2012 Lexus LFA







There’s something slightly weird about this scene. We are about to drive the daunting 12.9-mile Nürburgring Nordschleife track in Germany. In a Lexus. Okay, it’s the exotic LFA, a Ferrari-fighting supercar that will cost about $350,000. But the company built its reputation on smooth, refined, and perfectly nerve-calming cars, so why does the LFA exist? In what parallel universe is this thing remotely Lexus-like?
Lexus claims multiple justifications for the LFA program. The car, it says, casts a halo over the Lexus F line of performance machines. It’s also a way for Toyota to explore new technologies, particularly carbon-fiber construction. And since Lexus says it will be selective about whom it will sell to—car collectors and high-profile individuals who use the car rather than park it—the LFA should raise the cachet of the brand as a whole.
For all that marketing happy-talk, the 2012 LFA is a serious outlier in the Lexus lineup and has had a convoluted gestation. The program started in 2000, and Lexus showed the first concept car at the Detroit auto show in 2005. Next, a convertible version appeared at Detroit in 2008, though it has since been canceled. In the interim, LFA prototypes were spotted testing at the Nordschleife, and further, two race-prepared cars entered the 24-hour race at the Nürburgring in 2008 and 2009. But until now, the company hasn’t said anything about production intent. Lexus is finally ready to admit that a mere 500 will be made, with production starting in December 2010.
Although the car is extravagantly expensive, Lexus says it will lose money on every one. We believe it. The last car that incorporated a similar level of technology, performance, and exclusivity was the $650,000 Ferrari Enzo. At $350,000, the LFA begins to look like something of a bargain. The LFA is an exotic, two-place, front-engine, rear-wheel-drive coupe. The chassis and body are made largely of carbon-fiber composite, just like those of an Enzo or a Mercedes SLR McLaren. Per Lexus’s scales, the car weighs 3263 pounds—less than a Corvette ZR1.
The engine is a 4.8-liter V-10 codeveloped with Yamaha. It’s a compact unit that makes 553 horsepower at 8700 rpm and revs to a giddy 9000 rpm. Maximum torque of 354 pound-feet peaks at 6800 rpm, with 90 percent available between 3700 and 9000 revs.
The rear-mounted, six-speed automated manual transaxle incorporates a Torsen limited-slip differential. Control arms comprise the front suspension, with a multilink arrangement at the back. To keep weight down, the suspension pieces and the remote-reservoir monotube KYB dampers are aluminum.
The Brembo carbon-ceramic brake setup consists of discs 15.4 inches in diameter and six-piston monoblock calipers up front, with 14.2-inch discs and four-piston calipers at the back. Forged aluminum 20-inch BBS wheels sit inside bespoke 265/35 front and 305/30 rear Bridgestone Potenza tires. There are four driving modes: automatic, normal, wet, and sport; the driver can also select manual shift speeds. In sport mode, the stability-control system allows for greater amounts of yaw, but the system can be switched off completely.
When it comes to the styling, there’s a definite Japanese aesthetic, what with all the sharp edges and matte-black vents. But it’s not a head turner like the Enzo or even a Lamborghini Gallardo. We definitely wouldn’t order one in matte black—one of 30 available colors—because it looks like someone forgot to paint it properly.
But there is function underpinning the somewhat sedate form. According to chief engineer Haruhiko Tanahashi, an advantage of using carbon fiber for the bodywork is that it’s possible to make very sharp edges and cutoffs that improve aerodynamic performance. The LFA has a reasonably low coefficient of drag (0.31), and Tanahashi says that the car produces more downforce than any of its competitors. Even the inside edges of the door mirrors are shaped to guide air into scoops over the rear fenders that feed the rear-mounted radiators. A large rear wing incorporating a Gurney flap pops up at speeds above 50 mph.
The interior is restrained but tasteful. The car we drove had a mixture of supple leather, carbon fiber, Alcantara, and “satin metal” adorning the cockpit. Lexus will offer seat coverings in 12 shades of leather or 10 alternate hues of Alcantara, with three color choices for the Alcantara headliner. “Roomy” describes the cabin, although luggage space is minimal. The supportive bucket seats have eight-way power adjustments, and the driving position is superb. The minor controls are as easy to find and use as in a standard Lexus sedan, and the LFA even has the same mouse-style operation for its multi­function center-console screen as in an RX350 sport-ute.

Dodge Viper




The Dodge Viper is one of the first V10-powered cars in the world, made by the Dodge division of Chrysler. Production of the two seat sports car began at New Mack Assembly in 1991 and moved to its current home at Conner Avenue Assembly in October 1995. The car, and numerous variations, has made many appearances in TV shows, video games, movies, and music videos[citation needed]. Although Chrysler considered ending production because of financial problems,[1][2] chief executive Sergio Marchionne announced and showed on September 14, 2010 a redesign of the Viper for 2012.[3]
The Viper was conceived as a historical take on the classic American sports car. The iconic AC Cobra was a source of inspiration, and the final version of the Viper bears this out with its powerful engine, minimalist straightforward design, muscular and aggressive styling, and high performances. Some saw claims to kinship with the Cobra as a marketing exercise, ignoring that Carroll Shelby was heavily involved in the initial design of the Viper, and subsequent design of the Viper GTS coupe. Notably, the later (1996 through 2002) Viper GTS coupe took a few design cues from the Pete Brock designed Shelby Cobra Daytona Coupe. Though the proportions seem similar at first glance, the designs are quite unique. Carroll Shelby was key in the development of the RT/10 as well as having a hand in the development of the GTS (Viper Coupe) model.
The Viper was initially conceived in late 1988 at Chrysler's Advanced Design Studios. The following February, Chrysler president Bob Lutz suggested to Tom Gale at Chrysler Design that the company should consider producing a modern Cobra, and a clay model was presented to Lutz a few months later. Produced in sheet metal by Metalcrafters,[4] the car appeared as a concept at the North American International Auto Show in 1989. Public reaction was so enthusiastic, that chief engineer Roy Sjoberg was directed to develop it as a standard production vehicle.
Sjoberg selected 85 engineers to be "Team Viper," with development beginning in March 1989. The team asked the then-Chrysler subsidiary Lamborghini to cast some prototype aluminum blocks based on Dodge's V10 truck engine[citation needed] for sports car use in May. The production body was completed in the fall, with a chassis prototype running in December. Though a V8 was first used in the test mule, the V10, which the production car was meant to use, was ready in February 1990.
Official approval from Chrysler chairman Lee Iacocca came in May 1990. One year later, Carroll Shelby piloted a pre-production car as the pace vehicle in the Indianapolis 500 race. In November 1991, the car was released to reviewers with first retail shipments beginning in January 1992.
SRT-10 serves as the next chapter for the Viper. The very first Viper was previewed at the North American International Auto show in 1989. The concept had a simple design that was reminiscent of the Ford Cobra: gobs of power up front, two seats with power delivery to two huge rear wheels. With a massive overall response, Dodge was motivated to put the design into production by 1992. In 1996 the GTS coupe version followed.
In 2003, an all-new Viper is being offered by DaimlerChrysler.
Building on the last platform, the new SRT-10 improves every facet of the race-bred version that came before it. Whats new? As you would expect, more power, less weight, bigger brakes and more interior comfort. What didn't show up was cup holders or cruise control!
The all aluminum V10 engine has a slight increase in capacity to 505 cu. in. This pushes the power output to 500 horsepower and 525 lb.ft. of torque. DaimlerChrysler states that the engine architecture remains much the same as the previous Viper. Minor improvements include a refined cyinder head, valvetrain and a larger cooling system.
DamlierChysler have taken 100 pounds off the car by updating several components: the now-standard run-flat tires eliminated the need for the spare tire, a new magnesium dash replaces the old one and the fenders are now resin injection molded (RIM).

Porsche Carrera GT







The Porsche Carrera GT (Project Code 980) is a mid-engine sports car from Porsche in Leipzig, Made in Germany.
The development of the Porsche Carrera GT can return back to their predecessors, the 911 GT1 and LMP1-98 racing cars. Due in part to the FIA and ACO rule changes in 1998, both designs had ended. Porsche had planned at the time on a new Le Mans prototype in 1999. The car was originally to use a turbo flat-6, but was later revised to use a new V10 engine, pushing the project back to the planned completion in 2000. The V10 was a unit secretly built by Porsche for the Footwork Formula One team in 1992 but later shelved. The engine was developed for the Le Mans prototype and increased in size risen 5.7 liters.
Unfortunately, the project was done in two days of testing for the first car in mid-1999, due primarily to do the Porsche Cayenne SUV with involvement from Volkswagen and Audi build and require engineering skills are thus pulled from the motorsports division. It was also speculated that VW-Audi chairman Ferdinand Piech Audi’s new Le Mans Prototype, the Audi R8 is not the competition from Porsche in 2004 was given.
Porsche Carrera GT did keep the project alive by using the 5.5 L V10 from the prototype in a concept car at the 2000 Geneva Motor Show show, especially in an attempt to draw attention to their ad. Surprising interest in the vehicle and an influx of revenue from the Cayenne decide provided helped Porsche to produce the car, and the development began with a street-legal version that would be produced in small numbers at Porsche’s new plant in Leipzig. Porsche started a production of the Carrera GT in the 2004 run, sending the units with a MSRP of $ 440,000 USD and a dealer invoice price of approximately $ 414,800 USD. In addition, the delivery charge could be as much as $ 5,000. The first Carrera GT went on sale in the U.S. on 31 January 2004.
The Carrera GT is powered by a 5.7 litre V10 engine producing 612 PS (450 kW; 604 hp) ,[5] whereas the original concept car featured a 5.5 litre version rated at 558 hp (416 kW). Porsche claims it will accelerate from 0 to 100 km/h (62.1 mph) in 3.9 seconds and has a maximum speed of 330 km/h (205 mph),[3] although road tests indicated that in reality the car can accelerate from 0-60 mph (97 km/h) in 3.5 seconds[5] and 0-100 mph (160 km/h) in 6.8[5] seconds. The Carrera GT has a basic five colour paint scheme which includes Guards Red, Fayence Yellow, Basalt Black, GT Silver and Seal Grey. Custom colours were also available from the factory. A traditional six-speed manual transmission is the only available transmission. Attached to this gearbox is a beechwood gearknob which pays homage to the wooden gearknob used in the Porsche 917 Le Mans racers. In its second year of production, a limited edition carbon fibre knob was also made available.
The Carrera GT has large side inlets and air dams that help cool the large V10 engine framed by the carbon fibre rear bonnet. Fitted with Porsche's latest Carbon fibre-reinforced Silicon Carbide (C/SiC) ceramic composite brake system, the 15-inch (380 mm) SGL Carbon disc brakes make an impressive appearance underneath the 19 inch front and 20 inch rear wheels. Similar to other Porsche models, such as the 911, the GT includes an automated rear wing spoiler which deploys above 70 mph (110 km/h).
The interior is fitted with soft leather. Bose audio system and navigation systems are available as options. In typical Porsche fashion, the ignition is to the left of the steering wheel. This placement dates back to the early days of Le Mans racing when drivers were required to make a running start, hop into their cars, start them and begin the race. The placement of the ignition enabled the driver to start the car with his left hand and put it in gear with his right.

Jaguar XJ220



Jaguar XJ220 is a mid-engined supercar produced by Jaguar in collaboration with Tom Walkinshaw Racing as a Sport car output between 1992 and 1994. This car is in production at the Bloxham near Banbury, and only produced for two years and also very limited in number, which is only 281 units.  Model two-door coupe sedan has a very futuristic body design and very luxurious.Supercar manufacturer of this section reveals the first time in the history of Jaguar, was developed based on the engine used in the Austin Metro 6R4 rally car with a capacity of 3.5 L V6 engine equipped with twin turbochargers use a 5-speed manual transmission. Power generated by the engine is claimed to reach 542 hp at 7000 rpm and torque of 476 lb-ft (645 Nm) at 4500 rpm, enough to make it reach a top speed of 217 mph (350 km / h). Jaguar XJ220 capable of reaching speed of 60 Mph from the stop position in just 3.8 seconds. This makes the Jaguar XJ220 had seized a record for a production car with a top speed of 217 mph (350 km / h).
