    comparisons
  • (comparison) the act of examining resemblances; "they made a comparison of noise levels"; "the fractions selected for comparison must require pupils to consider both numerator and denominator"

  • (comparison) relation based on similarities and differences

  • Comparisons is a Canadian documentary television series which aired on CBC Television from 1959 to 1963.

  • An analogy

  • The act or instance of comparing

  • The quality of being similar or equivalent





    car tyre
  • A tire (in American English) or tyre (in British English) is a ring-shaped covering that fits around a wheel rim to protect it and enable better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground.

2001 Volkswagen Nardo W12 Show Car rear right 1





The Italdesign Giugiaro study of the W12 Coupe, which is systematically oriented towards top performance and high levels of driving dynamics, is the third phase of evolution of two W12 concept cars becomes the fastest cars in the world. The W12 Syncro prototype was first unveiled at the 1997 Tokyo Motor Show, while the "Roadster", a more advanced version of the W12 Syncro, made its debut at the Volkswagen stand at the 1998 Geneva Motor Show. The final evolution of this sports car project, with its W12 engine inspired by the world of motor sports, was showed at the last Tokyo Motor Show and now is entering the decisive phase of production development. On October 2001 a prototype of Volkswagen's new W12 coupe in the final stages of development set the world speed record for distance covered in 24 hours. The long term development of this project becomes a real partnership between Volkswagen technical and Italdesign Giugiaro staff.The long and flat body of the Coupe, with the restrained styling of the rear spoiler with automatically extends as of 120 km/h, transports the timeless elegance of Volkswagen design into the dynamic sector of the ultimate sports car. Due to the monocoque construction and the location of the longitudinal engine fitted behind the passenger compartment, the front end of the vehicle could be kept extremely flat. With a length of 4.55 metres and at more than 1.92 metres wide, the design study W12 Coupe has a very impressive appearance due to its dimensions alone. This is further underlined by the height of the two-seater vehicle, just 1.1 metres. The design study has been further reflned in comparison to its two predecessors; newly designed headlights and rear lights echo even more strongly the characteristics of the future top class models from Volkswagen. One of the most famous studios in the world is responsible for the design of the vehicle: Italdesign, Giugiaro, Fabrizio Giugiaro, Styling Director,said: " this is one of the most fascinating cars in the world and for sure the fastest and most reliable never built".Smooth leather has been used for the element where the driver has direct access to the function elements - namely the steering wheel. The steering wheel itself is not perfectly round, but is rather extremely similar in form and function to the concepts used in Formula One racing. Alongside the use of leather, the aluminium elements in the interior are particularly noticeable as they have a red sheen and thus correspond to the exterior colour. Volkswagen is using a new chemical procedure to achieve the colouring and surface coating of the unpainted alloy. The layout of the instruments is classic.Two round main displays show the most important information such as speed, revs, fuel tank (100 litres) and engine temperature. A colour display in the centre of the dash panel is used to control the functions of the air conditioning, the navigation system, the on-board computer and the car telephone. Furthermore, the amount of space in the W12 Coupe is extremely comfortable. A generous and ergonomically perfect situation has been realised despite the low level of the vehicle typical of a sports car. There is no doubt - this design study is more than a show car. All the details of the W12 Coupe are fully-functional and the concepts are close to production standards.In the future, all Volkswagens in the upper and luxury classes will be equipped with the high-torque W engines. They are characterised by exceptionally low levels of vibration and the best possible acoustic qualities. They are, depending on the model in question, used as standard- in the W12 Coupe for example - or as an option. The Volkswagen brand will launch them as an eight-cylinder, as can already be seen in the Passat W8, and as a twelve-cylinder version with varying levels of output and set-ups. A 16-cylinder version has also been developed on this basis within the Volkswagen Group.The technology of the twelve cylinder engine integrated in the design study W12 Coupe: with a length of 513 millimetres, a height of 715 millimetres and a width of 710 millimetres, the engine is particularly compact. The capacity of the W12, which weighs just 239 kilograms, is 5,998 cm3. The engine, which is located between the passenger compartment and the rear axle, has an extraordinarily torsionally rigid aluminium crankcase with wear-resistant cylinder sleeves.The enormous power of the engine is transferred to the rear axle via a sequential and thus very fast shiRing six-speed gearbox located behind the engine. This is very favourable for a classic sports car layout. The contact to the road is made via specially developed 19" magnesium wheels with 255/35 ZR front tyres and 275/40 ZR rear tyres. The sophisticated front and rear axle with double wishbone, numerous electronics modules, an ideal weight distribution of nearly 50:50 and an extended wheelbase of 2. 63 metres ensure that the W12 Coupe is both fast and sa











Silcantar Laurevorn




Silcantar Laurevorn





Silcantar Laurevorn is a subcompact front-mid-engine grand touring roadster. No, that's not an oxymoron, not anymore, anyways. It is powered by a Silcantar V8 engine, the same one as in the Valthalion, mounted behind the front axle. However, unlike the Valthalion, its wheelbase is only about 3 times longer than the diameter of its tires. This almost square wheelbase, combined with low center of gravity, low mass, and symmetrical four-wheel steering, makes for very unique handling characteristics. Because of its high power/mass ratio, it is one of the fastest-accelerating cars in the world, accelerating from zero to 100 km/h in under four seconds (for comparison, the Bugatti Veyron, with twice as much engine, does it in 2.5s). Due to the fact that it is a convertible and lacks fenders and therefore has less-than-stellar aerodynamics, its top speed doesn't compete well with supercars. Its short wheelbase, however, makes it lighter and more rigid than the average convertible.

Laurevorn, like Valthalion, features Silcantar's signature lack of fenders (Now I have an excuse to be lazy). The seats are located just in front the rear wheels, giving the passengers enough leg room to make any NBA star comfortable for hours-long drives.

Features:
V8 engine
4 wheel drive
Symmetrical 4 wheel steering (front and rear wheels steer the same amount)
4 wheel independent double wishbone suspension
4 speed manual gearbox
(I suppose that makes it 4x4x4x4, right?)

By far the most challenging part of building Laurevorn was getting the engine and the transmission between the axles, even though symmetrical 4-wheel steering eliminates the need for a center differential. The transmission is only 8 studs long (the minimum in general and the maximum for this car), with the crankshaft running right through the middle of it. The drive shaft for the front wheels runs through the passenger's right armrest. Mostly by luck and a little bit of skill, it ended up quite elegant, though.
In addition, I have also perfected the Valthalion suspension. Laurevorn has the same low ground clearance, but the suspension is firmer and the shocks no longer get in the way of the steering linkages, which slightly decreased the tightness of Valthalion's turns.

The lines of gray bricks in the picture below are each 32 studs long (2 16-stud Technic bricks) As you can see, both the wheelbase and the width are slightly less than 32 studs.
