Chevrolet Caprice Police Patrol Vehicle, 2011

 

Chevrolet Caprice Police Patrol Vehicle, 2011

An all-new Chevrolet Caprice Police Patrol Vehicle (PPV) will join the ranks of law enforcement departments across North America in 2011. It's a modern, full-size, rear-drive sedan that will offer both V-8 and V-6 engines, as well as a host of specialized equipment and features.

Chevrolet made the announcement at the annual International Association of Chiefs of Police convention, in Denver, Colorado. The Chevrolet Caprice PPV will be available for ordering next year and will hit the streets in early 2011.

Unlike other police cars on the market, the Chevrolet Caprice PPV is not based on existing "civilian" passenger-car model sold in North America. It has been developed in key areas specifically for police duty, containing modern equipment and features:

    * Powerful 6.0L V-8 with fuel-saving Active Fuel Management technology and E85 capability delivers expected best-in-class 0-60 acceleration (sub six seconds) and top speed; a V-6 engine will also be offered, beginning in the 2012 model year
    * Optional front-seat-only side curtain air bags allows a full-width rear-seat barrier for greater officer safety
    * Two trunk-mounted batteries, with one of them dedicated to powering various police equipment
    * Designed for five-passenger seating, meaning the upper-center section of the dashboard can be used for equipment mounting without the concern of air bag deployment interference
    * Compatibility with in-dash touch-screen computer technology
    * Special front seats designed for the long-term comfort of officers whose car is their effective office, including space that accommodates the bulk of a typical equipment belt

The front seats are sculpted to "pocket" the equipment belt, which greatly increases the comfort for a great range of police officer sizes. The foam density of the seatback and cushion insert surfaces are designed to conform to the shape of an equipment belt's various items, too, allowing the officer's back to rest properly on the seatback surface.

Along with comfort, the materials used in the seats were also carefully selected. High-wear materials were chosen to stand up to long hours of everyday use, while breathability, long-term durability and ease of cleaning were also important criteria.

Engineers worked on several iterations of the seat, testing a couple of versions in the field to get real-world feedback from police officers, who used prototype seats in their cruisers for a month. Their input helped determine the final design.

Class-leading space
The Chevrolet Caprice PPV is based on GM's global rear-drive family of vehicles that also underpins the Chevy Camaro. It uses the longest wheelbase of the architecture - 118.5 inches (3,010 mm) - along with a four-wheel independent suspension that delivers responsive high-performance driving characteristics that are crucial in some police scenarios.

Chevrolet Caprice Police Patrol Vehicle's long wheelbase also contributes to exceptional spaciousness. Compared to the primary competition, its advantages include:

    * A larger interior volume - 112 cubic feet / 3,172 liters - than the Ford Crown Victoria, including nearly 4 inches (101 mm) more rear legroom
    * The barrier between the front seat and rear seat is positioned farther rearward, allowing for full front-seat travel and greater recline for officer comfort
    * At 18 cubic feet (535 liters) free space (beyond battery located in trunk), the Caprice's trunk volume is large enough to accommodate a full-size spare tire under a flat load surface in the trunk storage area.

The Chevrolet Caprice's 6.0-liter V-8 is rated at an estimated 355 horsepower (265 kW) with an estimated 384 lb-ft of torque. It is backed by a six-speed automatic transmission that is performance-calibrated for police duty. Additional, police car-specific powertrain and vehicle system features include:

    * High-output alternator
    * Engine oil, transmission and power steering coolers
    * Standard 18-inch steel wheels with bolt-on center caps
    * Large, four-wheel disc brakes with heavy-duty brake pads
    * Heavy-duty suspension components
    * Police-calibrated stability control system
    * Driver information center in the instrument cluster with selectable speed tracking feature.

A host of complementary features are also offered, including special equipment packages such as spotlights; lockouts for the power windows and locks; and an "undercover" street-appearance package (9C3).

To enable more room for interior equipment, the standard radio can be relocated to the trunk, allowing for an in-dash, touch-screen computer to be used.

Chevrolet Caprice on patrol: A brief history

Chevrolet's history with law enforcement is almost as old as the brand itself. Police departments have used Chevy sedans as police cars for decades, ordering them with basic equipment and powerful V-8 engines - including some special engines that weren't available in regular-production models, such as the 1959 Biscayne that was offered with up to 315 horsepower.

The full-size Chevrolets joined the force in 1976. All Chevrolet Caprice police cars - including the new, 2011 model - have carried the 9C1 order code. Here's a quick look back at Chevys on patrol:

    * 1959 - Chevy Biscayne police model capable of 135 mph with specially tuned, police-only version of the 348-cubic-inch V-8 engine
    * 1965 - The new "big-block" 396 engine is offered in Biscayne and Bel Air police cars, making them among the most powerful on patrol; a 427 V-8 was added in 1966
    * 1976 - The 9C1 order code is given for the first time to a full-size Chevy police car package. It carries the Impala name.
    * 1977 - The full-size Chevy is downsized. The 9C1 police package is retained, as is the Impala name.
    * 1986 - The Caprice name replaces Impala, as the car is updated for the mid- and late-1980s - including the option of a powerful, 5.7-liter small-block V-8.
    * 1991 - A new-generation Caprice is launched, with the 9C1 police car still on the beat.
    * 1994 - The 260-horsepower (194 Nm) LT1 V-8 engine is offered in the Caprice 9C1, making it one of the fastest full-size police cars ever offered.
    * 1996 - Caprice police car production ends, as GM's full-size, body-on-frame car architecture is discontinued.
    * 2011 - The Chevrolet Caprice Police Patrol Vehicle returns to active duty.

Chevrolet Corvette Z06 Carbon Limited Edition, 2011

 

Chevrolet Corvette Z06 Carbon Limited Edition, 2011

When the 2006 Corvette Z06 was introduced, it represented the closest connection to the Corvette race cars ever. The 2009 Corvette ZR1 closed the gap between racing and production even further. In 2010, Corvette continues its tradition of track-to-street technology transfer with the 2011 Chevrolet Corvette Z06 Carbon Limited Edition.

The Chevrolet Corvette Z06 Carbon Limited Edition is another example of the expanded Corvette line-up. Five years ago, customers had the choice of a Corvette coupe or convertible. With the addition of the Z06, Grand Sport coupe and convertible and ZR1, Corvette enthusiasts now have more choices than ever.

This limited edition Z06 will boast Brembo carbon ceramic brakes with specific dark gray metallic calipers. These powerful brakes were first introduced on the ZR1. Black 20-spoke 19-inch front/20-inch rear wheels complement the car's Michelin PS2 tires. Other mechanical features include Magnetic Selective Ride Control for the first time on the Z06 and enhanced cooling. The car also features a special carbon pattern engine cover.

The Chevrolet Corvette Z06 Carbon Limited Edition will be available in two colors: Inferno Orange and the all-new Supersonic Blue. Black headlamps and mirrors, a ZR1-style body color spoiler, body color door handles, carbon fiber raised hood, and black carbon fiber rockers and splitter enhance the Z06's dynamic design and reduce mass and aerodynamic lift. For track events, customers can also install the Euro-styled racing numbers that come with each car.

The Chevrolet Corvette Z06 Carbon Limited Edition's ebony leather and suede interior is complemented by blue or orange seat stitching to match the exterior color chosen. Other features include a unique steering wheel emblem, sill plate and logoed headrest. The suede used on the steering wheel, shifter, seat inserts, armrests and doors add to the luxury of this limited edition Z06.

An optional Z07 performance package that includes the mechanical upgrades introduced on the Chevrolet Corvette Z06 Carbon Limited Edition can be added to a regular 2011 Z06. This package also includes Competition Gray 20-spoke wheels and all the chassis and cooling upgrades.

The CFZ Z06 carbon fiber package includes black carbon fiber rockers, splitter and roof panel with the full-width body color spoiler. It can also be purchased with or without the Z07 package on regular Z06 models.

The 2011 Chevrolet Corvette Z06 Carbon Limited Edition, as well as the new Z07 and CFZ Z06 option packages will be available in late summer of 2010.

Bentley Continental Supersports Convertible, 2011

Bentley Continental Supersports Convertible, 2011




The Bentley Continental Supersports Convertible further strengthens Bentley's supercar range, following the introduction of the Bentley Continental Supersports Coupé in 2009. The new Supersports Convertible, with the same 630PS (621bhp/463kW) twin-turbocharged W12 engine, is the fastest, most potent drop-top Bentley has ever built, offering the ultimate Bentley driving experience in the world's most dramatic convertible.

The inspiration for the 'Supersports' name is the 1925 Bentley Supersports, a race-bred version of the iconic Bentley 3-litre, that delivered 85bhp when more ordinary cars were equipped with a modest 15bhp. It was also the first production car to reach 100mph - extreme performance in its day.

The new, muscular four-seat Bentley Continental Supersports Convertible is unmistakably Bentley in its design and craftsmanship but its interiorsignifies a dramatic re-interpretation of Bentley luxury. Satin-finished carbon fibre,Alcantara™and 'Soft Grip' leather create a unique ambience with a distinctly sporting and contemporary style.

All models in the Continental model range, including the new Bentley Continental Supersports Convertible are now capable of running on both petrol (gasoline) and E85 bioethanol or any combination of the two, reaffirming Bentley's ongoing commitment to make all its cars bio-fuel compatible by 2012. Pioneered by the Supersports Coupe, this FlexFuel technology offers a reduction of up to 70 per cent in CO2 emissions on a 'well-to-wheel' basis, a measure of a fuel's net contribution to the atmosphere, not just tailpipe emissions.
Bentley Continental Supersports Convertible

To ensure seamless power delivery, the on-board fuel supply system detects the blending ratio of the fuel in the tank and ensures that power and torque remain constant regardless of the ratio of petrol to biofuel.

The Bentley Continental Supersports Convertible - In Detail
The new Bentley Continental Supersports Convertible is a car that must be driven to be fully understood. Behind the wheel it is immediately clear that a Supersports Bentley is a 'fusion of extremes' - the ultimate in extreme performance, every day practicality and unrivalled hand-crafted luxury.

Bentley's Supersports programme began as an 'under the radar' project exploring the possibilities of weight reduction on the Continental GT Coupé but with more power and torque. The largely experimental project soon crystallised into an official new car programme, driven by the passion and enthusiasm of a small group of Bentley engineers and designers. Now the Bentley Continental Supersports Convertible has received the same focus and the results are equally dramatic. Dr Ulrich Eichhorn, Member of the Board, Engineering explains the thinking behind the project:

A highly focussed, pure Bentley driving experience
With 630PS (621bhp) and 800Nm (590lb ft) of torque from its pioneering FlexFuel engine and new 'Quickshift' transmission, the Bentley Continental Supersports Convertible is the fastest drop-top Bentley has ever built. It accelerates from 0-60mph in 3.9 seconds (0-100km/h in 4.2 seconds) and, conditions permitting, can continue onto a top speed of 202mph (325km/h).

The increased power and torque are transmitted to the all-wheel drive system via an uprated and rapid six-speed Quickshift transmission, which more than halves shift times (to just 93 milliseconds) and maximises the new Convertible's enormous potential. The revised gearbox also has the ability to deliver double downshifts (sixth to fourth gear, for example) and improves acceleration across the entire gear range. To cope with the additional power and torque, the planetary gear set of the ZF transmission is also strengthened.

Positive torque during downshifts is achieved through engine and gearbox electronic controller interaction for extra throttle and fuel injection during the overrun. During transmission upshifts, fuel and ignition are cut momentarily to give faster mechanical shift times through torque reduction, also improving shift quality and durability.

The extreme performance of the Bentley Continental Superports Convertible is matched by precise, agile handling, while retaining class-leading levels of ride comfort and refinement. Developed from the GTC Speed, chassis enhancements include retuning of the electronic Continuous Damping Control (CDC) system, stiffer front suspension bushes and uprated rear anti-roll bar. The Bentley Continental Supersports Convertible also shares its ride height with the GTC Speed, sitting 10mm (0.4in) lower at the front and 15mm (0.6in) lower at the rear than the standard GTC.

The front suspension trailing lever features a new design of hydraulic bush, 33 per cent stiffer than those of GTC Speed, for improved steering response while the uprated rear anti-roll bar provides improved body control and turn-in response.

The retuned CDC system provides enhanced control of body movement to strike the optimum balance between agile handling and ride comfort during all driving manoeuvres. Agility is further sharpened by a 40:60 rear-biased torque split for the all-wheel drive system which reduces understeer during hard cornering and allows the experienced driver to modulate the car's line and balance via precise throttle control.

The 9.5Jx20-inch forged alloy wheels, shared with the Supersports Coupé, offer a weight saving of 10kg (22lb) per car, reducing unsprung and rotating mass while the open 10-spoke design offers superior brake cooling. The rear wheels have a 25mm (1 inch) greater offset resulting in a 50mm (2 inches) increase in the rear track, further benefiting handling and stability.

The lightweight wheels are fitted with 275/35 ZR 20 Pirelli Ultra-High Performance tyres, providing excellent steering response. The standard-fit tyre monitoring system allows the driver to select tyres type and speed range parameters. As well as monitoring pressures, the system warns drivers if their speed is too high for the tyre pressures or if tyre speed ratings are exceeded on winter tyres.

The Bentley Continental Supersports Convertible features an advanced electronic stability programme (ESP) that moderates intervention at low speeds, exploiting the potential of the more powerful engine and enhanced chassis, improving driver interaction and control. The new ESP also provides faster reinstatement of engine torque after intervention, giving the spirited driver greater control. The target slip is increased at greater than 90 per cent throttle to utilise all available longitudinal grip. Corner exit agility is thereby also enhanced for increased driver involvement. Together the chassis, tyre and track changes deliver improved grip, turn-in and agility.

Carbon ceramic brakes are standard fitment and provide a reduction in rotating and unsprung mass of 20kg (44lb) from the front axle, benefiting steering response, grip and ride comfort. The large diameter (420mm front, 356mm rear) lightweight discs and eight-piston calipers offer fade-resistant braking performance with minimal disc distortion under high thermal conditions. Pedal feel is also improved with shorter travel, high effectiveness and a precise pressure point.

Designing the 'extreme' Bentley convertible- where form follows function
The evolution of the Bentley Continental Supersports Convertible's design is very much a case of form following function, with new purposeful sculptural forms signalling the engineering changes beneath the skin. Key engineering-led design changes to the Supersports include:
    * Revised front air intakes and new bonnet vents to improve airflow and cooling
    * Flared rear wings to accommodate wider rear track
    * Discreet bootlid spoiler benefitting aerodynamic balance at high speeds

The increased power and torque of the W12 engine necessitated an additional 10 per cent airflow to the twin turbocharger intercoolers and cooling system. With extensive use of Computational Fluid Dynamics techniques, Bentley's designers responded with a purposeful and dramatic style, featuring large vertical intake apertures. Twin bonnet vents were added to ensure positive air extraction.

Similarly, all-new flared rear wings that accommodate the 50mm (2 inches) wider rear track are designed to emphasise the powerful stance of this ultra-high performance Convertible. The resultant Bentley Continental Supersports Convertible style combines the looks of the graceful Continental GTC with a wide, low and muscular appearance that reflects its more extreme character.

McLaren MP4-12C, 2011

McLaren MP4-12C, 2011

 

 
 The McLaren MP4-12C is revealed as the first in a range of high-performance sports cars from McLaren Automotive, the independent car division based at the McLaren Technology Centre in Woking, England. The 12C, and future models within the range, will challenge the world's best sports cars, benefiting from the expertise and virtuosity of the McLaren Group.

Twenty years of sports car design, engineering and production combined with inspirational success in Formula 1 have driven Ron Dennis, McLaren Automotive Chairman, to announce his plans for the ultimate line-up of technology-led and customer-focused performance cars for the 21st century. The rules in the sports car world are about to be re-written.

Through a rich modern history, McLaren's automotive division has already built the world's most critically acclaimed supercar, the McLaren F1 (1993-1998) and the world's best-selling luxury supercar, the Mercedes-Benz SLR McLaren (2003-2009). McLaren Automotive now looks to the future with a new range of revolutionary sports cars.

Inside out
The heart of the new car is the Carbon MonoCell. McLaren pioneered the use of carbon composite construction in the 1981 Formula 1 MP4/1 model and set a trend that all Formula 1 teams have followed. The company brought carbon fibre to road cars for the first time with the 1993 McLaren F1 and then built on this experience with a carbon fibre chassis and body on the SLR manufactured to the same exacting standards, but in higher volumes.

Carbon chassis have remained the preserve of the most expensive exotic cars; a purchase for the super-rich where costs are driven by the complexity of carbon fibre chassis design and build.

The 12C changes this by introducing the advantages of carbon composite - light weight, high strength and torsional rigidity, and longevity - to a more affordable sector through its revolutionary engineering as a one-piece moulding. Never before has a carbon fibre chassis been produced this way.

The 12C MonoCell not only brings dynamic benefits, but also offers fundamental engineering opportunities that form the basis of the car's unique character. It has been designed to allow a much narrower structure overall which in turn contributes to a more compact car that is easier to position on the road and more rewarding to drive.

Powertrain: pure McLaren
The McLaren MP4-12C is powered by a twin-turbocharged, 3.8 litre 90° V8 engine - the 'M838T'. This marks the start of a new era in 'core' segment sports cars - smaller capacity, lighter weight, higher efficiency and more economical power units. The engine has the highest specific power output in its segment which, when allied to its low weight carbon composite chassis, delivers exemplary power- and torque-to-weight ratios.

Inside: it all starts with the driver
Packaging was fundamental to the McLaren MP4-12C design challenge. Externally, the car had to be compact, yet internally it had to offer an unparalleled driver and passenger environment where comfort and driving enjoyment at all levels were not compromised.

Like the McLaren F1, the driver has controls on both sides, which allows for a rational positioning of switches:
    * Climate controls on each door console
    * Telematics on the upper centre console
    * Active Dynamics Panel on the middle centre console
    * Transmission and minor controls on the tunnel console
    * Trip computer and cruise controls on steering column

The Active Dynamics Panel provides two rotary switches and four push buttons:
    * 'Start/Stop'
    * 'Active' activates all the dynamic controls.
    * 'Winter' sets powertrain, suspension and electronic aids to maximum driver support.
    * 'Launch' initiates the launch control system.
    * The two rotary switches control 'powertrain' and 'handling', each having three position settings for normal, sport and high performance driving modes.
    * 'Powertrain' changes throttle response, gearbox strategy, shift times and impulse (how much one can feel the gearchange). The coaxial 'Manual' button controls use of manual gearbox functions.
    * 'Handling' changes stability control, steering weight, suspension firmness and roll stiffness. The coaxial 'Aero' button allows the driver to deploy the airbrake for increased downforce.
