•  Porsche 911 Carrera 4 GTS, 2012

Porsche AG is widening the top end of its Carrera model line and pairing up each of the two 911 Carrera GTS with an all-wheel drive twin. That means that the Porsche 911 Carrera 4 GTS Coupé and Cabriolet will combine the 408 hp (300 kW) top of the range engine of the Carrera GTS family with the intelligent, all-wheel drive Porsche Traction Management (PTM). Driving dynamics are not the only source of attraction. Economics are as well. Thanks to Porsche Intelligent Performance the new all-wheel 911s consume no more than the equivalent Carrera 4S version, the Coupé remains at 11.0 l/100 km (25.7 mpg imp.) and the Cabriolet at 11.2 l/100 km (25.2 mpg imp.) respectively based on the New European Driving Cycle (NEDC). Moreover both of them boast an even more comprehensive standard equipment package compared with the Carrera 4S models.

The Porsche 911 Carrera 4 GTS power unit has its origins in the 3.8-litre, six-cylinder Carrera S engine. A wholesale revamping of the intake duct added 23 hp (17 kW), taking the power output to 408 hp (300 kW) at 7,300 rpm. The special aspiration system not only improves peak power output but flexibility and power development as well thanks to a more generous torque curve in the lower and middle engine speed range. 320 Newton metres kick in from as low as 1,500 rpm; the six-cylinder engine delivers its rated torque of 420 Nm in the broad engine speed range from 4,200 rpm and 5,600 rpm. The sports exhaust system fitted as standard ensures a distinctly sporty sound. It invests the new Porsche 911 Carrera 4 GTS with an unmistakable acoustic signature and the rear view of its tail pipe with its unique black surface design lends it a unique character.
At full power the Porsche 911 Carrera 4 GTS Coupé sprints to 100 km/h (62 mph) in 4.6 seconds, the Cabriolet in 4.8 seconds. The Carrera 4 GTS is fitted as standard with a six-speed manual transmission but the Porsche-Doppelkupplungsgetriebe (PDK) seven-speed is available as an option if desired. The PDK shaves an additional 0.2 seconds respectively off the acceleration times from 0 to 100 km/h (62 mph).

In the Porsche 911 Carrera 4 GTS as well, PTM all-wheel drive stands for Porsche's typical driving pleasure with even more driving stability, traction and agile handling. The PTM achieves this by directing the optimal proportion of the engine torque to the front wheels via a multiple-plate clutch. What's more, just how single-mindedly the Porsche 911 Carrera 4 GTS is designed for driving dynamics is evident from the use of a standard limited-slip differential. This mechanical rear differential lock contributes to the driving dynamics of the electronically controlled all-wheel drive system.

Visually, the new Porsche 911 Carrera 4 GTS models with all-wheel drive differ in points of detail from earlier variants with rear-wheel drive: In addition to the type name on the doors and rear lid, the distinguishing characteristic of all models with all-wheel drive is the additional reflective stripe between the taillights. What the Carrera GTS models have in common is the 911's wide body, otherwise reserved for the all-wheel version of the 911s, and the rear axle track width that goes with it. In numerous other details as well the GTS models differ both visually and technically from the other Carrera models. For example, they run on 19 inch RS Spyder wheels in black with central locking and gloss-lathed rim flanges fitted with 305/30 ZR 19 tyres on the rear axle.

Additional visual features include the Sport-Design front apron with black painted spoiler lip and special side skirts, also in black. Driver and passenger are accommodated on sports seats. Typical of the GTS, the emphatically sporty black Alcantara covering on centre panels, steering wheel rim, gearshift and handbrake lever, door handles and door storage box lid and extension are offered as standard in addition to a range of leather upholstery options.

The Porsche 911 Carrera 4 GTS Coupé, including country-specific equipment and VAT at 19 per cent, is offered in Germany at a price of 111,956 euro, the Cabriolet costs 122,071 euro. Both models will be on sale in Germany from July 2011.

Pontiac Vibe, 2009

 

 

 

1.  Pontiac Vibe, 2009

The all-new 2009 Pontiac Vibe is a modern re-mix of a classic hit, infusing the functionality of a compact crossover with a bolder attitude of muscular styling, increased performance and tight handling. It arrives in dealer showrooms in early 2008.

Adding a richer harmony to the tune, the popular all-wheel-drive and GT models return to the Vibe lineup. Regardless of the model, each Vibe offers a level of athletic design, boosted performance and everyday versatility uncommon in the price range.

Engine performance
Packing more off-the-line power than ever before, the '09 Vibe delivers the type of responsive performance needed to safely navigate those unexpected everyday driving situations. A 132-horsepower (98 kW) 1.8L DOHC four-cylinder is standard on base models and delivers 128 lb.-ft. (174 Nm) of torque. The engine benefits from dual variable valve timing, optimizing both performance and efficiency, and is matched to a standard five-speed manual transmission or optional four-speed automatic.

Customers desiring higher performance can opt for the larger, 2.4L DOHC engine with 158 horsepower (118 kW) and 162 lb.-ft. (224 Nm) of torque. The 2.4L engine is standard on AWD and GT models, and is optional on the base model.

A four-speed automatic transmission is standard on the AWD. Customers of the 2.4L-equipped base or GT models can choose between a standard five-speed manual transmission or a new, five-speed electronically controlled automatic transmission featuring Driver Shift Control (DSC), which delivers a great combination of performance, fuel economy and smoothness. With DSC, the driver can manually select gears via tap up/tap down controls.

Fuel economy
With the 1.8L engine and the standard manual transmission, EPA fuel economy is estimated at 26 mpg in the city and 32 mpg on the highway; with the automatic, fuel economy is estimated at 25 in the city and 31 on the highway.

The 2.4L engine on the GT is estimated at 21 mpg in the city and 28 on the highway with the manual transmission and 21 city/29 highway with the five-speed automatic. On the AWD model, the 2.4L/four-speed automatic combination delivers an estimated 20 mpg in the city and 26 on the highway.

Ride and handling
Driving dynamics of the new Vibe have been refined to deliver a responsive driving experience, with a special focus on reduced noise, vibration and harshness. An array of chassis control systems enhances ride and handling, as well as safety.

The Vibe has a body-integral structure with underbody rails running from front to rear, giving the structure exceptional strength and a strong foundation on which to anchor the suspension systems. All models employ a MacPherson-strut front suspension design. The base model has a torsion-beam rear suspension that is revised for a more comfortable ride, while the AWD and GT models use a multi-link independent rear suspension for even sharper responses and enhanced driving control.

Four-wheel disc brakes with ABS are standard on all models, as is electronic stability control and traction control. Steering control is augmented with an electric power steering system, providing variable-effort performance and (because there is no engine-driven power steering pump) enhanced fuel economy.

Exterior design
The Vibe has the looks to back up its performance. With a lean, athletic form, the Vibe's new exterior exemplifies the future of Pontiac's design - clean, purposeful shapes and a decidedly sophisticated aesthetic. The new Vibe's appearance melds the space-enabling design of a small SUV with a forward-looking profile, furthering the groundbreaking design pioneered by the original Vibe, launched in 2002.

All of the sheet metal is new, with minimal gaps that reinforce the Vibe's tailored appearance. A faster windshield angle contributes to the sleeker look, while large wheels and minimal overhangs give the vehicle an aggressive, firmly planted stance.
Vibe's three models - base, AWD and GT - are distinguished from one another with unique styling cues. For example, the AWD features a standard roof rack perfect for outdoor activities. The GT has its own front fascia - with larger fog lamps and lower-fascia air intake - rocker moldings, roof spoiler and a bright exhaust tip. All models offer distinctive wheel options.

Interior design and features
Like the exterior, the '09 Vibe's interior is all-new and has a driver-focused cockpit design more common to sports cars. The controls and gauges were redesigned for easier use, but retain a performance-oriented look and feel; and the interior quality and craftsmanship are reflected in class-leading gap/flush tolerances.

Interior material refinement is also stepped up a notch in the new Vibe, with a combination of low-gloss materials, varied grains on the instrument panel and other trim components, and satin-metal accents. New, knit-fabric seating surfaces are durable and have a premium look, while GT models are enhanced with standard leather-trimmed seats, three-spoke steering wheel and shift knob. Seating for five is standard on all models.

The Vibe's interior also is loaded with standard amenities not typically found in other vehicles in the segment, including a steering column with telescoping/rake adjustability; a 115-volt, three-prong auxiliary power outlet, six-way adjustable driver's seat and front active headrests.
