2007 Wiesmann GT




Completed just in time for the start of the IAA: the Wiesmann GT with the model name of MF 5 and a 10-cylinder motor. Hiding behind this unpretentious name is the most exciting sports car ever to be presented by Wiesmann to the public.

It is a perfect blend of the corporate philosophy's contents, which is a combination of beautiful body shapes and state-of-the-art technology. The appearance of this super sports car alone would clearly signal the arrival of something extraordinary: a very low and cowered-down body in combination with wide base tyres stand for abounding power and a highly racy vehicle to be expected.

Wiesmann fulfils the desire of many a GT enthousiast, who had welcome the successful expansion of the Wiesmann model portfolio, and who, at the same time, had still wanted for the engine to become even racier.

Dipl.-Kfm. Friedhelm Wiesmann (business graduate), spokesman of the board, explains: "Our intention is to meet these demands with the GT MF 5. This new sports car tops off our porfolio of models, setting the new benchmark when it comes to the Wiesmann sports cars' driving performance - which is rather impressive anyhow."

Dipl.-Ing. Martin Wiesmann (graduate engineer), managing director in charge of development and production, says: "Compared to the normal GT, it is already the outer appearance of the MF 5 that would be outstanding: both a wing as well as a diffusor generate the necessary rear-suspension drive line, thus ensuring an excellent stability especially for those high-speed moments. A lot of effort went into the development of a high-performance chassis to make sure the MF 5 driver will enjoy the ride and yet will at all times be safe no matter what."

The drive system of this super sports car comprises a 12:1 compacted V 10-cylinder front-mounted mid-engine with a cubic capacity of 5 litres boasting 507 HP which are generated by 7,750 crankshaft rotations. A maximum torque of 520 Nm ensures a powerful drive at all speeds and driving fun at its best.

GT experts will immediately notice the lower total height (- 5 cm), the slight increase in width (+ 9,6 cm), and the increase in total length by 8 cm to 4.3 m compared to the MF 4 with a correspondingly bigger track gauge of + 10 cm (front) and + 9.8 cm (rear). These details are crucial for its very low centre of gravity and hence its good roadability.

In spite of all its safety features, the vehicle's bigger size, the engine's high capacity, and the corresponding sequential 7-speed transmission system (in connection with a variable differential lock) account for a modest increase in weight of only 100 kg compared to the MF 4. The resulting driving performance is beyond each doubt: the acceleration time of 0 - 100 km/h is 3.9 seconds, and the power to weight ratio amounts to a sensational 2.7 kg/HP. With this value the MF 5 ranks among the top class of the sportsters league.

In order to be able to control such a powerful vehicle, both its driver as well as its fellow passenger need to be in close contact with it. The GT MF 5 therefore comes with especially designed bucket seats with an excellent lateral support, which by request may be adjusted to the driver's and fellow passenger's body contours. They give the necessary support, for the passengers to have a firm grasp in view of the great acceleration forces that may develop, and to be able to fully enjoy the driving performance. Special carbon seats are also available by request.

The passengers' safety is ensured by energy absorbing car body parts, by a stiff aluminium monocoque including a side-collision protection structure, and by the serial ABS combined with a dynamic stability control system DSC.

The months following the world premiere will be reserved for fine tuning and long-term as well as endurance testing, in order to fulfil all requirements of those already highly interested in Wiesmann's newest super sports car.

bentley continental gt


The Bentley Continental GT is a two-door 'two plus two' grand touring coupé released in 2003, replacing the previous Rolls-Royce-based Continental R and T.
A re-bodied Volkswagen Phaeton, it is equipped with a 5,998 cubic centimetres (366.0 cu in) (6.0 litre) twin-turbocharged W12 engine, which produces a DIN-rated motive power output of 560 metric horsepower (412 kW; 552 bhp) at 6,100 rpm, and torque of 650 newton metres (479 ft·lbf) at 1,600-6,100 rpm.[1] Torsen-based permanent four-wheel drive is standard.[1] It will accelerate from 0 to 100 kilometres per hour (0 to 62.1 mph) in 4.8 seconds, and go on to reach a top speed of 318 kilometres per hour (197.6 mph)
A revised Continental GT was announced for the 2011 model year. The first model, and only model announced through November 2010, is the coupe. In addition to the W12 engine that carries over from the first generation with updates, the new model will also be available with a 4.0 L V8 engine

In early 2007, a Bentley Continental GT Speed, driven by four-time World Rally Champion Juha Kankkunen, broke the World Speed Record on Ice - on the frozen Baltic Sea near Oulu, Finland. It averaged 321.6 kilometres per hour (199.83 mph) in both directions on the "flying kilometre", reaching a maximum speed of 331 km/h (205.67 mph). The previous record was 296 km/h (183.9 mph), achieved with a Bugatti EB110 Supersport. The record-breaking Bentley was largely standard except for a roll-cage, aerodynamic improvements, and low-temperature fuel and calibration.[12]
On February 15, 2011 Kankkunen broke the record again, reaching an average speed of 331 km/h (205.67 mph) in a convertible Bentley Continental Supersports. Bentley announced that a limited edition of the car would be released to celebrate the achievement.[13] On March 6, 2011 Nokian Tyres, piloting an Audi RS6, took the ice speed record in Finland, clocking a top speed of 206.05 mph (331.61 km/h) in freezing conditions.[

aston martin db9

The DB9 is the first model to be built at Aston Martin's Gaydon facility in Warwickshire, England. The moniker "DB" stems from the initials of David Brown, the owner of Aston Martin for a significant part of its history. The DB9, which was designed by Ian Callum and finished by his successor, Henrik Fisker, superseded the now-discontinued Aston Martin DB7 (also by Callum) which started production in 1994

nissan z350

                                                                                              The Nissan 350Z is a two seat sports car that was manufactured by Nissan from 2002–2009 and marks the fifth generation (codename: Z33) of Nissan's Z-car line. The 350Z entered production in late 2002 and was sold and marketed as a 2003 model. The first year there was only a coupe, as the roadster did not debut until the following year. Initially, the coupe came in base, Enthusiast, Performance, Touring and Track versions, while the roadster was limited to Enthusiast and Touring trim levels. The Track trim came with lightweight wheels and Brembo brakes, but its suspension tuning was the same as all other coupes. The Nissan 350Z has been succeeded by the 370Z for the 2009 model year.A proper sports car for the everyman. If we had just one sentence to describe the Nissan 350Z, that'd be it. While there have always been plenty of unobtainable sports cars out there to drool over, the 350Z's relatively compact dimensions, rear-wheel drive, two seats, muscular engine and sharp handling came at a price that real people could actually afford.
The Nissan 350Z represented the fifth generation of "Z" sports cars from this Japanese manufacturer. At its debut in 2003, the 350Z represented a key component of Nissan's rebirth in the North American market. For much of the late '90s and early new millennium, Nissan's lineup was full of lackluster cars. The Z brought back the company's spirit of fun and performance that had been missing ever since the discontinuation of the previous 300ZX.
The 350Z coupe was replaced by the 370Z coupe for 2009, while the 350Z roadster lived on before following suit the following year. In coupe or drop-top form, the 350Z was quite popular so finding a nice example on the used car market should be relatively easy. That said, keen shoppers will want to pay close attention to the car's changes and updates that were made through the years.

lamborghini aventador

The Italian super car maker has finally unveiled the Lamborghini Aventador LP 700-4 through photos and and new details which also include pricing information.

Most of the technical details have been available for some time now, but lets just do a recap. Power is extracted from a 6.5-litre V12 which outputs 700 horses (515 kW) and 690 Nm (509 lb-ft) of torque via a dually synchronized ISR 7-speed independent shift rod transmission from Graziano.

Like previous Lamborghinis, the Aventador name was chosen for its symbolic connection to the world of fighting bulls, sharing a name with the legendary Aventador, a trophy-winning bull in the world of Spanish bullfighting. Bred by the sons of Don Celestino Cuadri Vides, the bull that bore the number 32 took part in a notably spirited, bloody and violent battle with a torero in the town of Zaragoza, Spain that earned him the “Trofeo de la Peña La Madroñera" in 1993.[3][9]
Production will be limited to 4000 units (4099 MurciĂ©lagos have been built). The moulds used to make the carbon-fibre monocoque are expected to last 500 units each and only 8 have been made.[10] Lamborghini says that the Aventador is two generations ahead of anything else on sale, using Formula One-style suspension and a lightweight carbon fibre monocoque.[11] Stylistically, the Aventador represents an evolution of its predecessor, the MurciĂ©lago. The car's shape also borrows heavily from Lamborghini's limited-edition ReventĂłn and their Estoque concept car

ferrari f430 maranello

 .To an automotive journalist, Maranello in October beats the stuffing out of Paris in the spring. Especially when the occasion is the first chance to drive the Ferrari F430 — a 483-bhp, Ford GT-eating caricature of the 360 Modena with near Enzo-level performance. For a full road test of the car, see our January 2005 issue. But for a small glimpse of what goes on behind the scenes at Ferrari’s fabled birthplace, and a closer look at some of the technicalities that make this new Ferrari special, read on.
Compact, dohc 4-valve-per-cylinder heads. Intake ports, whose shape has profited from Formula 1 development, are fully machined and then hand-polished.
F430 and F1 undertrays shows the lengths that Ferrari has gone toward generating downforce in their road cars. Blue shading indicates areas of greatest negative pressure.
Carbon-ceramic brake rotors, impressive but cost $14,300 extra! Double-wishbone suspension has forged aluminum links and shocks with variable damping.
This cutaway transaxle shows the clutch pack of Ferrari's E-Diff, a hydraulically modulated, electronically controlled limited slip with a wide range of adjustability.
Time to drive! Both Ferraris and journalists assemble in the courtyard adjacent to the company-owned Fiorano circuit. This will certainly be a good day.
Decisions, decisions: silver, red or yellow? Both photographer Stephane Foulon and I opted for the last, but there is no wrong choice here for the F430.
The F430’s more powerful engine needs more air, and the coolant radiators get an extra shot through front intakes that recall the “shark nose” Formula 1 Ferraris of the early 1960s.

alfa romeo brera

The Alfa Romeo Brera is a sports car produced by the Italian automaker Alfa Romeo between 2005 and 2010.[3] The Spider roadster was produced between 2006 to 2010. Both cars were manufactured by Pininfarina. Only 12,488 units of Spider and 21,786 units of Brera were built.[4] Production of both models stopped in November 2010.[5]The Alfa Romeo Brera was introduced in production form at the 2005 Geneva Motor Show. It maintained the original's exterior appearance almost exactly but on a much smaller scale, becoming a mid-size coupe on the GM/Fiat Premium platform (shared with the Alfa Romeo 159), and designed to replace the outgoing GTV. A convertible Spider version of the Brera was also announced, to be launched shortly after the coupe and to replace the existing GTV-based Spider.

ford shelby cobra gt500

The 1965–1966 cars were the smallest and lightest of the GT 350 models. These cars are often improperly called "Cobras", which was the Ford-powered AC-based two-seat sports car also produced by Shelby American during the same period. The confusion arises from the use of the Cobra emblem, the paint scheme, and optional "Cobra" valve covers on many GT350s (part of a marketing tie-in by Shelby as well as one of his iconic symbols). All 1965–66 cars featured the K-Code 271 hp 289, modified to produce 306 hp. Marketing literature referred to this engine as the ""Cobra hi-riser" due to its high-riser intake manifold. Beginning as a stock Mustang with a 4-speed manual, the cars were shipped to Shelby American, where they received the high-riser manifolds, had their stock Ford Falcon live rear axles replaced with heavy-duty Ford Galaxie rear axles, and were given larger, metallic-lined rear drum brakes and Kelsey-Hayes front disc brakes. The 1965 G.T. 350 was truly a street-legal race car, and as such was not built for comfort or ease of driving. Even more "hairy" were the less than 30 "G.T. 350R" race-spec cars that were built specifically to race under SCCA rules. While the 1966 G.T. 350 was still an extreme and difficult car, it had some of its sharper edges smoothed out for the comfort of casual drivers (i.e back seats, different colors, automatic transmission). This trend continued every year, with the cars becoming progressively larger, heavier and more comfortable, while losing much of their competitiveness in the process. The 1969 G.T. 350's and 500's were largely styling modifications to a stock Mustang, not at all the light and harsh racers of 1965-67. By 1969 Caroll Shelby was no longer involved in the Shelby GT program, and design was done in-house by Ford. As the Shelby GT's popularity was built on its reputation as an "all-race" automobile, once word began to spread in the street that the newest Shelby's were simply Mustangs with "Shelby" badges and different trim, sales began to slip.
1965–1966 G.T. 350s were delivered from Ford's San Jose assembly plant in body in white form for modification by Carroll Shelby's operation, originally in Venice Beach and later at Los Angeles International Airport. San Jose cars carried an "R" in the Ford VIN denoting that facility.[2] The only year that Shelby Mustangs from the 1960s came from another plant was 1968, where they came from New Jersey, "T" in the VIN,[3] and were modified by A.O. Smith.
1965–66 GT 350s were very successful racers, and had many production-class victories

audi q7 v12 tdi


he World's Most Powerful Diesel Passenger Car

Audi has presented the world's first twelve-cylinder diesel engine in a series passenger car. This six-liter V12 makes its debut in the Audi Q7. It produces a colossal 500 bhp and 738 lb-ft of torque. With this engine Audi has opened a new chapter in diesel history.

The V12 TDI is reminiscent of the engine featured in the new R10 Le Mans racing car - it catapults the driving performance of the Audi Q7 into the echelons of top-class sports cars. The car sprints from 0 to 62 mph in just 5.5 seconds, and has an electronically governed top speed of 155 mph. Maximum torque is available from just 1,750 rpm. The high-tech diesel engine, with the world's first 29,000 psi Bosch Common Rail system, provides the high-performance Audi SUV with superior power reserves in any situation. The impressive sound of the new Audi is provided by the ultra-modern piezo-injection system. The V12 TDI transmits this power through a new six-speed tiptronic gearbox to the quattro permanent four-wheel drive system.

Although the V12 TDI belongs to the Audi V-engine family, this model features a special cylinder angle of 60° - perfect for this engine type. Apart from the light and highly durable crankcase, a further highlight is the new chain drive assembly. This includes the two newly developed high-pressure pumps in the common rail injection system.

Up to 29,000 psi of pressure is kept within the twelve piezo injectors - a further technological breakthrough. Both performance and efficiency are optimized by this high injection pressure, and the running smoothness also remains excellent. Exhaust emissions are also low. The twin-turbo V12 TDI conforms to the Euro 5 emissions class which should come into force in 2010. Combined fuel consumption is nearly 20 mpg. With the high-tech twelve-cylinder engine using TDI technology, the diesel pioneers at Audi have opened new horizons in motoring.

The Design

The Audi Q7 V12 TDI is impressive not only with regard to technology but also in terms of appearance. The most striking visual changes to the Audi Q7 are the underbody panels at the front and rear. The chrome-plated single-frame radiator grille evokes the tradition of the Audi S6 and S8. These two cars, with their V10 FSI engines, are the top sports models in their class. The V12 TDI features a powerful braking system which is every bit its equal.

There are currently no plans to import this engine to the North American market.Audi is proud to present a world first – the first twelve-cylinder diesel engine in a series passenger car. This six-litre V12 makes its debut in the Audi Q7. It produces a colossal 500 PS and 1,000 Nm of torque. With this engine Audi has opened a new chapter in diesel history.
The V12 TDI is reminiscent of the engine featured in the new R10 Le Mans racing car – it catapults the driving performance of the Audi Q7 into the echelons of top-class sports cars. The car sprints from 0 to 100 km/h in just 5.5 seconds, and has an electronically governed top speed of 250 km/h. Maximum torque is available from just 1,750 rpm. The high-tech diesel engine, with the world’s first 2,000 bar Bosch Common Rail system, provides the high-performance Audi SUV with superior power reserves in any situation.
