Meet the new Porsche 718 Boxster and Boxster S

The rumors were mostly true. Porsche had already confirmed that the Boxster and Caymans would receive a "718" appended to their badges, in honor of their famous mid-engined racecar of the 1950s and '60s, but the mechanical details were left up in the air. We were almost certain both would be powered by turbocharged flat-fours of a couple of displacements and outputs, and now we can confirm that this is the case. Porsche has revealed the official specs for the 718 Boxster, which will go on sale in Europe this April. The biggest news concerns the flat-fours. The regular 718 Boxster will get a 2.0-liter, turbocharged flat-four producing 300 hp. The 718 Boxster S will get an extra half-liter of displacement and a variable-geometry turbocharger to produce a total of 350 hp. This represents a 35 hp gain over the current Boxster and Boxster S, respectively. Porsche also claims the turbo fours improve fuel economy by around 13 percent. By the NEDC European test cycle, the 2.0-liter gets roughly 34 mpg and the 2.5 gets 32 mpg, although rest assured that EPA test results will yield different numbers than the optimistic European test. Torque gains with the new boxer fours are significant. The 2.0-liter gains 74 lb-ft of torque for a total of 280 lb-ft from 1,950 to 4,500 RPM. The 2.5 gains less, 43 lb-ft, for a total of 309 lb-ft over the same rev range. The extra torque and wide torque band make the 718 Boxster quicker to 60 mph, at least when equipped with the PDK gearbox and the Sport Chrono Package. The 2.0-liter car does the deed in 4.5 seconds, a 0.7-second improvement, and the 2.5-liter car is claimed to hit 60 mph in 4.0 seconds, a 0.5-second improvement. 2016 Porsche 718 Boxster View 11 Photos Inside, a new dash houses the latest Porsche Communication Management infotainment system with a touchscreen, included on all 718 Boxsters as standard – although nav is an optional extra. The buttonless, capacitive-touch center stack we just spied on the next Panamera does not make it inside the 718 Boxster, which makes do with a very similar button layout to the current car. Both cars will come with a six-speed manual as standard, which is great news, and a PDK will be optional for both. Porsche also claims to have made the electrically-assisted steering more direct, and retuned the suspension. An optional PASM package lowers the car by 0.4 inches while providing the benefits of active dampers. From a styling standpoint, this is an evolution of the current theme.

Porsche 918 Spyder pre-production version in all its almost-done glory

Porsche continues the long tease of its upcoming 918 Spyder, with the latest instantiation here at the Pebble Beach Concours, with the car presented in pre-production form to the throngs on the golf course.
Just a few days ago Porsche dropped an image of the car on its official Twitter feed. True to that leak, this 918 looks damn near what we expect the full customer version to be when it is officially debuted in Frankfurt. The neon-green brake calipers are items new to this version of the 918, and seem to be an identical color to those found on the Panamera S E-Hybrid.
When it shows up as a drivable piece, expect the Porsche supercar, with its gasoline-electric drivetrain, to be pretty insane. Horsepower in excess of 800 ponies will be available with a toe-tap, while the price of entry is expected to come within shouting distance of $850,000. A good deal for Porsche to bring the thing to Pebble then, where buyers with that kind of cash are think on the ground (and most likely wearing sherbet-colored trousers).

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.
