The PowerTech was a new engine family for Chrysler that could not have been designed by Mercedes Benz because the take-over of Chrysler Corporation didn't happen until1998, and was not based on the Chrysler A engine as existing Chrysler V8s were.
 A 4.7 L V8 came first, fitted in the Jeep Grand Cherokee, and a 3.7 L V6 version debuted in 2002 for the Jeep Liberty.
 The PowerTech V6 and V8 were direct replacements for Chrysler's "LA" family in the early 2000s, and were also used in the Dodge Ram and started in the 2000 Dodge Durango .
 They were not used in any cars, but were reserved for truck and SUV use.
 They are also known as Next Generation Magnum in Dodge applications.The PowerTech V6 and V8 engines are produced at the Mack Avenue Engine Complex in Detroit, Michigan.
 E85 compatible versions of some PowerTech engines were developed and used in numerous Chrysler vehicles.
 On April 9, 2013 the last 4.7 L engine was built; ending 15 years of production with over 3 million examples built.
Volkswagen's VR6 engines, and the later VR5 variants, are a family of internal combustion engines, characterised by a narrow-angle (10.5° or 15°) V engine configuration.
 Developed by the manufacturer in the late 1980s, evolutions of these engines are still produced by them.
Life was a Formula One constructor from Modena, Italy.
 The company was named for its founder, Ernesto Vita ("Vita" is Italian for "Life").
 Life first emerged on the Formula One scene in 1990, trying to market their unconventional W12 3.5-litre engine.
Lebanon hosted the 3rd Mediterranean Games in Camille Chamoun sports city in Beirut.
 The event took place from 11 to 23 October 1959.
 11 nations were represented by a total of 792 athletes, all males, competing in 17 sports of 106 events.
 France came first: its 66 athletes won 69 medals (26 gold), while the host country, Lebanon, with the most athletes (180), came 8th with 30 medals (only 3 golds).
 The United Arab Republic, participating for the first and only time as Egypt and Syria, came second (the UAR in the 1963 games included only Egypt).
A W12 engine is a twelve cylinder piston internal combustion engine in a W configuration.
 W12 engines have been manufactured in two distinct configurations.
 The original W12 configuration used three banks of four cylinders coupled to a common crankshaft, with 60° angles between the banks.
 These were used in several aircraft engine designs from the 1920s, notably the Napier Lion and various French engines.
 The more recent configuration, used in the Volkswagen Group W12, uses four rows of three cylinders merged into two 'cylinder banks' (two narrow-angle VR6 engine blocks), coupled to a common crankshaft.
At first the model had a new petrol engine with 1395 cc and 29 kW (39 hp) at 3800 rpm to 1400 Fiat, and had a manual 4-speed transmission.
 A 1.5 ton truck was newly developed, which was offered from 1951 in a flatbed and chassis for special bodies.
 It was powered by the engine of the prior year featured Fiat 1400s.
 The engine was already in the car Fiat 1400 was just sufficient, and with the 3.1 tons it had real trouble.
 Once in motion, the Fiat 615 was indeed 80 km/hr fast, but with forced driving it had poor fuel efficiency.
 There was a reason that the 1100 Fiat ELR far built until 1954.
 The somewhat weaker beast of burden was, with its 1.1 liter and 28/30 PS (at 4400 rpm) a little lame, but it had fully loaded a ton to move less weight, so was more economical.
 It therefore retained its loyal following who forgave its manageable liveliness out of habit, especially as it came with start-up to a peak of over 90 km/hr and thus was significantly faster than the Fiat 615 with its maximum of 78 km/hr.
 With high pressure, therefore a suitable diesel engine was developed by Fiat: a swirl chamber engine (Ricardo System) based on the 1.9 liter engine for the "big" Fiat in 1900 and the new SUV Fiat Campagnola.
 (This engine was a hubvergrößerte variant of the 1400 engine.)
 The new diesel engine (type 305) was later also available in either sedan 1400 from 1952 in addition to the Fiat 615 N (N = Nafta = Diesel) and one year in Fiat Campagnola and Fiat.
 Although the experiment of the Fiat 615 built 1.9 L gasoline engine proved to be stronger and with faster drive spurt, confined themselves to the diesel, the Type 615 N. Only Steyr in Austria until 1958 offered the Fiat 615 as gasoline, as Steyr 260 with its own 50 hp 2 L gasoline engine from the car Steyr 2000.
 The Fiat 615 N was a very modern vehicle that in Italy, initially had no competition.
 The export ran well at the beginning, missing, or half-hearted development left the Fiat 615 N (and especially its successor) over the years become increasingly rare even in Italy.
 In Zastava in Yugoslavia, the Fiat 615 was built with a petrol engine under license.
 However, not as the beginning of the Fiat, with the 1.4 L 4-cylinder engine, but with the much stronger torque 1.9 liter engine (type 105) with 47 hp at 3500 RPM, as well as in the, also at Zastava built under license, Campagnola was used.
 It is unclear whether the successor (from about 1963, as Fiat 615 N1) only with the 1.9 liter petrol engine (such as 615 B) was built, with a diesel engine.
The High Value engine family from General Motors is a group of Cam in Block or "Overhead valve" V6 engines.
 They use the same 60° vee bank as the 60° V6 family they are based on, but the new 99 mm bore required offsetting the bores by 1.5 mm away from the engine centerline.
 These engines (aside from the LX9) are the first cam in block engines to implement Variable Valve Timing, and won the 2006 Breakthrough Award from "Popular Mechanics" for this innovation.
 For the 2007 model year, the 3900 engine features optional displacement on demand or "Active Fuel Management" which deactivates a bank of cylinders under light load to increase highway fuel economy.
 It was rumored GM would produce a 3-valve design, but that never came to be.
 These engines were produced primarily at the GM factory in Tonawanda, New York and at the Ramos Arizpe engine plant in Mexico.
 The assembly line for this engine was manufactured by Hirata Corporation at their powertrain facility in Kumamoto, Japan.
Sven-Harry Åkesson, born March 12, 1940, is an automobile designer from Sweden.
 His first car was built in 1959 as a Formula Junior racer, but after a while he came to the conclusion that it was going to be too heavy so he abandoned the build.
 In 1961 he started another Formula Junior build he called "Spider Mark I".
 It was 3.5 metres long with a wheelbase of 2.2 metres.
 At the highest point it was only 77 centimetres high.
 The engine was a BMC A-Series engine mated to a Volkswagen gearbox.
 The steering came from a Lloyd and the brakes were originally from a Fiat, but rebuilt.
 In 1962 he built a Mark II also powered by a BMC-A engine.
 In 1965 came the "Spider Mark III", still with a BMC-A engine, but now tuned by Speedwell.
 It was followed by the Mark IV.
 He kept producing a new car each year for himself and some other interested buyers.
 About 20 formula cars were made.
Bentley EXP 10 Speed 6 is a hybrid concept car by Bentley launched in 2015 at the Geneva Motor Show.
 Bentley has said that the EXP 10 Speed Six will go on sale between 2018 and 2020, and will be available in coupé and roadster versions, with an all-electric version using a similar powertrain as the Porsche Mission E, being available.
 A V6 plug-in hybrid and V8 engine variants, as well as a possible W12 engine may also be available.
Suzuki F10D engine is an inline 4-cylinder 1061cc engine that was developed in India by Maruti Suzuki for the domestic market.
 It was debuted in the Maruti Wagon-R in India in 2001.
 It was briefly installed in Maruti Alto and it was the engine that the first Maruti Zen Estilo came with.
 This engine is very similar to the 3-cylinder F8D 12-valve engine that was optional on the Maruti 800 at the time.
 The bore and stroke of F10D is the same as that of the smaller sibling and shares quite a few parts like pistons, rings, conrods and valves.
 The cast-iron engine block is very similar to that of the older F10A 970cc engine that powered the earlier Maruti Gypsy and Maruti 1000.
 Both F10A and F10D shares the same stroke length; but interchangeability of parts between these two engines is not known.
