, Infiniti Intelligent AWD, Dodge Charger R/T AWD, Mercedes-Benz 4Matic, Porsche Traction Management
How they work: These all-wheel-drive systems are found on vehicles based on a rear-wheel-drive chassis and, consequently, tend to be more performance oriented. The default power split varies between manufacturers. Lexus starts with a 30/70 front-to-rear split for its IS, GS, and LS sedans. Meanwhile, Infiniti's Intelligent AWD has a resting state of 100 percent rear axle power with the front wheels only getting torque on-demand. Some Mercedes-Benz 4Matics can be locked into a RWD mode or a 4WD mode with a 35/65 front-to-rear axle torque split. What all of these systems share is that they're limited to a max 50/50 split, which means the front axle is never more powerful than the rear, maintaining the rear-wheel-drive pedigree.
Advantages: Usually more performance oriented
