23-461: The Lamborghini Reventón ( Spanish pronunciation: [reβenˈton] ) is a mid-engine limited production sports car that debuted at the 2007 Frankfurt Motor Show . The official press release stated that only 20 vehicles would be sold to the public, with one additional car (marked as 00/20) produced for the Lamborghini museum. Each car is stamped with its number in the sequence of 20 between

46-518: A rear wheel drive powertrain where the power is sent to the rear wheels . This design is cheaper than the M4 design because of the limited parts required to make the system function. Manufacturers use a unique layout to balance the weight distributed between the front and rear axles. Having a front engine layout with a rear wheel drive powertrain almost evens out the weight distributed in order to optimize performance and handling. Most mid-engine cars, because of

69-463: A "g-force-meter" which displays the magnitude and direction of the g-forces acting upon the car. The seats of the Reventón are made from black leather and brown Alcantara. The Reventón features an all-new carbon-fiber exterior. All cars have the same exterior color, described as "mid opaque grey without the usual shine." It is the first Lamborghini automobile to incorporate daytime running lamps into

92-415: A corner at high speeds the car may enter the corner and understeer and then half-way through the corner suddenly start to oversteer. Roll cage A roll cage is a specially engineered and constructed frame built in (or sometimes around, in which case it is known as an exo cage) the passenger compartment of a vehicle to protect its occupants from being injured or killed in an accident, particularly in

115-614: A maximum speed of over 340 km/h (211 mph). Of the original 20 coupes, 10 were delivered to the United States, seven to Europe, one to Canada, and two to Asia. One of them is in the possession of the Head of Chechen Republic, Ramzan Kadyrov . A roadster variant of the Reventón was unveiled at the 2009 Frankfurt Motor Show . The roadster uses the engine used in the Murciélago LP 670–4 Super Veloce . In June 2009, Autocar published

138-450: A report saying that potential buyers have been shown the car, although a Lamborghini spokesman told the publication that reports of the car were "just speculation". Production was set for a run of 15 units, with a MSRP of €1,100,000. The actual price, however, increased twofold to around US$ 2,100,000, due to high demand. The Reventón Roadster has more power than its coupe counterpart, at 670 PS (661 hp; 493 kW) at 8,000 rpm, but

161-574: Is essentially a roll bar spanning the width of a passenger's shoulders. A newer form of rollover protection, pioneered on the Mercedes-Benz R129 in 1989, is deployable roll hoops that are usually hidden within the body of a car. When sensors detect an imminent rollover, the roll hoops quickly extend and lock in place. Cars that have a deployable rollover protection system include the Peugeot 307 CC, Volvo C70 , Mercedes-Benz SL 500 , Jaguar XK , and

184-419: Is then sent down a shaft to a differential in the centre of the car, which in the case of an M4 layout, distributes power to both front and rear axles . The centre differential contained within many 4 wheel drive cars is similar to the conventional differential in a 2-wheel drive car. It allows torque to be distributed to both drive axles whilst allowing them to spin at different speeds, which vastly improves

207-406: Is usually where the weight of a car is most concentrated so placing it between the front and rear axles gives a car a much better handling balance. Assuming the engine is behind the passenger compartment, the engine will also be pushing down on the rear wheels. Because the weight of a car is shifted toward the rear under acceleration in all cars as a rule, this further improves the amount of grip on

230-625: The Aventador . The active rear wing and the active air intakes integrated into the car's shoulders are electronically controlled, deploying automatically only at high speeds in an effort to maximize both aerodynamic and cooling efficiency. The engine is the same unit used in the Murciélago LP 640 , a 6,496 cc (6.5 L; 396.4 cu in) V12 , now upgraded to 650 PS (641 hp; 478 kW) at 8,000 rpm and 660 N⋅m (487 lb⋅ft) of torque at 6,000 rpm. The car accelerates from 0-100 km/h (62 mph) in 3.4 seconds and can attain

253-459: The amount of torque going to the front and rear wheels, and therefore vary how much the car behaves like a front- or rear-wheel-drive car. This means that through a fast corner the car is able to display more "neutral" handling - with less oversteer or understeer . This is a much more efficient means of turning and allows for faster cornering speeds as opposed to a two-wheel or conventional four-wheel-drive system. Some cars are designed with

276-409: The car's occupants in the event of a rollover . M4 layout It is a type of car powertrain layout. Although the term " mid-engine " can mean the engine is placed anywhere in the car such that the centre of gravity of the engine lies between the front and rear axles , it is usually used for sports cars and racing cars where the engine is behind the passenger compartment. The motive output

299-434: The case of a flower (a carnation, un clavel reventón ) in its maximum point, of luxuriance or a mouth ( una boca reventona ), for its beauty and fullness. The instrument panel in the Reventón consists of three TFT liquid crystal displays (LCDs) with two different display modes. The instruments are housed in a structure milled from a solid aluminium block, protected by a carbon-fiber casing. The car's instrumentation includes

322-423: The cornering of a 4-wheel drive car on surfaces with high grip such as tarmac. However, unlike the differentials on the drive axles which are configured to provide torque equally to both wheels, the centre differential is usually set to have a bias to one set of drive wheels or the other, depending on application of the car. Some 4 wheel drive cars use a centre viscous coupling unit that will provide most power to

345-408: The driver and passenger seats. While the exterior is new, almost all the mechanical elements, including the engine, are sourced directly from the Murciélago LP 640 . According to the official press release, the Reventón's exterior styling was inspired by "the fastest airplanes". The car is named after a fighting bull , in line with Lamborghini tradition. The bull, raised by Don Heriberto Rodriguez,

368-462: The event of a rollover . There are many different roll cage designs depending on the application. Hence, various racing organizations have differing specifications and regulations, although most of these organizations harmonize their rules with those of the FIA . Roll cages help to stiffen the chassis , which is desirable in racing applications. Racing cages are typically either bolt-in or welded-in, with

391-407: The former being more straightforward and cheaper to fit while the latter is stronger and more substantial. A roll bar is a single bar behind the driver that provides moderate rollover protection. Due to the lack of a protective top, some modern convertibles utilize a strong windscreen frame acting as a roll bar. Also, a roll hoop may be placed behind both headrests (usually one on older cars), which

414-424: The headlamps. Seven light-emitting diodes (LED) at each headlamp flank the bi- xenon main beam and stay lit whenever the car is in motion. Due to the high temperatures in the rear lower part of the car, special heatproof LEDs are used for the indicator and hazard lights, stoplights, and rear lights with a triple arrow optical effect. The Reventon's exterior design formed the basis for the company's subsequent flagship,

437-446: The rear wheels unless the amount of torque being supplied to the rear wheels is in excess of the traction limits of the rear tyres, such as in a Lamborghini Murciélago . Others contain a computer that will decide how much power to distribute to any wheel at any time depending on the circumstances of each wheel. In general the M4 system is not widely used as it is suited toward sports cars and some off-road racing vehicles . The engine

460-425: The rear wheels, increasing the amount of torque that can be supplied to the rear wheels before wheelspin occurs. Because the engine is not in the front, the car can be designed with a minimum amount of frontal area perpendicular to the wind, greatly increasing aerodynamic efficiency. A computer-controlled four-wheel-drive differential system allows a car to both accelerate and corner more quickly, since it can vary

483-401: The same level of torque and a slightly lower top speed of 205 mph (330 km/h). This is due to the chassis reinforcing components to compensate for the loss of the roof that add 25 kg (55 lb) to the weight of the car. 0-100 km/h (62 mph) acceleration reportedly remains the same at 3.4 seconds. The car also features deployable roll hoops which quickly extend to protect

506-409: The size and position of the engine and transmission, compromise heavily on both passenger and boot/trunk space. Four-wheel-drive systems tend to be quite heavy and some of the engine's power can be lost through the various differentials in the car, in addition to the frictional losses of the powertrain . The variable handling characteristics of a four-wheel-drive car mean that when travelling round

529-508: Was best known for killing famed Mexican bullfighter Felix Guzman in 1943. Reventón means "small explosion" or "burst" in Spanish, when used as a noun. In automotive terms, it means "blowout or flat tire" when used as a noun. When it was used as the name of a bull, however, it was intended to be interpreted as an adjective, a quality or property of that bull in particular. In this last sense, reventón means "he who seems to be about to burst". Or, in
