Porsche Macan And 918 Spyder And The 2019 Los Angeles International Auto Show

ue4与工业设计mercedes-benz s63 amg cabriolet 2017Porsche Macan and 918 Spyder and the 2013 Los Angeles international auto show. LAAutoshow and this year they outdid themselves with the world premiere of the Macan and US premiere of the 918 Spyder. I was not overly excitable when I heard about the just released Macan, thinking it may be to much of a Q5 lookalike, until I saw it in person. PorscheMacan has been designed very well, is pleasing to the eye and is going to be a popular addition to the Porsche stable setting the benchmark for the compact SUV market. Both the Macan S and the Macan Turbo are powered by twin-turbo V6 engines. 49,900, will come with all wheel drive and 7 speed Porsche Doppelkupplung PDK transmission and a 3.0 liter, 340hp engine with 339 lb-ft of torque. With the optional sport chrono package, you will be able to blast from 0-60 mph in 5.0 seconds to a top speed of 156 mph. Not bad for the base model. 72,300 will have the Porsche Active Suspension Management (PASM), adaptive sports seats, Leather package, navigation and BOSE surround sound in addition to the S and will also have the PDK transmission.

The engine is 3.6 liter with an output of 400hp at 6000rpm. 406 ft-lbs of torque and the optional sport chrono package propel the Macan Turbo to 60 mph in 4.4 seconds, with a top speed of 164 mph. The US premiere of the electric hybrid 918 was at Los Angeles. The 918 is to be built in limited numbers and will quickly be snapped up by collectors and speculators. This race hybrid has, 4 wheel drive, a 4.6 liter V8 which revs to 9150rpm and has 608 HP and 2 electric engines with a combined output of 887 hp. The 918 Spyder with all engines ago will launch to 60 mph in 2.8 seconds and is capable of a 0-60 mph run of 7 seconds in full electric mode. The 918 Spyder also is capable of a sub 7 minute run on the Nurburgring, which puts it in the legendary category. Look for it at a charging station near you.


“The Corvette Z06 is a great example of the technology transfer between racing and production Corvettes,” said Tadge Juechter, Corvette chief engineer. “First, we took what we learned on the Corvette Racing C6.R and applied that to the all-new Corvette Stingray. The heart of the 2015 Corvette Z06 is the all-new LT4 6.2L supercharged V-8 engine, expected to deliver an estimated 625 horsepower (466 kW) and 635 lb-ft of torque (861 Nm). To balance performance and efficiency, the LT4 leverages the same trio of advanced technologies introduced on the Corvette Stingray: Direct injection, Active Fuel Management, or cylinder deactivation, and continuously variable valve timing. These technologies - combined with the fuel-efficient multi-speed transmissions, aerodynamic design and lightweight construction - help make the new Z06 surprisingly fuel efficient. “The supercharged LT4 engine delivers the greatest balance of performance and efficiency ever in the Corvette,” said John Rydzewski, assistant chief engineer for Small-Block engines.


To maintain the Z06’s mass and performance targets, the LT4 engine was designed with a more-efficient, more-compact supercharger. Standard dry-sump oiling system with larger cooler capacity than Z51; used with dual-pressure-control oil pump. The LT4 will be built in Tonawanda, N.Y., and at the new Performance Build Center in Bowling Green, Ky. The supercharged LT4 is offered with a standard seven-speed manual transmission with Active Rev Match, or an all-new 8L90 eight-speed paddle-shift automatic transmission designed to enhance both performance and efficiency. “Unlike most ultra-performance cars, the Corvette Z06 offers customers the choice between two transmissions to suit their driving styles,” said Juechter. “The seven-speed gives the driver the control of a true three-pedal manual transmission with perfect shifts enabled by Active Rev Matching. The seven-speed manual incorporates rev-matching technology for upshifts and downshifts. This driver-selectable feature can be easily engaged or disengaged via paddles on the steering wheel. The seven-speed is used with a new dual-mass flywheel and dual-disc clutch, which deliver greater shift quality and feel through lower inertia.


“There’s no trade-off in drivability with the new 8L90 eight-speed automatic transmission - it was designed to deliver performance on par with dual-clutch designs, but without sacrificing refinement,” said Bill Goodrich, assistant chief engineer for eight-speed automatic transmissions. Featuring four gearsets and five clutches, creative packaging enables the GM-developed eight-speed automatic to fit the same space as the six-speed automatic used in the Corvette Stingray. Extensive use of aluminum and magnesium make it more than eight pounds (4 kg) lighter than the six-speed. Along with design features that reduce friction, the 8L90 is expected to contribute up to 5-percent greater efficiency, when compared with a six-speed automatic. The eight-speed automatic will be built at GM’s Toledo, Ohio, transmission facility. The performance targets of the Z06 also posed a challenge for the design team, which had to create a striking design that also contributed to increased capabilities. “Practically every exterior change served a functional purpose, as this beast needed more of everything,” said Tom Peters, Corvette design director, “The flared fenders accommodate larger, wider wheels and tires for more grip.
