Porsche updates 919 Hybrid racer for 2015 season

Porsche's grand return to the elite level of global endurance racing showed mixed success in its first year. The company did score one victory in the 2014 FIA World Endurance Championship season during the race in Brazil but finished in third place overall among the three factory manufacturers. Porsche is hoping for a few more wins in 2015 and is releasing its first shots of the updated car to achieve those triumphs when things kick off in April. The team's racer is still called the 919 Hybrid, but Porsche promises this second-generation version is a "comprehensive evolution" compared to last year. The most obvious change is the redesigned front end where the styling now features a simple horizontal intake running across the front (compare to 2014, below). The nose area also now flares out to the windshield. The side grows a more complicated look, though, with a series of fins just behind the driver compartment. Porsche isn't divulging many details about anything different under the skin. The 2015 919 is still propelled by a 2.0-liter turbocharged V4, and an electric motor powers the front wheels. There are also two energy recovery systems. In addition to the previous challengers from Audi and Toyota, Porsche has one more competitor in the factory ranks this season. The Nissan GT-R LM Nismo is rumored to be a radical departure from the rest of the field with an engine possibly located in front of the driver.

Extensive testing with the second generation of Porsche's Le Mans prototype will begin on January 18, on Abu Dhabi's Yas Marina Circuit. As scheduled, this marks the start of the 2015 motorsport season for the Porsche Team. The new Porsche 919 Hybrid has already had its roll-out on the Weissach test track. As a next step, there will be several performance and endurance tests before the WEC season opener on April 12 in Silverstone, Great Britain. The new Porsche 919 Hybrid is a comprehensive evolution of the successful car that made its debut in 2014. It will feature the same innovative drivetrain concept consisting of a 2-litre V4 turbocharged petrol engine, an electric motor powering the front wheels, and two energy recovery systems. The new generation car had its first roll-out on December 15, 2014.

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 Panamera 4 E-Hybrid has 462 hp and 516 lb-ft of torque

Hybrids are for more than saving fuel, according to Porsche. To wit, the German automaker's upcoming 2018 Panamera 4 E-Hybrid boasts 462 horsepower and 516 pound-feet of torque courtesy of its 2.9-liter twin-turbo V6 (330 hp and 331 lb-ft) and electric motor (136 hp and 295 lb-ft). All that power is sent to all four wheels through an eight-speed PDK transmission, resulting in a 4.4-second 0-60 run and a top speed of 172 miles per hour. For those keeping track at home, those performance stats put the E-Hybrid a few ticks behind the 2017 Panamera 4S, which uses a more powerful version of the twin-turbo V6 engine to hit 60 in 4.0 seconds (with the optional Sport Chrono package). The payoff, though, is in efficiency. There's a maximum electric range of 31 miles with a fully charged battery, and the engine isn't needed until speeds top 86 mph. That means the majority of drivers won't need to use a drop of gas for most daily driving chores. The E-Hybrid ought to be pretty fun to drive, too. In the previous Panamera Hybrid, the accelerator pedal had to be pressed at least 80 percent of the way down to get maximum electric motivation. For the new version, every electric horse is available at all times. Coupled with the nature of turbocharged engines, we'd imagine there's going to be a lovely wave of torque at around-town speeds and on highway on-ramps. A liquid-cooled, 14.1-kWh, lithium-ion battery is located under the floor of the cargo area. It takes 12 hours to charge on a standard outlet, or as little as 3 hours with an optional high-speed charger. As with other Panamera models, most of the interior buttons have been replaced with touch-sensitive panels. E-Hybrid models get unique programming for the dual 7-inch displays in the dash and the 12.3-inch touchscreen atop the center stack that shows various power meters and driving tips to increase efficiency. Porsche's Sport Chrono Package comes standard on the Panamera E-Hybrid. In addition to the Sport and Sport Plus modes of the steering-wheel-mounted mode switch, there's an E-Power mode that relies solely on electricity, a Hybrid Auto mode for maximum gas/electric efficiency, an E-Hold setting that switches the car into gas-only mode to preserve the battery, and an E-Charge mode that forces the gas engine to keep the battery fully charged. If you want maximum performance, you'll want to keep the switch in Sport Plus. Expect the 2018 Porsche Panamera E-Hybrid to hit US showrooms this summer.
