Yes the BRZ isn't AWD but that doesn't mean we can't be proud to own a Subaru.
Who knows maybe the BRZ will one day be all wheel drive.
Who knows maybe the BRZ will one day be all wheel drive.
This year marks the 40th anniversary of the debut of the Subaru’s symmetrical All-Wheel Drive (AWD) vehicles.
During the past 40 years, Subaru has continued to be a pioneer of passenger AWD vehicles, according to Subaru Canada. In fact, the total production of Subaru AWD vehicles has reached 11,782,812 units (as of January 31, 2012). This is approximately 55.7 per cent of total vehicle sales for Subaru.
Subaru’s AWD system provides traction by distributing engine torque to all four wheels in a balanced manner. With the combination of Subaru symmetrical full-time AWD and Subaru’s horizontally opposed SUBARU BOXER engine, the whole powertrain is mounted with side-to-side symmetry and the transmission sits back from the front axle within the wheelbase. This layout optimizes the longitudinal-transverse weight balance, bringing stable traction on a multitude of road surfaces and driving conditions.
Through continuous research and development over the past 40 years, Subaru has refined its AWD technologies from a basic technology capable of rough road driveability to the advanced engineering available today, added the vehicle maker.

Back in 1972 in Japan, Fuji Heavy Industries and its Subaru car brand launched their first passenger vehicle equipped with all-wheel drive. Little did they know that four decades later, the system employed by the Leone Estate Van 4WD would largely define the brand and the majority of its models.
All-wheel drive back then was a rudimentary technology. But even so, it was highly effective in providing much needed traction in a variety of environments and climates. Together with Subaru’s now-iconic flat-type engines, all-wheel drive dramatically improved grip in performance situations as well.
Fast forward 40 years and some 11.8 million (11,782,812 units as of January 31,2012, to be precise) all-wheel drive-equipped Subarus have rolled off its many production lines around the globe. Naturally, the drivetrain has evolved over the years and is now called Symmetrical All-Wheel Drive.
Nearly every vehicle (minus some JDM-spec kei-cars, trucks, and the rear-wheel drive BRZ) employs one of four basic variations of S-AWD. Throughout the decades, we’ve learned to love them all, and for that, we say Happy Birthday to Subaru’s effective all-wheel drive.
Here’s a brief breakdown of Subaru’s most current AWD setups:
- VTD-AWD or Variable Torque Distribution All-Wheel Drive
Meant for “sporty” vehicles, this setup utilizes a center differential that’s married to an electronically-controlled hydraulic multi-clutch limited-slip differential. In normal conditions, torque is split 45/55-percent front/rear, but can vary to 50/50.
- Active Torque Split All-Wheel Drive
Meant for models that emphasis fuel economy rather than performance, this front-wheel drive biased setup electronically controls a Multi-Plate Transfer case (MP-T) to vary torque in real time. In normal conditions, torque is split 60/40.
- Viscous Center Differential All-Wheel Drive
Meant for models equipped with manual gearboxes, the setup employs a torque-sensitive bevel gear-type center differential and viscous limited-slip differential. Normally, torque gets distributed at an even 50/50 split, but can react quickly to changing grip levels and manage slip accordingly.
- Multi-Mode Driver’s Control Center Differential (DCCD)
Meant for serious performance rides (i.e. STI models), the configuration combines a mechanical torque-sensing mechanical limited-slip differential and an electronically-controlled limited-slip differential. Mixing the two allows for near instantaneous torque and power distribution (thanks to the mechanical LSD) and a wider range of predictable behavior (thanks to the electronic LSD and its pre-programmed Gravel, Tarmac, and Snow modes). Normal driving means torque is distributed at a rear-biased 41/59 level.
Subaru will have a celebratory display at next month’s Geneva Motor Show in Switzerland, so stay tuned for more S-AWD goodness.

If you live in a cold climate and your all-wheel-drive (AWD) car provides you with good traction during the winter months -- or you live in some other type of place and it gives you great grip all year around -- you should tip your hat to Subaru, which introduced its first AWD vehicle 40 years ago.
While the Japanese automaker wasn’t the first to include it on cars, the brand has become synonymous with AWD since it’s been included on over half of the 12 million vehicles Subaru’s has sold worldwide since the debut of the Subaru Leone Estate Van 4WD (pictured at left) in Japan in 1972.
AWD has helped drivers keep their cars rubber-side down over the years by distributing and balancing engine power to all four wheels. Subaru’s combining of Symmetrical AWD (S-AWD) and a horizontally opposed “boxer” engine optimizes weight balance to provide stable traction on various road surfaces and in a wide range of driving conditions. The technology and the brand have also become favorites of “boy racers” and WRC fans worldwide due to stability at high speeds and crisps cornering and responsiveness (that, and because Subaru vehicles typically offer good value).
Subaru’s parent company, Fuji Heavy Industries, has refined AWD over 40 years, taking it from a technology that was initially designed to help smooth rough-road driving to now being the poster vehicle for regions like New England and the Pacific Northwest, where stickiness in rain, snow and other mucky conditions is essential. The latest evolution in Subaru AWD technology is a four-wheel traction-management system that the automaker uses in the development of front-wheel drive and rear-wheel-drive vehicles. The latter has been put to good use in Subaru’s first rear-wheel-drive sports coupe, the BRZ.
So Happy Birthday Subaru Leone Estate Van 4WD, and thanks for all you've done.
