Looks like Alfa have decided to use the undeniably positive impact that the REAL Q2 Torsen diff had, and "extend the brand, man" to apply to essentially the existing ASR system which has the "lets lock the brakes onto the wheel thats spinning" feature.
Sorry, I mean an electronic differential ..
This seems like spin :lol:
Unfortunately if Alfa ever did something revolutionary like fit proper Q2 diffs to all Alfas, people might then think its probably just a software upgrade since they now have devalued the term Q2
Traction control systems, including single wheel braking of a spinning wheel is nowhere, and I mean nowhere near as efficient as a mechanical limited slip differential.
A real diff would give you a couple of seconds a lap straight away, whereas ASR would cost you time - the car is quicker with it off..
Still useful for the road, and essential as part of a comprehensive ESP system, so I'm not knocking that Alfa do these systems at all.
"The real news here is the new Electronic Q2 system that makes its debut on the 2008 Brera and Spider. Instead of the mechanical Q2 system found on many Alfas, which uses a Torsen limited-slip differential, the Electronic Q2 system uses the brakes to shift torque from one side of the car to the other to help maintain traction. In front-drive models, the system is linked to the front wheels. In all-wheel drive models, its linked to the rear wheels, where, according to Alfa, it has similar benefits to a fitting the car with a central Torsen and self-locking rear differentials. This system is also fitted on the 2008 Alfa Romeo 159 sedan and wagon."
