Upcoming Ford’s new downsized 1.0 litre Ecoboost
Fords new 1.0-litre, three cylinders, straight inoculation Eco enhance tank engine blows fine above its weight with both 99bhp and 118bhp versions approaching. Its intended not just for the likes of the Ka and Fiesta as we might be expecting, but presentation in the hub and its also meant the C-Max and impending B-Max. Engineers are still thinking appropriate it to the subsequently Mondeo or Fusion.
Ford engineers have set aside the price down on the extremely higher little three vessels in a number of conducts. The chunk is minute, so little that its footprint is about the size of a sheet of A4 paper and because of that, the weight saved making it from lightweight alloy would be unimportant, so it’s made of cheaper shed iron which broadcasts less sound. The cool system is also dividing between head and block for quicker limbering up.

Six-stroke engine
The six-stroke engine is a type of internal combustion engine based on the four-stroke engine, but with additional complexity intended to make it more efficient and reduce emissions. Two different types of six-stroke engine have been developed since the 1990s:
In the first approach, the engine captures the heat lost from the four-stroke Otto cycle or Diesel cycle and uses it to power an additional power and exhaust stroke of the piston in the same cylinder. Designs use either steam or air as the working fluid for the additional power stroke. The pistons in this type of six-stroke engine go up and down three times for each injection of fuel. There are two power strokes: one with fuel, the other with steam or air. The currently notable designs in this class are the Crower six-stroke engine, invented by Bruce Crower of the U.S. ; the Bajulaz engine by the Bajulaz S.A. company of Switzerland; and the Velozeta Six-stroke engine built by the College of Engineering, at Trivandrum in India.
The second approach to the six-stroke engine uses a second opposed piston in each cylinder that moves at half the cyclical rate of the main piston, thus giving six piston movements per cycle. Functionally, the second piston replaces the valve mechanism of a conventional engine but also increases the compression ratio. The currently notable designs in this class include two designs developed independently: the Beare Head engine, invented by Australian Malcolm Beare, and the German Charge pump, invented by Helmut Kottmann.

Ferrari F40
The Ferrari F40 is a mid-engine, rear-wheel drive, two-door coupé sports car produced by Ferrari from 1987 to 1992 as the successor to the Ferrari 288 GTO. From 1987 to 1989 it held the title as the world's fastest street-legal production car, and during its years of production, was Ferrari's fastest, most powerful, and most expensive car. The car had no traction control, and was one of the few to utilize turbochargers.
The car debuted with a factory suggested retail price of approximately US$400,000, although some buyers were reported to have paid as much as US$1.6 million. A sum of 1,315 F40s were produced.
McLaren F1
The McLaren F1 is a super car designed and manufactured by McLaren Automotive. Originally a concept conceived by Gordon Murray, he convinced Ron Dennis to back the project and engaged Peter Stevens to design the exterior of the car. On 31 March 1998, it set the record for the fastest road car in the world, 240 mph (386 km/h). As of Jan 2011, the F1 is still the fastest naturally aspirated road car in the world.
The car features numerous proprietary designs and technologies; it was designed and built with no compromises to the original design concept laid out by Gordon Murray. It is lighter and has a more streamlined structure than even most of its modern rivals and competitors despite having one seat more than most similar sports cars, with the driver's seat located in the middle (and slightly forward of the passengers seating position providing excellent driving visibility). It features a powerful engine and is somewhat track oriented, but not to the degree that it compromises everyday usability and comfort. It was conceived as an exercise in creating what its designers hoped would be considered the ultimate road car. Despite not having been designed as a track machine, a modified race car edition of the vehicle won several races, including the 24 Hours of Le Mans in 1995, where it faced purpose-built prototype race cars. Production began in 1992 and ended in 1998. In all, 106 cars were manufactured, with some variations in the design.
