2015 Porsche Panamera S E-Hybrid

When the Porsche Panamera joined the hybrid poker game with the S Hybrid, it started with a seat at the penny-ante table: engineers inserted a 47-horsepower electric motor between the gas engine and eight-speed automatic, powered by a 1.7-kWh nickel-metal hydride battery. It was tiny stakes, the kind of non-risk taken when you're trying to figure out both how to play the game and how you want to play the game. After two years of experimenting, the 2015 Panamera S E-Hybrid makes a bigger bet – the kind that requires paper bills and the maxim, "If you can't fold it, hold it." Porsche's plug-in hybrid gets every adjective we expect of a successor from Stuttgart: more complex, more efficient, more powerful and faster. Driving Notes The electric motor leaps from 47 hp to 95 hp thanks to more windings on the stator coils and new power electronics. The battery goes from a 1.7-kWh nickel-metal hydride unit to 9.4-kWh lithium-ion setup; it's the same physical size as before, still mounted under the cargo deck. Internal combustion still comes from the Audi-sourced, 333-hp, supercharged V6, but total system power goes from 380 hp and 428 pound-feet of torque in the S Hybrid to 416 hp and 435 lb-ft in the S E-Hybrid. The previous system could run a mile on electricity, this one is estimated to last more than 20 miles on e-power on the European cycle. The 0-60 dash takes 5.2 seconds, down from 5.7 seconds; top speed in electric-only mode is 84 mph – up from 50 mph. It takes 2.5 hours at a 240-volt outlet to fully recharge the battery; the Porsche Universal Charger comes equipped with a cable for that and a standard 120-volt socket. Only Panamera obsessives will notice the sheetmetal changes for 2015, but there are sharper lines on the front and rear fascias, faint revisions made to the light clusters, wider glass – over the same-sized opening – on the rear tailgate, and a wider rear spoiler. Outsiders will know the S E-Hybrid because of Acid Green highlights on the fender and tailgate logos, as well as the Acid Green brake calipers. Inside, the central tach remains, but the analog speedometer was evicted to make space for the battery power meter, and Acid Green needles dance across all the gauges. The navigation screen shows your electric driving range and the Porsche Car Connect service provides the expected, smartphone-controlled e-mobility features.

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.

Porsche Australia racing chief dies in crash

The motor racing community in Australia was saddened today to learn of the passing of Jamey Blaikie, a longtime racing administrator and former motorsport director for Porsche in Australia. A former racing driver in his own right, Blaikie was better known for his instrumental role in starting the Porsche Carrera Cup in Australia back in 2003. He left Porsche Cars Australia just last year to pursue other interests, including running an Aston Martin entry in the GT Asia series. Blaikie was in Fiji reportedly undertaking charity work there when his rental car collided with a truck, prematurely ending his life at just 52 years old. Our condolences go out to his family, friends and the motorsport community Down Under, where he'll surely be missed.
