10 Best Car Engine 2011
After learning the names of the ’10 Best Engines’, the enlisted just have to wait for the start of the next Auto Show in Detroit for the award ceremony. As every year the American journal Ward’s Automotive specializes unveiled its annual list of the best engines in 2011. Every year, almost 20, Ward’s journalists announce what, in their opinion, the best engines in the coming year to be mentioned in a spectacular Top Ten: ie “‘s 10 Best Engine Award 2011.”
So a few days of the end 2010, the nominations for the 2011 models and were released between 38 and newer models who took part in the race, it was determined the 10 Best Engines, the result is not surprising, since it is consistent the diversity of cars involved.
And for the first time in the history of the contest the results reflect a renewal so big with only two models and six repeating their participation completely new winners.
The decrease in the size and engine displacement does not mean a reduction in power, the era of the big V8 engines fall behind, leaving these machines for competing cars or very specific niches.
In this 4-cylinder engines have the performance of a V6 while the six-cylinder equal to eight, so do not be surprised the power or torque, thanks to turbochargers and compressors that are more efficient combustion with that energy loss is reduced.
Different
It should be noted that 2011 will be a historic year for Ward’s, because among the winners of the Award’s 10 Best Engine “included the first ever appointed electric motors, the Chevrolet Volt and Nissan Leaf. Was once again the machine diesel Volkswagen Jetta TDI (finalist last year), and large machines like the 5.0 liter V8 Ford Mustang 2011, and the Hyundai Genesis. In addition, attracting a new protagonist: the newly released 3.6-liter V6 Chrysler Penastar beginning to be starring with awards and accolades.
To be eligible for competition, ie belong to the list of competitors, “Ward’s 10 Best Engines”, the car must cost less than $ 55 000 in the U.S. and the engine had to be already available in the first quarter of 2011.
To select the winners, during October and November, the editors of Ward’s Automotive tested vehicles of different brands in mixed urban cycle around the Detroit metropolitan area, which assessed according to their power, fuel economy, noise , vibration, torque, refinement and technological relevance, also clear from the comparison of data.
Electrical
Electric vehicles arrived, and they did to stay, so it is not surprising that among the 10 best engines of 2011 two units are powered by electricity: Leaf Nissan and the Chevrolet Volt.
How cars will become more common, Nissan Leaf, the first Model 100 percent power and mass production of Japan’s home, and was recognized as the European Car of the Year (COTY 2011), while Chevrolet Volt, was his own with the publication Motor Trend and the “Green Car of the Year 2011″ from the Los Angeles Auto Show in North America. This, in a clear way of changing technologies and new generations of cars in which the power supply will be gradually replaced by electricity in exchange for the gradual disuse of fossil fuels.
So Ward’s only corroborates the importance that the power is to the automotive world, with its choice, that if the total of 10 “Best Engines”, two of which correspond to present 100 percent power as in the case of Nissan Leaf or Extended Range Electric, as the little 1.4-liter engine that recharges the batteries for the Chevrolet Volt to extend their autonomy.

Williams dismayed by early 2011 performance
Williams dismayed by early 2011 performance
Published: 13/04/11, 05:22PM
Williams chairman Adam Parr and technical director Sam Michael have admitted they are deeply disappointed with the team’s performance in the first two races of the season, which they say has fallen far short of their expectations.
The Grove-based squad’s radical 2011 car design – which features an ultra-compact gearbox and very tightly packaged rear end – showed promise in winter testing but did not replicate that pace in Australia and Malaysia, while driver errors and a variety of reliability problems have compounded the team’s woes.
Williams have languished near the back of the midfield group so far and are the only established team yet to get on the scoreboard.
“Like everyone at Williams, I am both surprised and frustrated with our start,” said Parr.
“In spite of having an ambitious concept for the FW33, the benefit of continuity with our engine, and moving into our second season with Rubens [Barrichello], we have come up short.
“It is particularly bad in view of our relative strength in pre-season testing and the exceptional amount of work that everyone across Williams has put into this car.”
Parr said the reliability problems have hindered the team’s efforts to develop the FW33.
“First, we have to understand where we are strong and where we are weak. We have had some notable areas of success with the FW33 and we can build on these. We also have some promising improvements coming through for Shanghai and Istanbul and we need to see how these perform.
“We also need to get on top of the reliability issues because these not only affect immediate performance, they also absorb resources that should be focused on improvement.”
Michael was equally blunt in his assessment of the team’s showing last weekend, saying: “Our performance was well below expectations in many areas in Sepang.
“This is not acceptable for us and we’ll be thoroughly reviewing all aspects of our lack of performance before Shanghai.”
Michael detailed the technical problems that sidelined Barrichello and Pastor Maldonado in Malaysia: “Rubens retired with a differential seal leak, caused by excessive slip on the differential during the lap when he had a puncture.
“Pastor retired with a misfire from the engine. The most likely cause of this was a faulty ignition coil, but Cosworth are still investigating this.”
Both Parr and Michael hinted that an overhaul of the team’s engineering group might be necessary to improve performance in the medium term.
“Ultimately the performance and reliability of the car is down to the engineering group and we’ll respond accordingly,” said Michael.
Parr added: “We will move forward, but that does not alter the fact that we have started too far behind.
“Therefore, we will be looking not only at how to address the short-term issues – we will be working together to strengthen the team for 2012 and beyond. Every aspect will be reviewed, nothing is sacred, but we will do this methodically and not in a reactive way.”
