Ok, an update to my earlier post:
Quote:
Not much of a change but better than nothing and I guess in the grand scheme of things, that does alter the ride a bit... Quote:
The secret to the exhaust manifold, which sits in the valley between the two cylinder banks, is a convoluted plumbing system. Exhaust gas from each cylinder is routed to the dual twin-scroll turbochargers; each scroll is fed by a distinct pair of cylinders. The pairs are matched in such a way that the two cylinders fire a full crank rotation apart from each other. (In a four-stroke engine, every cylinder fires every two rotations.) This facilitates steady pulses of exhaust gases to spin the turbo, whereas a more conventional exhaust manifold will form waves of pressure. The M solution, while expensive, results in better engine response and less turbo lag. The torque peak, which runs flat from 1500 to 5650 rpm, backs up this claim. At max boost, the Garrett turbochargers produce 21 psi of pressurized air. Quote:
Car&Driver: Some will consider the announcement of the M versions of the BMW X5 and X6 arriving this fall to be heresy, a crime against the enthusiast faithful not seen since the debut of the Porsche Cayenne. Well suck it up fanboy, because the X6 M will lap the Nürburgring faster than the E46 M3. And if you really want to throw stones, blame the success of the Porsche, which demonstrated to BMW that a market exists for sporty SUVs. Both Bimmers—the powertrains are identical—put out 555 hp from a twin-turbo V-8, which is a 5-hp middle finger to the Cayenne Turbo S. The 500 lb-ft of torque in the BMWs, however, is 53 short of that of the top-level Cayenne. Well the 555 hp output is impressive. The 500 lb-ft torque, being 53 lb-ft less than the Cayenne Turbo S was to be expected since the Porsche's engine has a slightly larger displacement (4.8l if I'm not mistaken vs. the BMW 4.4l). But even that is quite impressive Car&Driver: If You Have to Ask, You Can’t Afford One Pricing has not been announced, but the beastly BMW X6 xDrive50i starts at $67,475 and doesn’t include some features that will be standard on the X6 M. The 500-hp Cayenne Turbo has a base price of $98,515, so it’s reasonable to expect the X6 M to be closer to a hundred grand than ninety. We predict the X5 M to be priced slightly lower. Fuel economy is sort of an afterthought in vehicles like the X5 and X6, but the standard X6 V-8 gets an EPA rating of 12 mpg city and 18 mph highway, and the M versions are sure to be slightly worse. As silly as these things seem, we’re looking forward to getting some test numbers; that should prove very interesting.

Interesting.
I will have to fight tooth and nail to convince my party that this is what should be in the driveway. BUT if this thing really is at MSRP 100K, even I will have to take the latter (50i). There are are some real nice cars that fall around that 100K range, some that appeal way more to those in my household than my desired M. Let the fun begin.

Must have been the turbo lag Thanks, I know it's working now, it was just weird the way it counted past 0...
