The Infiniti QX is a luxury SUV built by Nissan and originally sold in North America. The first generation received its naming inspiration from the recognized four wheel drive terminology "4×4" with Infiniti adding a "Q" at the beginning to suggest it was a luxurious "4×4", borrowed from the Q45. The first generation also had a briefly available Japanese version called the Nissan Terrano Regulus. Consecutive generations are much larger, and the naming convention adheres to the current trend of using a numeric designation derived from the engine's displacement.
The Infiniti QX4 is a mid-size sport utility vehicle (SUV) introduced in 1997 as a rebadged Nissan Pathfinder. It was released a year after Acura's introduction of the SLX and Lexus's larger LX 450. The QX4 was Infiniti's first entry into the SUV market segment.
In the North American market, it was marketed as the "Infiniti QX4" while in Japan it was sold as the Nissan Terrano Regulus. Major differences between these vehicles and the Pathfinder include a more advanced four wheel drive system, a more upscale interior, and unique styling. Although marketed as a luxury vehicle, it is capable off-road service due to its low-range four wheel drive system and 8.3 inches (211 mm) of ground clearance.
The QX4 received its first major update in 2001, with a new VQ series engine (also later seen in the G35 and FX35) increasing its power from a relatively low 168 horsepower (125 kW) to a 240 hp (179 kW) V6 engine. The displacement went from 3.3 L to 3.5 L. The timing belt was replaced with a timing chain and the ignition distributor was replaced with an individual coil ignition system.
This 2001 facelift also gave the QX4 an updated exterior and interior body style, including features such as a new dash with integrated analog clock, 17-inch (423 mm) alloy wheels and xenon HID headlamps. In Japan, the Terrano Regulus trim package was no longer offered. Also, a rear-wheel drive model was added (1997 through 2000 were only available in 4WD).

gmc terrain
The GMC Terrain is a mid-size crossover SUV. According to GM, it replaced the GMC Envoy, the Isuzu Ascender, which was discontinued after Isuzu stopped selling their automobiles in America, and Pontiac Torrent, which was sold in the same dealerships prior to GM dropping the Pontiac brand.. Like the Torrent, the Terrain is based on the Theta platform. The Terrain slots below the Acadia as GMC's smallest SUV.
The Terrain shares engineering with the 2010 Chevrolet Equinox. While the two vehicles use the same platform and drivetrain, the Terrain's body panels and standard features differ from those of the Equinox.
The 2010 Terrain debuted at the 2009 New York International Auto Show. Like the preceding Pontiac Torrent, the Terrain will be sold in Mexico.
General Motors also uses the GMC Terrain marque as a rebadged Opel Antara in the Middle East, that shares the same Theta platform. This vehicle is similar to the Saturn Vue and Chevrolet Captiva.

mercury element
Mercury is a chemical element with the symbol Hg and atomic number 80. It is also known as quicksilver or hydrargyrum (from "hydr-" water and "argyros" silver). A heavy, silvery d-block element, mercury is the only metal that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is bromine, and metals such as caesium, francium, gallium, and rubidium melt just above room temperature. With a freezing point of −38.83 °C and boiling point of 356.73 °C, mercury has one of the narrowest ranges of its liquid state of any metal.
Mercury occurs in deposits throughout the world mostly as cinnabar (mercuric sulfide). The red pigment vermilion is mostly obtained by reduction from cinnabar. Cinnabar is highly toxic by ingestion or inhalation of the dust. Mercury poisoning can also result from exposure to water soluble forms of mercury (such as mercuric chloride or methylmercury), inhalation of mercury vapor, or eating seafood contaminated with mercury.
Mercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, some electrical switches, and other scientific apparatus, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alcohol-filled, digital, or thermistor-based instruments. It remains in use in scientific research applications and in amalgam material for dental restoration. It is used in lighting: electricity passed through mercury vapor in a phosphor tube produces short-wave ultraviolet light which then causes the phosphor to fluoresce, making visible light.
Mercury is a heavy, silvery-white metal. As compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity. Mercury has an exceptionally low melting temperature for a d-block metal. A complete explanation of this fact requires a deep excursion into quantum physics, but it can be summarized as follows: mercury has a unique electronic configuration where electrons fill up all the available 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f, 5s, 5p, 5d and 6s subshells. As such configuration strongly resists removal of an electron, mercury behaves similarly to noble gas elements, which form weak bonds and thus easily melting solids. The stability of the 6s shell is due to the presence of a filled 4f shell. An f shell poorly screens the nuclear charge that increases the attractive Coulomb interaction of the 6s shell and the nucleus (see lanthanide contraction). The absence of a filled inner f shell is the reason for the much higher melting temperature of cadmium. Metals such as gold have atoms with one less 6s electron than mercury. Those electrons are more easily removed and are shared between the gold atoms forming relatively strong metallic bonds. At its freezing point (−38.86 °C), the density of mercury is 13.534 g/cm3.
Mercury does not react with most acids, such as dilute sulfuric acid, although oxidizing acids such as concentrated sulfuric acid and nitric acid or aqua regia dissolve it to give sulfate, nitrate, and chloride salts. Like silver, mercury reacts with atmospheric hydrogen sulfide. Mercury even reacts with solid sulfur flakes, which are used in mercury spill kits to absorb mercury vapors (spill kits also use activated carbon and powdered zinc).

lamborghini logo
Automobili Lamborghini S.p.A.,[Notes 1] commonly referred to as Lamborghini (pronounced [lamborˈgiːni] ( listen)), is an Italian car manufacturer. The company was founded by manufacturing magnate Ferruccio Lamborghini in 1963, with the objective of producing a refined grand touring car to compete with established offerings from marques like Ferrari.
The company's first models were released in the mid-1960s, and were noted for their refinement, power and comfort. Lamborghini gained wide acclaim in 1966 for the Miura sports coupé, which established mid-engine design as the standard layout for high-performance cars of the era. After a decade of rapid growth, hard times befell the company in the mid-1970s, as sales plunged in the wake of the 1973 world financial downturn and oil crisis. After going through bankruptcy and three changes in ownership, Lamborghini came under the corporate umbrella of the Chrysler Corporation in 1987. The American company failed to return the automaker to profitability and sold it to Indonesian interests in 1994. Lamborghini's lack of success continued through the 1990s, until the company was sold in 1998 to Audi, a subsidiary of the Volkswagen Group, a German automotive concern. Audi's ownership marked the beginning of a period of stability and increased productivity for Lamborghini, with sales increasing nearly tenfold over the course of the 2000s, peaking in record sales in 2007 and 2008. The world financial crisis in the late 2000s negatively affected luxury car makers worldwide, and saw Lamborghini's sales drop back to pre-2006 levels.
Assembly of Lamborghini cars continues to take place at the automaker's ancestral home in Sant'Agata Bolognese, where engine and automobile production lines run side-by-side at the company's single factory. Fewer than 3,000 cars roll off the production line each year. The flagship V12-powered Murciélago coupé and roadster were discontinued at the end of 2010. Its successor, the Lamborghini Aventador, was released on 28 February 2011.
Automobili Lamborghini was founded by Ferruccio Lamborghini, the child of viticulturists from the comune (township) of Renazzo di Cento, Province of Ferrara, in the Emilia-Romagna region of Northern Italy. After serving as a mechanic in the Regia Aeronautica, during World War II, Lamborghini went into business building tractors out of leftover military hardware from the war effort. By the mid-1950s, Lamborghini's tractor company, Lamborghini Trattori S.p.A., had become one of the largest agricultural equipment manufacturers in the country. He was also the owner of a successful gas heater and air conditioning manufacturer.
Lamborghini's wealth allowed him to cultivate a childhood interest in cars, owning a number of luxury automobiles including Alfa Romeos, Lancias, Maseratis, and a Mercedes Benz. He purchased his first Ferrari, a 250GT, in 1958, and went on to own several more. Lamborghini was fond of the Ferraris, but considered them too noisy and rough to be proper road cars, likening them to repurposed track cars. Lamborghini decided to pursue an automobile manufacturing venture, with the goal of bringing to life his vision of a perfect grand tourer.

jaguar c-x16
The car body is constructed from aluminium, and - at 4,445 mm (175.0 in) long, 2,048 mm (80.6 in) wide and 1,297 mm (51.1 in) high - is said by Jaguar to be the smallest car that they have made since the XK120 of 1954. The drivetrain comprises a hybrid unit, combining a 375 bhp (280 kW; 380 PS) 332 lb·ft (450 N·m) supercharged 3-litre V6 petrol engine with a 92 bhp (69 kW; 93 PS) 173 lb·ft (235 N·m) electric motor and an eight-speed ZF automatic transmission. The battery pack, which is mounted behind the front seats, is charged using a brake regeneration system. The car can run on engine alone, motor alone or on both in combination. Under engine power, the electric motor can also be activated to boost acceleration, in a similar way to the KERS system used in Formula 1 cars, by using a switch on the steering wheel.
The C-X16 form takes cues from Jaguar's 2010 C-X75 plug-in hybrid concept supercar, including the shape of the front grille and the wrap-around rear lights, and has a side-hinged opening rear window reminiscent of the 1961 E-Type.
Jaguar's figures give a 0 - 60 mph (97 km/h) acceleration time of 4.4 seconds and a top speed limited to 186 mph (300 km/h). The CO2 rating is 165 g/km. Powered by the electric motor alone, the top speed is 186 mph (299 km/h).

mercedes-benz slr mclaren
The Mercedes-Benz SLR McLaren is an Anglo-German grand tourer car jointly developed by Mercedes-Benz and McLaren Automotive, built in Portsmouth and the McLaren Technology Centre in Woking, Surrey, England and sold from 2003 to 2009. When it was developed, Mercedes-Benz owned 40 percent of the McLaren Group.
Due to the automatic gear box, front mid-engined arrangement, and its driving characteristics, some commentators classify the SLR McLaren as a GT, whose rivals would be vehicles such as the Aston Martin DBS V12 and Ferrari 599 GTB Fiorano.
SLR stands for "Sport, Leicht, Rennsport" (sport, light, racing). Mercedes-Benz stated that they would build 3,500 SLRs over seven years, with an annual production of 500 cars. The car's base price, GB£295,337 (approx. US$450,000, €350,000, CHF 500,000 or C$ 500,000. 2009), made it the ninth most expensive street-legal car in the year 2008.[citation needed]
The Mercedes-Benz SLR McLaren was inspired by the Mercedes-Benz 300 SLR Uhlenhaut Coupe & Racecar of 1955, which was a modified Mercedes-Benz W196 F1 race car. It was introduced on 17 Nov 2003. On 4 April 2008, Mercedes announced they would cease production of the SLR. The last of the coupes rolled off the production line at the end of 2007 and the roadster version was discontinued in early 2009.
The SLR features Sensotronic, a type of brake-by-wire system. The brake discs are carbon-ceramic and provide better stopping power and fade resistance than steel discs when operating under ideal working temperature. Mercedes-Benz claims these discs are fade resistant to 1,200 °C (2,200 °F). The front discs are internally vented and 370 mm (15 in) in diameter. 8 piston calipers are used. Rear discs are 360 mm (14 in) in diameter with 4 piston calipers. During wet conditions the calipers automatically skim the surface of the discs to keep them dry.
