Most of the time, concept cars arenâ€™t really cars. They have no engines, or can only move at very slow speeds. Sometimes, the door donâ€™t even open. Concept cars are all about visual impact; they show what car companies are capable of with their styling. However, there is at least one concept that makes noise when you press the starter button. The Bertone Nuccio was originally unveiled at the 2012 Geneva Motor Show, as a celebration of the Italian styling houseâ€™s 100th anniversary. Now, the Nuccio is making a second appearance at the Beijing Motor Show, and Bertone says it is fully drivable.
Underneath the stylish skin is the chassis from a Ferrari F430, the car that preceded the 458 Italia. The Nuccio retains the F430â€™s 4.3-liter V8, but the engine has been tuned to produce 480 horsepower instead of the Ferrariâ€™s 490. However, Bertone says the Nuccio is lighter than an F430, so it will be interesting to see if there is any difference in straight-line performance. The V8 is mated to the Ferrariâ€™s six-speed transmission, which features Formula 1-style paddle shifters. The transmission is less sophisticated than the double-clutch unit in the 458, but itâ€™s better than nothing.
Bertone made one unorthodox alteration to the Nuccioâ€™s lights to make the car road-worthy. The running lights glow brighter when the car is braking; Bertone says this is to alert pedestrians that the car is slowing at intersections. After all, isnâ€™t it better to have more, even when it comes to brake lights? The Nuccioâ€™s headlights appear to be taken from the same F430 donor.
The Nuccio is one of the only concept cars to have a full interior. It is toned down a bit from other concepts, but itâ€™s also more functional. You donâ€™t control the throttle with a touch pad, but you do get heavily bolstered sport seats and an inclined center console that brings controls closer to your right hand. Like the outside of the car, the interior gets a splash of orange to contrast with the mostly gray surfaces.
The Nuccio is named after Nuccio Bertone, the son of company founder Giovanni Bertone. Nuccio ran the company from 1950 until his death in 1997, and produced some of Bertoneâ€™s most memorable designs. To honor him, current Bertone designers took styling cues from three of the styling houseâ€™s greatest cars: the 1968 Carabo, 1970 Stratos Zero, and 1973 Lamborghini Countach, to create the Nuccio.
Itâ€™s easy for a concept car to look good while rotating on an auto show stand, but these vehicles are usually too fragile for the real world. Bertone tried to change that, and hopefully the Nuccio will turn as many heads on the road as it did at Geneva and Beijing.
If you can get over the fact that you’ll never be able to drive anyone but yourself in the Miluira, then you might understand what’s so special about it â€” it’s electric and has slick retro looks. Really, the Miluira looks like something Henry Ford would design if he were alive today.
Despite its detailed stylings, the Miluira disappoints in being, you know, a car. It can only reach a top speed of about 37 mph and travel up to 21 miles before requiring a pit stop at an EV station. The Miluira can probably be classified as more of a souped-up go-kart than as a real car.
Lucky for you, the Miluira is not another concept car. It’ll be available in March 2011 for about Â¥6.3 million or roughly $76,000.
Experienced driver friends all know that cars on the “three-filter” in car use is very important, it is equivalent to the role of the masks that people often use is to block harmful substances into the car essential. Therefore, only ensure that they are clean, car will maintain physical health.
The so-called “three-filter” refers to the air filter, oil filter and fuel filter, and their role in the name suggests, is the filtration and purification into the car engine inside any gas and liquid, and thus play a protective effect on the engine, but also can improve engine efficiency.
The air suspension with a lot of dust, the main component is silicon dioxide, which is a harder material than metal. The installation of air filter can reduce the cylinder, piston and piston rings and other parts of the wear and tear. Cars, if not install it, will increase seven-fold cylinder wear, piston wear increased by 3-fold increase of 8 times the piston ring wear. Therefore, in the modern automobile engine equipped with a carburetor air filter. General clean once a travel 5,000 kilometers. Cleaning should remove the filter element gently pat face, using compressed air machine blowing from the inside out to remove the dust on the core, do not use gasoline or water washing, driving 25,000 kilometers air filter needs to be replaced.
Internal combustion engine using the process, dust, metal wear and tear, carbon-ching and other mechanical impurities mixed with oil will continue in the same time, the emission of air and burning oil oxidation also make oil gradually produce gelatinous. Mechanical impurities mixed with the resin will form a sludge, which will not only speed up the movement part of the wear and tear, but could easily lead to blockage of asphalt. In order to ensure clean asphalt, engine lubrication system with oil filter. In addition, together with Chi Pu-resistant cleaning agents inside the engine can better guarantee the smooth flow of asphalt. Most of the current car is to install rotary-mounted oil filter, it is only a one-time filters can not be cleaned, it is best to replace the oil at the same time replace the oil filter, otherwise it will affect the oil quality, and general travel 5,000 km to replace one is appropriate.
As the cars in storage and transportation and the filling process will inevitably be mixed with a number of impurities and moisture, these impurities with the fuel into the fuel supply system and the engine cylinder, the cylinder will accelerate the wear and tear of petrol into the fuel pump must be pre – filtration to ensure the gas supply system work properly. At the same time with the Chi Pu-resistant fuel system cleaners results will be even better. Now that the petrol filter is also a one-time use, and its replacement cycle of about 10,000 kilometers in the most appropriate.
Do a good job “three filter” conservation work, for car maintenance and driving safety engine has a very important role, hope that the majority owners will not overlook this aspect.
We have in the face of the market will find all kinds of car, car engines also have different styles and different techniques, many people have this question, in the end what the engine is the best?
What is the best engine in the end?Â From the market point of view, this is a so no one can accurately answer the question, because the car’s design principles in such an industry self-evident rules – just right! Â Should pay attention to what a reasonable match nature of automotive design is to emphasize the best combination.
Although the automotive market, we have the luxury of power is not difficult to find some configuration examples, but not the mainstream of the development direction of cars, at present we are in the market the most common and also the people most frequently mentioned problem is that high-class car market, the most common form of in-line four-cylinder engines and V-type 6-cylinder, why is there such phenomenon?Â How should we choose?
Here,Â these two kinds of engines to conduct a comprehensive comparison:
1, the basic concepts.
Â From the traditional sense, the six-cylinder engine to meet the needs of a larger displacement and more power as a design, it is generally six-cylinder engine’s displacement is greater than 4-cylinder engine, but due to in-line six-cylinder engine will make the length of difficult to place, so they gave birth to the cylinder was “V”-shaped layout of the engine, which is V-type 6-cylinder engine.
Â V-type 6-cylinder engine, compared with the in-line 4-cylinder engine, although greatly reduced in length, but in comparison with the in-line 4-cylinder engine weight is still a weak one, because there must be two sets of air intake system V6 engine and two cylinder heads , parts, therefore the heavier the engine, while the four-cylinder machines can reduce the weight of even 30%.Â However, the weight of a direct impact on the car’s power and economy, especially the fuel economy was seriously affected, which is lighter in the car today for further in-line 4-cylinder engine can still be an important factor in the main engine .
Â 2, technical features.
Â Overall: V6 engine is more lenient, but generally shorter than the in-line four-cylinder engine, front-precursor used in most cars where the engine transversely mounted, the engine compartment it is very cramped space in the installation and maintenance convenience is obviously not as good as in-line 4-cylinder engine, V6-cylinder engine while the technical requirements for fixed mount much higher.
Â Structure: in-line 4-cylinder engine of simple structure, coupled with the engine compartment when placed around the room more Graceful ease, so the air-cooled cylinder cooling is better.Â Displacement in the same or close to, the four-cylinder machine to be bigger bore, the corresponding area of the combustion chamber will be bigger, V6-cylinder engine bore is small, the combustion chamber of each cylinder corresponding to the area to be small, in-line 4 Valve-cylinder engine with a simple layout, while cylinder block, cylinder head and crankshaft structure is relatively simple compared to the V6 engine is much more complex.
Â Features: compared to a similar power in the l case, the in-line 4-cylinder engine speed slightly lower for power frequency is less than V6 engines, V6 engines to power it, good stability, while the in-line 4-cylinder engine to power a number of poor stability, in the high-speed operation of the engine speed on the road, the V6 engine is relatively smooth and noise less impressive, so common in-line 4-cylinder engines make more use of balancer shaft to improve its functioning smoothly, whereas added a balancer shaft in-line 4-cylinder engine running smoothness can be achieved with the V-type 6-cylinder engine is very close results.Â In addition, the in-line 4-cylinder engine running at low speed when the torque characteristics are better, more suitable for urban environments.
Use: In general, in-line four-cylinder engine can use a lower compression ratio, it is generally in-line four-cylinder engine can use low-grade gasoline, the economy is good.Â In-line 4-cylinder engine versatility, the basic emission below 2.5 can cover all the products, while the V6-cylinder engine is only applicable to large displacement of the high-end cars, use of a small.Â In-line 4-cylinder engine technology is mature, simple structure, easy to maintain, and performance is stable, while the V6-cylinder engine on the complexity of processing technology, the relative quality of factors of instability there is a little more.
Maintenance: As in-line 4-cylinder engine, simple structure, stable quality, maintenance facilities, have an advantage, while the V6-cylinder engine complex structure, maintenance, technical requirements are higher, quality is relatively difficult to guarantee, and the maintenance of higher prices.Â In the routine maintenance costs, the in-line 4-cylinder engine maintenance and low cost advantages are obvious.Â Currently, BMW is still using in-line cylinder engine technology.
3, the market forecast.
Â Energy-saving environmental protection in recent years widespread appeal, as well as engine technology advances, especially as the engine of new electronic control technology, the rapid development of automobile engine displacement is also declining.Â A small displacement, turbo-charged, multi-valve, variable valve timing, variable intake manifold, cylinder fuel injection and other technologies have become the future development of the typical technical characteristics of the engine. For now, many in-line 4-cylinder engine has reached or exceeded the V6-cylinder engine performance. In addition, from the present perspective of the development of international automobile industry, automobile industry has entered the era of little profit, which is bound to restrict their development investment in new high-performance inline four-cylinder engine will have a wider application value.
Â 4, some recommendations.
Â As we stated earlier, different engines have different strengths and weaknesses, it is difficult to say who has the absolute advantage. Want to emphasize in particular is that we choose the engine when not necessary to choose the largest displacement, but be sure to choose the most appropriate; you may not power the biggest, but be sure to choose the most cost-effective; not necessarily have to Choose the most advanced technology, but be sure to choose the most reliable. I am particularly in favor of the Mazda Core-wing ideas advocated by the engine, practicality = actual use value.Â In short, power, performance, energy saving, environmental protection, reliability, is a not small.
