Ferrari published a new photo gallery of its tweaked 599 GTB Fiorano with the Handling GT Evoluzione sport package. Revealed for the first time at this year's Geneva Salon, the HGTE is in essence an optional pack designed to further improve driver involvement and agility, as well as to enhance the standard 599 GTB Fiorano's grip.

At a first glance it looks no different than the standard version. The car is fitted with newly designed 20 inch alloy wheels wrapped in high-performance tires while there's also a more aggressive front grille and new chromed tail pipes that promise to deliver a throatier exhaust sound. Besides that, a modified magnetorheological damper settings for improved body control while the 599 GTB's interior has been enhanced with sportier seats embroidered with the words "Handling GTE" and plenty of carbon-fibre trim.

Recently, Nissan has released the NISMO 370Z for the JDM 370Z. The JDM NISMO 370Z features the same upgrades as its American counterpart including a modified version of the 3.7-liter V6 engine that churns out 350 horsepower compared to the standard car's 332HP. Only difference is that while the US-spec model is offered exclusively with a 6-speed manual gearbox, Japanese buyers may also opt for the 7-speed automatic transmission.

NISMO Nissan 370Z JapanThe NISMO package also ads 19-inch alloy wheels shod in 245/40 R19 tires up front and 275/35 R19 at the rear, stiffer suspension and a high-performance brake system.

The coupe's exterior styling is modified with a functional aero kit that includes an extended nose, unique rear fascia, large wing and specific side sills, while the interior is upgraded with a set of sport seats, special door trims and NISMO gauges plus contrasting red stitching on the seats, steering wheel, gearbox knob and handbrake lever. In Japan, Nissan has priced the NISMO 370Z at 4,935,00 Yen (about $51,400 US) for the 6-speed manual gearbox model and at 5,040,000 Yen (approx $52,500 US) for the automatic version.

Not long ago, there are new details released for both the 2010 Mercedes-Benz S63 AMG and S65 AMG facelifts. With a starting price of €115,700 before tax, the S63 AMG short-wheelbase brings a 525 horsepower, 6.3-liter V8 engine producing up to 630 Nm of torque. A long wheelbase model is available for an additional €6,000.

At €185,900 the S65 AMG is hardly cheap, but the 612 horsepower delivered by the 6.0-liter biturbo V12 may be enough to convince new customers. The V12 able to produce 1000 Nm of torque and able to accelerate from 0 to 100km/h at 4.4 seconds, 0.2 seconds faster than the S63. Both cars are electronically limited to 250 km/h. On the S63 the driver controls the AMGSPEEDSHIFT 7G-Tronic transmission, while the S65 utilizes a five-speed automatic.

Impressively, Mercedes did not have to degrade the performance of these two vehicles to improve fuel economy. Both "consumption and CO2 emissions" were reduced "by up to 3 percent."

For the exterior, it seems many of the 8,000 current S-Class AMG customers may get a little jealous. A new arrow-shaped radiator grille - with twin chrome louvres on the S65 - is an effective status symbol on a car that commands respect. AMG-spec LED daytime lights are mounted just above the air outlets on either side of the front apron.

At an angle, this leads nicely into the new sidesills, which blends with the new side mirros to form a defined line to the car's rear. At the back, a new rear apron has a body-color diffuser built in, replacing the black diffuser on previous models. 52 LEDs are shaped in a "double 'C'" pattern to make up the taillights. Redesigned quad exhaust pipes appear in chrome. "6.3 AMG" and "V12 Biturbo" badging is featured prominently.



The two cars separate at the wheels, where the S63 uses 19-inch multispoke wheels, while the S65 uses a 20-inch set. Both wheels are painted in Titanium grey, with glossy finishes. The bigger wheels can be purchased as an option on the S63.

A healthy amount of equipment comes standard, including the Active Body Control AMG sports suspension. ABC provides stabilizes the car when gusts of wind blast the vehicle from the side. The system adjusts "the wheel load distribution within milliseconds" and works with the Electronic Stability Program to reduce the effects of crosswinds. Torque Vectoring Brakes improve cornering by adjusting the caliper pressure on the inner rear wheel. AMG Adaptive Brakes are also included, using a double floating brake caliper at the front.

Back into the cockpit, the S-class AMG comes with a healthy amount of leather, and multifunctioning AMG sport seats which will gladly give you a massage should you need one. Both vehicles feature the AMG analogue clock, and AMG aluminum shift paddles that connect to a Direct Select gearshift. A piano black lacquer crossed with carbon fiber AMG trim is also available.
