Car and Driver recently tested a 2016 BMW 328i xDrive. It has good performance numbers (posted here earlier in the ATS4 2.0T post). It seems like a good little car.. until you get to the price. I'm more dumbfounded by the proximity of price to the +BMW M3 than I am by the price alone. $59k?? One doesn't have to go far to find a much better deal. An +Audi S4 starts almost $10k under it. I just can't wrap my head around choosing this over an S4. This isn't expensive compared to a mainstream car with comparable performance/options. Both this and the S4 are German, both are AWD, and both are well established luxury brands. I personally put a lot of weight on a RWD-based chassis but this automatic 328i xDrive isn’t exactly a purist’s choice and at 3,700 lbs, it isn’t a featherweight. I would imagine discounts on it would be huge to lure someone away from an S4. That, or you have to be an absolute die-hard BMW fan to buy one.
A few weeks ago, I made a post explaining mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky
