Im considering this vehicle, coming from an Audi quattro background.

It says this is a FWD car and when wheel slippage is detected it splits the distribution to 50/50 FWD/RWD bias.

Im concerned about deep winter driving conditions and general performance in our Canadian winters.

Any thoughts on how or is this a great winter driving car?

Thanks in advance!

4Matic. 4motion is vw.

The awd works great in winter, the system transfers up to 50% when needed to the rear wheels so it offers great economy and all weather driving capability. Where in Canada are you from?

Fully variable 4MATIC all-wheel drive
• Up to 25% lighter than all-wheel-drive systems offered by competitors
• A two-piece propeller shaft transfers the power from the engine to the
rear axle
• An electro-hydraulically controlled multi-disc clutch is integrated with
the rear axle differential (AMG tuned for GLA 45 AMG 4MATIC)
• The multi-disc clutch immediately detects slip at the front axle and
channels the engine torque to the rear wheels as necessary - All this
takes place virtually without the driver noticing
• In normal driving, the 4MATIC system uses front-wheel drive in the
interests of optimum efficiency
• During spirited driving, the fully variable 4MATIC all-wheel drive splits
the torque between front and rear axle up to a ratio of 50:50 front to
rear
• 4MATIC adjusted according to selected setting of 3-stage ESP
(GLA 45 AMG 4MATIC only)
