These spy shots showing Porsche鈥檚 work on a hardcore version of the 718 Cayman, which is either going to replace the GT4 or is aiming to adopt the more provocative GT4 RS name tag. The upcoming 718 Cayman range will not use a turbocharged flat-four but instead will stick to naturally aspirated six-cylinder goodness. The original Cayman GT4 was propelled by a 911-sourced 3.8-litre flat-six unit and Porsche is probably going to up the ante with a detuned version of the 4.0-litre unit found in the new 911 GT3. The spy shots show us an early prototype doing some laps at the Nurburgring, probably testing new suspension parts and an exhaust system that鈥檚 not that well fitted, indicating at a new engine providing the power. With the previous Cayman GT4 getting 385 hp, it鈥檚 safe to expect over 400 hp from the new version. One other thing that can鈥檛 go unnoticed is the wheel arches that are filled with foam, making the car look wider.
The concept also incorporates Peugeot鈥檚 next-generation Hybrid4 powertrain, which develops a total of 335bhp through the combination of a 1.6-litre four-cylinder petrol engine and a rear axle-mounted electric motor. Rumours abound that BMW will preview a new flagship model with a 9-Series concept at the Beijing show. Nothing official has been confirmed yet, but according to reports it鈥檒l be a more refined version of the next 7-Series, offering more space and tech in a bid to rival the Mercedes S-Class. Technical details are currently few and far between ahead of its Beijing debut, but as you can see the wide front grille, slim headlights and converging creases on the flanks echo the GLA-class. This picture also shows a drastically plunging roofline, underlining the coupe-SUV fusion alluded to by the concept鈥檚 name. The Infiniti Q50 Eau Rouge concept has featured on the Infiniti stand at a number of recent motor shows, and each time it seems to take yet another step towards reality.
For Beijing there鈥檒l be a film featuring four-time Formula 1 world champion Sebastian Vettel testing the Eau Rouge in his capacity as Infiniti鈥檚 Director of Performance. An inside source has claimed we鈥檒l also see a stripped-out version of the range-topping Golf at Beijing, expected to be called the R Evo. The superhot-hatch will use drastic weight saving measures to slash the standard R鈥檚 1,476kg kerbweight. Features will include lower suspension, a massive rear spoiler, and a roll cage in place of the rear seats. When combined with a slightly tuned version of the Golf R鈥檚 2.0-litre turbocharged four-cylinder engine, which currently generated 296bhp and 380Nm of torque. A four-wheel drive Golf R Evo fitted with VW鈥檚 six-speed DSG should manage 0-62mph in around 4.6 seconds. We expect it to presented as a concept initially, with a production model launched early next year for a little over 拢30,000. If a Chinese debut for the new Huracan wasn鈥檛 enough, Lamborghini is also planning on showing off an Aventador Nazionale at Beijing. According to a statement from the Italian manufacturer, the special edition is a 鈥渉ighly exclusive and appealing configuration鈥?created by Ad Personam, Lamborghini鈥檚 personalisation programme that allows customers to design their own made-to-order supercar.
Although the Porsche Carrera GT was initially released as 2004 model, a number of other improvements were carried out the following year that transformed it into a super car. The changes were essentially to make it more adapted for street use. A glass screen was placed between its supplemental bar hoops, and the height of the seats were adjusted. Given its sleek appearance, it is quite easy to spot a Porsche Carrera GT in the street. There are removable panels that give additional protection against poor weather conditions, which can be kept in the trunk until the need arises. This car has a V10 engine that produces 605 horsepower, with an engine capacity of 5.7 litres. Think about it; the power of 605 horses under the hood of your car. In addition a 5700cc engine; this car is all about power and not about fuel economy. The aerodynamic suspension package, which is achieved through sophisticated design, makes it safe to drive the Porsche Carrera GT at speeds of up to 205 miles per hour.
It has been said before that if you are going to design a fast car, then you also have to design the safety that goes with a fast car. For example, the braking system, the handling and stability and the like. The 2005 Porsche Carrera GT uses ceramic brakes, made of 15-inch ventilated discs as well as 6-piston calipers, making it possible to stop the car almost as fast as it accelerates. Several parts of this 'street racecar' are made of lightweight materials like magnesium. Some of these parts include the sport seats and the wheels. Such constructions are helpful in achieving high speeds. For example, it takes just 3.9 seconds for the car to go from 0 to 62 mph and it reaches 125 mph in under 10 seconds. These achievements are also made possible by the car's 5.5 litre engine that has enlarged bores, which enable the displacement of 5.7 litres. The car has four valves-per-cylinder head, V angle of 68 degrees, and low centre of gravity. A low centre of gravity means that the weight of the car is lower to the ground. For example a high sided vehicle like a semi, when it is heavily loaded could topple over in high wind because it has a high centre of gravity. However, the same semi, with no load has a low centre of gravity because most of the weight is in the wheels and the axles, which are nearer the ground. In short a low centre of gravity means more stability. With all its power, the engine's weight is just 472 pounds, having been made of various light alloys.
