BMW i8 eclectric 2011

Concept Vision Efficient Dynamics

   he Vision Efficient Dynamics concept car is a plug-in hybrid with a three cylinder turbodiesel engine.[3Additionally, there are two electric motors with 139 horsepower. It allows an acceleration to 100 km/h (62 mph) in 4.8 seconds and an electronically limited top speed of 250 km/h (160 mph)
According to BMW, the average fuel consumption in the EU test cycle (KV01) is 3.76 liters/100 kilometers, (75.1 mpg imp), and has a carbon dioxide emission rating of 99 grams per kilometer (1,3 l/100km and 33g CO2/km ; EU-PHEV ECE-R101). The estimated all-electric range is 50 km (31 mi), and the 24-litre diesel tank extends the total vehicle range to up to 700 km (430 mi).[5] The lightweight chassis is made mainly from aluminium. The windshield, top, doors and fenders are made from polycarbonate glass, with the body having a drag coefficient of 0.22.[8]

Pre-production version

The BMW i8 concept plug-in hybrid electric vehicle unveiled at the 2011 Frankfurt Motor Show has a 7.2 kWh lithium-ion battery pack that allows an all-electric range of 35 km (22 mi). Its top speed is electronically limited to 250 km/h (160 mph) and is expected to go from 0 to 100 kph (0 to 60 mph) in 4.6 seconds. Under normal driving conditions the i8 is expected to deliver 80 mpg-US (2.9 L/100 km; 96 mpg-imp) under the European cycle. A full charge of the battery will take less than 2 hours using 220V.
The i8 combines the electric drive system of the BMW i3, with a 96 kW (129 hp) electric motor located in the front axle powering the front wheels and at the rear is a turbocharged 1.5-liter 3-cylinder gasoline engine producing 164 kW (220 hp) and 300 Nm (221 lb-ft) of torque. The result is a combined output of 260 kW (349 hp). All four wheels provide regenerative braking. The location of the battery pack in the energy tunnel gives the vehicle a low centre of gravity, enhancing its dynamics. Together with the positioning of the motor and engine over the axles, the result is an optimum 50/50 weight distribution.

Ferrari Enzo

The Enzo, named after the founder, was established to commemorate Ferrari's first formula one title of the new millennium.
The Enzo was designed by Ken Okuyama, the Japanese former Pininfarina head designer, and initially announced at the 2002 Paris Motor Show with a limited production run of 349 and at US $659,330. The company sent invitations to existing customers, specifically, those who had previously bought the F40 and F50. All 349 cars were sold in this way before production began. Later, after numerous requests, Ferrari decided to build 50 more Enzos, bringing the total to 399. Before being unveiled at the Paris Motor show, the Enzo (that was used in the show) was flown from Italy to California to be filmed in Charlie's Angels: Full Throttle. It was driven on a beach by actress Demi Moore. After filming was complete, the Enzo was flown to France to be in the Motor Show.[3] Enzos are listed as being built in 2003. In 2003 an Enzo Ferrari delivered to Houston, Texas attorney Joe D. Jamail, Jr. was involved in a driving mishap and was totally consumed by fire. Ferrari made an additional vehicle for Mr. Jamail that carried the same serial number as the destroyed car. This kept the number of Enzo Ferraris at 400.
The Enzo Ferrari typically trades above $1,000,000 (£800,000) at auction.[4]
Three prototype "mules" were built, M1, M2, and M3. Each was bodied to look like a 348, even though the mules were built in 2000. The third mule was offered for auction alongside the 400th Enzo in June, 2005, bringing €195,500 (US$236,300).[5]


The Enzo is a mid-engined car with a 43.9/56.1 front/rear weight distribution. The engine is Ferrari's F140 65° V12 with 4 valves per cylinder, dual overhead cams and variable valve timing. Bosch Motronic ME7 fuel injection is used and the engine is naturally aspirated. It displaces 5998 cc (366 in³) and produces 660 PS (485 kW; 651 hp) at 7800 rpm and 657 N·m (485 lb·ft) at 5500 rpm.[6] The redline is 8000 rpm.[7]

[edit] Chassis

The Enzo has a semi-automatic transmission (also known as the F1 gearbox) using paddles to control an automated shifting and clutch mechanism, with LED lights on the steering wheel telling the driver when to change gears. The gearbox has a shift time of just 150 milliseconds. The transmission was a first generation "clutchless" design from the late 1990s, and there have been complaints about its abrupt shifting.[6][8]
The Enzo Ferrari has 4 wheel independent suspension with push-rod actuated shock absorbers which can be adjusted from the cabin, complemented with anti-roll bars at the front and rear.[9]
The Enzo uses 19-inch (483 mm) wheels and has 15-inch (381 mm) Brembo disc brakes. The wheels are held by a single lug nut and fitted with Bridgestone Potenza Scuderia RE050A tires.[10]
Gear 1 2 3 4 5 6 Final Drive
Ratio 3.15:1 2.18:1 1.57:1 1.19:1 0.94:1 0.76:1 4.1:1

[edit] Performance

The Enzo can accelerate to 60 mph (97 km/h) in 3.14 seconds[11] and can reach 100 mph (160 km/h) in 6.6 seconds.[6] The ¼ mile (~400 m) time is 11.0 at 136 mph (219 km/h) and the top speed has been recorded to be as high as 350 kilometres per hour (220 mph).[12] It is rated at 12 miles per US gallon (20 L/100 km; 14 mpg-imp) in the city and 18 miles per US gallon (13 L/100 km; 22 mpg-imp) on the highway.
Despite the Enzo's extraordinary performance and price, the Ferrari 430 Scuderia (an improved version of Ferrari's standard F430 production car) is capable of lapping the Ferrari test track just as quickly as the Enzo.[13]
Evo magazine tested the Enzo on the famed Nordschleife Circuit and ran a 7:25.21 lap time. The Enzo in the test had a broken electronic damper.

[edit] Accolades

In 2004, American magazine Sports Car International named the Enzo Ferrari number three on their list of Top Sports Cars of the 2000s. American magazine Motor Trend Classic named the Enzo as number four in their list of the ten "Greatest Ferraris of all time".
However, the Enzo was described as one of the "Fifty Ugliest Cars of the Past 50 Years", as Bloomberg Businessweek cited its superfluous curves and angles as too flashy, particularly the V-shaped hood, scooped-out doors, and bulbous windshield.[14]

Bugatti Veyron Grand Sport


 Bugatti Veyron Grand Sport LOr Blanc

With the partnership between Bugatti and the Königliche Porzellan-Manufatur Berlin (KPM) the renowned manufacturer emphasizes the ability in creating pieces of automotive art. The "L'Or Blanc" celebrates its world premiere with an exclusive unveiling ceremony on June 30, 2011 at the KPM workshops in Berlin. This unique version of a Bugatti Veyron Grand Sport is the world's first motor car to wear the finest porcelain on its body, as well as in its cabin. It captivates with an abstract exterior design.
The security officer nods, the door opens. Amidst pure white walls bright spotlights illuminate a Bugatti Grand Sport that is placed in the center of the spacious room. We have entered the hidden world of the Bugatti Design Studio. The team around Bugatti's Head of Design Achim Anscheidt works in a quiet and focused atmosphere as they walk around their latest object of desire. Several times they stop, take a step to the left and to the right; they bend down and up again, looking intensely at the Grand Sport from different angles. They analyse the reflections of light on the car's body before they step back for a moment to get an overall impression of their work. Thin blue lines flow over the bright white exterior of the fastest convertible in the world. It feels like visiting the atelier of an American pop-art artist.
The creation bears the name "L'Or Blanc." It represents an automobile that redefines the art of design. If you look at it through the eyes of a designer, you will recognize that it is the reflection of the studio lights on the body that attracts their interest. Positioned beneath a special light, the car is set in an ideal environment that provides an excellent image of the reflections. The studio light is reflected on the invisible edges between the body shapes of the Grand Sport. In numerous stages each reflection line is translated by Bugatti's designers onto the car body that has been pre-painted in a vibrant white tone. They use a precision tape made of Japanese soft tissue that can be easily torn off by hand. It adheres perfectly to sulphur-containing plasticine. By stretching them to a certain degree, these tapes are "lined" in pieces up to five meters long across the whole exterior of the car.

If the line does not fully meet the intention of the designers, they place a correction tape above the original line. This process is repeated until the final line has the right tension and character. Between the styling steps, the team looks at the car from a distance to evaluate the relation of the stripes to the white spaces. This is also the best way to ensure that lines flow from one side of the body across the roof and the rear to the opposite side. Even the smallest imperfections are being revised meticulously, as the final target is to achieve unrivalled perfection. Finally, the lines stretch across the perfectly shaped Bugatti like a grid of light reflections. Over the course of several weeks, the team of designers develop the final composition of dynamic bends and delicate lines that run over the automotive piece of art like the serpentines of the Italian Stelvio Pass.
"The 'L'Or Blanc' is evidence of the capabilities of the craftsmen at both brands. The distinctive structure of lines does not only mirror the elaborate hand painting on porcelain but also the process of modelling in automotive design," says Achim Anscheidt.
In the next step, Bugatti's paint specialists dedicate themselves to the further completion of the masterpiece. Over the course of three weeks, each millimeter of the marked lines are being filled by hand with the characteristic blue color. In addition, the whole body receives five layers of clear lacquer. A varying and powerful gradient of the two colors is generated because the team had used a combination of tapes with different widths. While the blue lines dominate over the white spaces in the lower section of the convertible, the relation of colors inverts on the way to the roof so that the intense white appears even stronger. Twelve elements, made of finest porcelain at the Berlin based manufactory, complete the aesthetic approach of this special Grand Sport.
Let us change the location and visit the workshops of the Königliche Porzellan-Manufaktur in the heart of Berlin. Following a tradition of around 250 years, at this location more than 170 craftsmen and specialists produce precious items, as today's expression of porcelain art. Hand-made plaster moulds are needed to craft the unique porcelain elements that appear in the exterior and interior of the Bugatti Veyron Grand Sport "L'Or Blanc", and with a tremendous attention to detail, each mould is created and optimized in a several-week-long process at the research and development department. The team has to run a number of dedicated tests with the raw material to check the impact of the natural shrinkage of around 16 percent during firing and drying. Finally, the porcelain elements fit seamlessly to the Bugatti components.
"Porcelain is one of the strongest materials but the grade of quality depends significantly on the excellence of the manufacturing process. We had to assure that the inlays perfectly fit to the filler caps, it has been a challenge for us to exactly calculate the shrinkage of porcelain," explains Thomas Wenzel, Head of Design at KPM.
The Bugatti Veyron Grand Sport "L'Or Blanc" is the world's first automobile to be equipped with porcelain, and the development team invested a lot of effort to guarantee that each item is capable of performing in every driving situation in the most powerful car on the market. Before their application to the car, the porcelain elements were extensively examined in regard to automotive safety and quality to optimally protect the passengers in case of an accident.
As part of the exterior design, porcelain is used for the inlays of the centre wheel badges, the fuel filler cap and the oil filler cap as well as the signature "EB" badge at the rear. Their shiny white surface blends in with the brilliant bright finish of the paint suggesting that the car would be coated with a thin layer of porcelain, too.
"At first, it seems to be an unusual idea to use porcelain in a car, especially in the world's fastest convertible," comments Dr. Stefan Brungs, Director of Sales and Marketing at Bugatti Automobiles. "But this is what Bugatti stands for: the realization of exceptional ideas whilst striving for the utmost in quality and aesthetics. This allows us to continue Ettore Bugatti's heritage, who himself loved to experiment with new materials."
Besides the signed porcelain inlays on the sides of the centre console, an intarsia made of finest porcelain is fixed to the rear panel between the seats. Similar to the exterior porcelain elements this item carries the relief of the famous elephant in an upright standing position that has been created by sculptor Rembrandt Bugatti. His brother Ettore had used the original draft to cast the radiator mascot for the Bugatti Royale. This elephant is a synonym for the brand still today. Embedded in the top of the centre console, there is a fine porcelain dish with edges finished in an exclusive diamond polishing - a technique that has been applied by the Königliche Porzellan-Manufaktur Berlin for the very first time. The precious dish can be removed and is part of a picnic set that was exclusively designed by KPM for the Bugatti car.
"The impulse for that partnership came from Rembrandt Bugatti's renowned elephant," tells Jörg Woltmann, owner of the Königliche Porzellan-Manufaktur Berlin (KPM) and car aficionado. "At the beginning, we wanted to integrate the sculpture in our product range, then we thought about the potential for a comprehensive service and finally the synthesis of ideas led us to this outstanding Grand Sport." Woltmann is enthusiastic about the "L'Or Blanc". "A number of superlatives are associated with porcelain from the Königliche Porzellan-Manufaktur Berlin: one says it has the most beautiful shapes and decors, it has the hardest weight and the whitest tone. Now, it is also the fastest porcelain."
The Bugatti Veyron Grand Sport "L'Or Blanc" presented in Berlin, is a one-of-a-kind creation. Nevertheless, the partnership is supposed to be continued, and Bugatti's designers received a lot of inspiration from porcelain painting offering a variety of new opportunities for the design. The price of the Bugatti L'Or Blanc is 1.65 million EUR.
