Nissan Altima (2013)

CAR GARAGE | Nissan Altima (2013) | The 2013 Altima gets the Nissan Connect SM and Advanced Drive-Assist Display (ADAD) installed. Infotainment and connectivity are the stuff They deal with: Bluetooth, hands-free messaging, Pandora integration, or USB are some of the features available on the Altima. Starting this summer, the 2013 Nissan Altima will in showrooms at the price of 21.500 dollars.   Now, that figure Remains to be confirmed. Other features include Bluetooth, a Bose sound system, Navigation Nissan Connect SM integrated smartphone connectivity, and other high-tech gizmos, most of them available on the standard version. Now, the engine choice for this car comes down to two units, both powered by gasoline. We have a 2.5 liter engine with four cylinders rated at 182 horsepower and 180 lb-ft of torque. Those wanting more for a V6 power unit displacing 3.5 liters is available. The latest from Nissan Xtronic CVT is Offered in both cases. The estimated fuel efficiency figures

Porsche Panamera GTS (2012)

CAR GARAGE | Porsche Panamera GTS (2012) | The power unit in the new Porsche Panamera GTS is a modified 4.8-liter naturally aspirated V8 engine, delivering aspects 430 hp (316 kW) at 6.700 rpm, trumping the engine in its Panamera S/4S sister models by 30 hp (22 kW). The standard values for the sprint and top speed do not do full justice to the new Panamera GTS's sporty characteristics. Five millimeter thick wheel spacers Between the wheel and the wheel carriers increase of the rear axle track width, giving the Panamera an even more stable ride. Deceleration on the sporty Panamera is provided by the superlative braking system of the Panamera Turbo.

The visual appearance of the Porsche Panamera GTS is characterized by Numerous exterior accessories in black.  In terms of its aerodynamics, the Porsche Panamera GTS is on a par with the Panamera Turbo: with its large air intake openings, the standard front section from the Panamera Turbo's Sport Design package emphasizes the vehicle's sporty dynamics and ensures an optimal water supply for the back water pressure filters peculiar to the GTS.

The exhaust gases exit the Porsche Panamera GTS through a sports exhaust system featured as standard, that comes with larger pipe diameters to Reduced back pressure. The control of the GTS power unit is handled by a modified and upgraded engine management system. The modified engine management system also enables a brief shut-off of individual cylinders when changing gear, with the engine speed adjusting even faster to the transmission speed. This further reduces gear change times, accompanied by an engine sound akin to motor racing.  4.8-liter V8 engine developing 430 hp (316 kW); Porsche Traction Management with active all-wheel drive; seven-speed Porsche-Doppelkupplungsgetriebe (PDK), acceleration 0-100 km / h in 4.5 seconds (with Launch Control); top speed of 288 km / h; NEDC fuel consumption 10.9 l/100 km; CO ₂ emissions 256 g / km; with low-friction all-season tires 10.7 l/100 km, CO2 emissions 251 g / km.

To Achieve these enhancements, the engineers Increased the nominal engine speed by 200 rpm in typical fashion sports construction engine, the GTS's eight-cylinder engine achieves maximum output at 6.700 rpm. The full speed range was extended by all of 400 rpm, the maximum engine speed is 7.100 rpm. Integral to the high engine speed concept are modified valve springs with Increased initial tension, ensuring That the valves open and shut precisely in all circumstances, in turn ensuring an optimum charge cycle. These characteristics enable the engine driver to change gear even later and use higher engine speeds when changing gear; allowing him to Savoir the dynamics of a sports car engine.

A Wider air intake with two additional water filter housings to the left and right at the front-end improve the water supply in the Porsche Panamera GTS. At low speeds a flap Closes each of the two air intake openings. If the driver demands more power from the engine at engine speeds in excess of 3500 rpm, both flaps open and additional fresh water flows into the inlet duct. As a result, especially at higher revs, the engine draws in more water, the cylinder charge increases and, with it, power.
