Porsche 918 Spyder officially priced from $845K, Weissach package $84K more

Porsche has released official pricing for its entire lineup of 2013 models, which just happens to include the upcoming 918 Spyder hybrid supercar. The 795-horsepower advanced-technology-lab-on-wheels is now officially confirmed to have a starting price of $845,000 in the US, which is the exact amount we were told earlier when we had the opportunity to ride shotgun in some 918 Spyder pre-production test vehicles.
What we didn't know at the time was the cost of the Weissach trim package, which is a high-performance upgrade to the standard vehicle that includes the deletion of some interior amenities and addition of lighter-weight carbon fiber appointments, magnesium wheels, flame-resistant upholstery, racing belts and aerodynamic aids - it's meant for track-going folk who intend to use their 918 Spyders as God, country and manufacturer intended.
All told, the Weissach package should drop the 918 Spyder's curb weight by some 80 pounds, while also lightening your wallet of an additional $84,000 - the car's MSRP with the Weissach package is $929,000. These prices don't, however, include destination charges, which, for something like the very limited edition 918 Spyder (only 918 will be made), could very well cost considerably more than your average Porsche.

Porsche Cayenne diesel V8 may not be long for this world

Goodbye, Porsche Cayenne V8 Diesel. We hardly knew ye. Nor did the Europeans, apparently. Porsche's V8 oil burner is still on the European model list for the Cayenne SUV, but the mill won't go through the likely pricey process of being updated to adhere to new and stricter European emissions standards, Just-Auto says. A Porsche spokesman confirmed to the publication that it's a fairly complicated process to update the diesel V8 to be so-called "Euro-6 compliant." With Cayenne diesels selling in relatively low volumes anyways, the German automaker might just dump the V8 diesel altogether, as it'd be quite cost-ineffective to make the necessary upgrades. The V8 diesel was a 4.1-liter engine that delivered 385 horsepower in addition to what sounds like a little too much exhaust for European clean-air regulators. While that's a pretty powerful profile, the most recent gas-powered V8 for the Cayenne delivers about 570 horsepower, so the diesel engine won't likely be missed by European auto enthusiasts. Besides, there's still the V6 diesel that's also sold in the US. That's a 4,800-pound beast that moves from 0 to 60 miles per hour in about seven seconds and gets a relatively (for diesels) modest 20 miles per gallon city. For those who are curious, Autoblog's First Drive review of that model can be found here.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
