Bentley teases biofuel supercar
Given that the 600-horsepower/553-lb-ft Continental GT Speed currently owns the "most powerful production Bentley" title, look for more extreme ratings on this new, obviously Continental-based monster. As for the biofuel half of the equation, we expect to see an ethanol-drinking version of the twin-turbocharged W12 that propels the rest of the Continental range.

Cuidados com ar-condicionado do seu ve�culo
Tenho um Corsa 1.0 sedan 2000, quando ligo o ar tem um sistema tipo um rele que atraca e diminui o rendimento do ve�culo. O consumo de combust�vel aumenta usando o ar dentro da cidade e na estrada em torno de quantos por cento?
- Sidney
O consumo de autom�vel aumenta com a utiliza��o do ar-condicionado, mas o fator preponderante � a forma de condu��o. Se o motorista n�o imprime fortes acelera��es, se n�o estica as marchas demais e n�o pisa no acelerador sem necessidade, o consumo vai ser menor. Quanto ao condicionador de ar, o seu compressor � ligado ao motor do carro por meio de correias, que por sua vez retira do motor algo em torno de 8 a 15 cavalos de pot�ncia.
O ar-condicionado do meu carro parece n�o resfriar o suficiente. Quando ligado, ele solta um ar gelado, mas n�o chega a ficar totalmente fresco dentro do ve�culo, principalmente para quem viaja no banco traseiro. J� troquei o g�s e n�o resolveu. O que pode estar acontecendo?
- Eliane, Curitiba (PR)
A manuten��o peri�dica do equipamento � que vai garantir seu correto funcionamento. No seu caso, leve o carro a uma empresa especializada em ar-condicionado e pe�a para fazer uma inspe��o geral. N�o basta completar o g�s refrigerante, tamb�m � preciso verificar se n�o h� vazamentos no aparelho.
Comprei um Palio ano 1999/2000, motor 1.0. Ele veio equipado com ar-condicionado, mas este ar n�o � de fabrica. Gostaria de saber se o carro fica comprometido com este equipamento.
- Cidney
O ar-condicionado � um equipamento em que a instala��o n�o � recomendada fora da f�brica. Isso porque pode ocasionar diversas adapta��es que, com o tempo, comprometem algum componente ou mesmo a durabilidade do equipamento. O mais comum � a infiltra��o de �gua no interior do ve�culo, al�m de problemas el�tricos, j� que conforme a adapta��o, mesmo em concession�rias, pode ser utilizada pe�a paralela. Um bom exemplo � a correia do alternador, que tamb�m vai girar o compressor. Em algumas instala��es fora da f�brica, a correia utilizada patina e n�o aciona adequadamente o alternador, que por consequ�ncia n�o carrega a bateria corretamente. O final disso tudo � que o motorista pode ficar na m�o.
Com chuva, uso normalmente o ar e o desemba�ador traseiro?
- Fernando Fortes
Exatamente. Em dias de chuva, o uso do condicionador de ar pode ser normal. Lembre-se apenas de alternar a sa�da do ar e direcionar para o p�ra-brisa por um determinado tempo e depois para o interior do carro. Fique atento quando a sa�da de ar estiver direcionada para o p�ra-brisa. Nessa posi��o o recirculador de ar fica desativado, assim, se estiver atr�s de um caminh�o, vai entrar aquela fuma�a desagrad�vel. J� o desemba�ador s� ligue quando o vidro estiver realmente emba�ado. Alguns minutos depois desligue. Isso prolonga a vida �til do desemba�ador traseiro.
O ar-condicionado possui varias faixas de temperatura, o consumo de combust�vel aumenta quando este est� na posi��o frio m�ximo e diminui quando est� no frio m�nimo ou m�dio?
- Reginaldo Raposo
O uso do ar-condicionado aumenta sim o consumo de combust�vel, mas o compressor do ar-condicionado dos carros funciona de forma constante, de modo que, independente da velocidade escolhida, o consumo de combust�vel ser� o mesmo.

2009 Aston Martin LeMans LMP1 Race Car
In conjunction with the 50th anniversary of its only overall win in the Franco Enduro, Aston Martin is set to tackle the 2009 24-hours of Le Mans in this - a pair of Gulf liveried LMP1 race cars.
Racing the cars will be Jan Charouz, Tomas Enge and Stefan Mucke along with Darren Turner who was part of the team that raced the DBR9 GT1 crew in 2007 and 2008. Harold Primat is the newest addition to the team and one other driver will be announced shortly. Unfortunately, Aston won�t be campaigning in the GT1 class in bid to focus all its efforts on its LM
The new car which is based on the 2008 Charouz Racing System Lola will be powered by the same production-based Aston Martin V12 engine which, last year, helped Aston Martin secure its second successive Le Mans GT1 title with the DBR9. It also powered the Charouz car to a new La Sarthe lap record for a petrol car.
Aston Martin Racing is developing the car in conjunction with Lola, Michelin, Koni and BBS and continues its relationship with major partner Gulf Oil and official clothing partner Hackett.
In 2009, the ACO is introducing new regulations aimed at balancing the performance of petrol and diesel engined prototypes making the LMP1 category more appealing and relevant to Aston Martin.
To focus maximum energy on the LMP1 programme, the Works team will not defend its GT1 title at Le Mans. However, Aston Martin Racing will support any of its official partner teams and customers competing at the race.
The Le Mans 24 hour race will be held over the weekend of 13-14 June.

Ferrari SUV Launching Next Year?
A Ferrari SUV might take some getting used to. The idea to produce SUV actually has been around for some years and this is the freshest artist rendition. It�s an SUV by the definition of a vehicle with four doors, raised ride height, mostly fitted with a 4WD system and takes the shape of a station wagon/ tourer.
Ferrari give codename �Ferrari FS 599 Fuoristrada� .The SUV will be constructed out of aluminium and carbon fiber composites for weight-efficiency. Engines come from the naturally aspirated V8 found in the California and the 599 GTB�s V12 powerplant. They produce in excess of 400hp and 600hp each respectively.
Renderings of a Ferrari SUV have appeared before based on speculation that the Italian company was working on its first ever SUV. At the time Porsche was riding high with the great success of its Cayenne and premium brands like Mercedes-Benz and BMW had been building MLs and X5s for years before.
As the world's economy is still under recession, there�s no clear direction as to whether the project is still going ahead or not. However,with the recent announcement of an alliance with Ferrari parent Fiat and Chrysler LLC of America new possibilities have arisen. Such possibilities include a common SUV platform that can be shared with Jeep, Alfa Romeo and Ferrari itself. Product assembly could even be in the US just like Mercedes with the old ML and BMW with the X5 and X6.

Ford announces dual clutch PowerShift gearbox
The new gearbox will deliver the fuel efficiency of a manual gearbox with the convenience and ease of a premium automatic transmission,making it a key enabling technology as Ford targets best-in-class or among-the-best fuel economy with every new vehicle it introduces in North America.
Overall, Six-speed transmissions already have helped vehicles such as the 2010 Ford Fusion achieve best-in-class fuel economy, while at the same time allowing the Ford Flex and Ford Escape to achieve unsurpassed fuel economy in their respective segments.
Ford is leveraging six-speed transmissions, advanced internal combustion engines such as EcoBoost, hybrids, full electric vehicles, vehicle weight reduction and electric power-assisted steering to improve fuel economy and reduce greenhouse gas emissions fleet-wide by 30 percent by the year 2020.
Compared to traditional automatic four-speed transmissions, PowerShift can help reduce fuel consumption by up to 9 percent depending on the application.
PowerShift provides the full comfort of an automatic with a more sophisticated driving dynamic, thanks to uninterrupted torque from the dual-clutch technology, which consists essentially of two manual transmissions working in parallel, each with its own independent clutch unit. One clutch carries the uneven gears � 1, 3 and 5 � while the other the even gears � 2, 4 and 6. Subsequent gear changes are coordinated between both clutches as they engage and disengage for a seamless delivery of torque to the wheels.PowerShift, unlike conventional automatic transmissions, does not need the heavier torque converter or planetary gears. In addition, the dry-clutch derivative eliminates the need for the weighty pumps, hydraulic fluids, cooling lines and external coolers that wet clutch transmissions require. As a result, the dry-clutch PowerShift transmission can weigh nearly 30 pounds less than, for example, the four-speed automatic transmission featured on today's Ford Focus.
Differentiating PowerShift even further in terms of its customer appeal is its shift quality, launch feel and overall drive dynamic, which are all facilitated by an expert blend of Ford-exclusive electro-mechanical systems, software features, calibrations and controls. These unique driving features include:
� Neutral coast down � The clutches will disengage when the brakes are applied, improving coasting downshifts and clutch robustness as well as reducing parasitic losses for increased fuel economy.
� Precise clutch control in the form of a clutch slip to provide torsional damping of the engine vibration � This function improves noise, vibration and harshness (NVH) at low engine speeds and enables lower lugging limits for improved fuel economy.
� Low-speed driving or creep mode with integrated brake pressure � This function simulates the low-speed control drivers are accustomed to from an automatic transmission. The amount of rolling torque in Drive and Reverse is precisely controlled, gradually building as brake pressure is released.
� Hill mode or launch assist � Prevents a vehicle from rolling back on a grade by maintaining brake pressure until the engine delivers enough torque to move the vehicle up the hill, providing improved driver confidence, comfort, safety and clutch robustness.

Jaguar�s Reborn XJ220
According to our network of spies, the revolutionary sports car is being developed by the firm�s best engineers as a rival to the Audi R8. It�s based on an all-new aluminium chassis, which has been developed using the same know-how behind both the XJ and XK models.
The car will have aluminium panels stretched over an alloy and composite tub, while under the bonnet is likely to be a tuned version of the 503bhp 5.0-litre supercharged V8, set to power the eagerly anticipated XFR. A mildly modified version of this engine has already propelled a near-showroom-spec XFR to an incredible 225mph on the Bonneville salt flats in the US. The new supercar is likely to match this figure, while the sprint from 0-60mph should take less than four seconds.
The two-seater is tipped to be called the XE, and has been styled by a team led by Ian Callum.
Meanwhile,at the front, there�s an oval grille,framed by narrow, ultra-efficient LED headlamps. A steeply raked windscreen keeps the car�s overall height as low as possible, while the wide rear end supports buttress C-pillars, similar to those on the new Ferrari 599 GTB. As in the R8 and Ferrari�s F430, the engine will be visible through the rear windscreen.
Wide air intakes dominate the model�s front end, and deep scoops in the flanks help feed cooling air to the supercharged engine.CO2 emissions will be less than 300g/km, and the good things the powerplant will be capable of running on biofuel-blended petrol . Liberal use of lightweight materials, including aluminium and carbon fibre, will further improve the machine�s fuel efficiency and performance.
VW BlueRoadster Concept 2.0TDI
All these being achieved with frugality of a diesel powerplant returning 4.3l/100km, part of the fuel efficiency being aided by VW's superb 6-speed DSG gearbox.
Nothing official from VW at the 2009 Detroit Motor Show whether this will make it to showroom, but For Wheels reckon perhaps sometime in say, 2010? The concept shown above looks very much production ready, save for the dashboard and centre dash console. "Das Auto" it will be indeed if this does come true!

Bugatti Veyron 16.4
The 2008 Bugatti Veyron 16.4 is powered by by a mid-mounted and quad-turbo 8.0-liter W16 engine. Its 1,001 hp and 922 lb-ft of torque are delivered to all four wheels via a beefed-up seven-speed version of VW/Audi's excellent dual-clutch sequential gearbox (DSG). The transmission has two automatic modes , normal and Sport and may also be shifted manually via paddles on the steering wheel.
Published reports consistently have the Veyron hitting 60 mph from rest in under 3 seconds, and the car will attain extralegal velocities at a similarly dizzying rate. That 253-mph top speed must be enabled via a separate key, however; otherwise, the Veyron is limited to a mere 233 mph.
The 2008 Bugatti Veyron 16.4 is so fast that it needs an eponymous adjective. In a straight line, no other four wheeled conveyance can touch it. What's more, the Veyron's handling is nearly as impressive, no mean feat given its considerable heft. The only thing lacking and this is more of an esoteric issue is a lack of emotional involvement. Designed to perfection, the Veyron doesn't quite generate the visceral appeal that otherwise might come about in cars like the Ferrari F430 or Porsche 911 GT3 RS that take a more raw and hard-edged approach to performance.As one might expect in a $1.5 million car, the Veyron's cabin is pretty fancy. The leather upholstery is opulent and omnipresent, and extensive aluminum trim adorns the center stack, steering wheel and other controls. The gauge cluster features a somewhat gimmicky "power gauge" that supposedly displays real-time horsepower production. The Veyron's bathtub like high beltline, obtrusively thick A-pillars and low seating position don't bolster its credentials as a driver's car, but there's a lot of room in there, even for taller folks.
Captiva Ecotec 2.4 16V
A vers�o Ecotec 2.4 16V vem apenas com tra��o dianteira e cambio autom�tico de 4 marchas. No motor Ecotec os pist�es e cabe�ote s�o feitos de alum�nio e comando de v�lvulas vari�vel, ele tem 171 cv de potencia e 22,2 kgfm de torque (apesar de ter a mesma cilindrada do Vectra o motor n�o � o mesmo) e a GM diz que faz 10 km/l na cidade, o que eu acho muito dif�cil, mas se for verdade � uma boa marca.
A Captiva Ecotec continua a trazer de s�rie seis air bags, freios ABS e os controles de tra��o e estabilidade e agora todas as vers�es tem computador de bordo e um novo limite eletr�nico de velocidade com m�xima de 180 km/h, antes era de 160 km/h.

Um passeio com Nissan GT-R na neve
N�rburgring � um local com o tempo, digamos, n�o muito amig�vel onde neva muito e tem chuvas fortes com muita frequ�ncia e quando chove ningu�m se arrisca a entrar na pista. E n�o � todo piloto que se atreve a entrar nesta pista mas sempre tem um louco para entrar como o do v�deo abaixo.
EDAG Car Light Open-Source
O �Open-Source Car Light�, projetado pela EDAG, � uma amostra do que eles veem como o carro do futuro, o carro foi apresentado no Geneva Motor Show.
O prot�tipo � feito de fibra de vidro lastro (uma pedra vulc�nica muito comum) que oferece resist�ncia e economia. O mais interessante neste carro � que ele tem um sistema de ilumina��o feito por LEDs, onde o condutor pode escolher a quantidade e cores. Os LEDs s�o usados na parte interna e externa.

Peugeot 408 sedan
These are among the images of the new Peugeot 408 sedan lurking in the shadows showing a sleek sporty profile with large 5-spoke rims. The new peugeot model 408 will replace the current Peugeot 407 .The Peugeot 407 was launched since 2004 with several body variants such as a station wagon, a two-door coupe and a sedan.
The Peugeot 408 looks like to be ready on the road, begging the possibility of a Geneva Motor Show debut in this coming March. On the other hand it would be a surprise to see an all-new model since the 407 just received a minor facelift in 2008.
The current Peugeot 407 range has an assortment of engines including petrol and diesel.Peugeot 407 power up wit 1.8 litre petrol engine that can produce 114hp (85kW) and 1.6 HDi turbo diesels to the 2.7 HDi V6 making 201hp (150kW) and a sweet 440Nm of torque.
Peugeot could be preparing for a busy year. Recently the French manufacturer unveiled the new 3008 crossover while a 7 seater variant of the 3008 is coming soon.
Novo Fiat 500 PUR-O2
O motor usado no 500 Pur-O2 � o 1.2i 69 cv acoplado a uma transmiss�o manual de cinco velocidades. O desempenho de acordo com o modelo n�o iria alterar, no entanto, o consumo � reduzido em 0,3 l/100, permanecendo em 4,8 l/100 e um n�vel de emiss�es de 113 g / km de CO2.
O mais interessante � que para as altera��es e modifica��es a Fiat n�o vai cobrar nada, pelo menos na Alemanha, onde ser�o � venda nos pr�ximos dias por 13.000 �.

Celta VHCE j� � venda
A diferen�a na nomenclatura onde foi acrescido a letra �E� se deve �s novas regulamenta��es do Conama. A letra indica que o carro ficou mais econ�mico e menos poluente. O tanque tamb�m aumentou de 47,8 litros para 54l.
Para a vers�o Spirit, a Chevrolet incluiu mais itens de s�rie na carroceria de quatro portas. Agora o carro j� vem com vidros e travas el�tricos, alarme e terceira luz de freio. O pre�o ficou um pouco mais alto, partindo de R$ 26.447, R$ 84 a mais. Por fora, nada muda al�m do logotipo indicando o novo motor. As altera��es mec�nicas tamb�m ser�o estendidas ao sed� Classic, que deve chegar �s lojas em breve.
