2011 10 most exciting concept cars

Posted by zhugy on Thursday, April 28, 2011


Jaguar C-X75
Jaguar caught the world's attention at the 2010 Paris Motor Show with the C-X75 concept. This sleek car was partly designed to celebrate Jaguar's 75th anniversary, but it also showcases innovative technologies. It is essentially an electric car, with motors driving each wheel. This arrangement allows for torque vectoring with precise power delivery designed to aid handling.

The wheel motors at draw electricity from a lithium ion battery pack, with that battery pack getting recharged from two micro gas turbines. Jaguar says this powertrain lets the C-X75 hit 62 mph in just 3.4 seconds and reach a total range of 560 miles.

Sadly, Jaguar is not likely to build this car, merely showing it off as a technology demonstration and celebration of its 75th anniversary.




Alfa Romeo 4C
The compact 4C unveiled at the 2011 Geneva auto show sports typical Alfa Romeo styling, with beautiful curves rising up from the hood of the car and continuing all the way to the rear. The 4C is Alfa Romeo's attempt at an efficient sports car, the model designation half that of the 8C Competizione. Alfa Romeo constructed the 4C's body out of carbon fiber, which helps keep overall weight down to 1,874 pounds.

Alfa Romeo hides the door latches in the air intakes, minimizing body disruption. The intakes feed air to the engine's turbocharger. The 4C is powered by a turbocharged 1.75-liter direct-injection four-cylinder engine, displayed supercar style under the back glass. The good news is that Alfa Romeo plans to actually build this car.




Nissan ESFlow
Also unveiled at the 2011 Geneva auto show was the Nissan ESFlow, an electric sports car. Although this electric sports car concept looks like a Z, it was built from the ground up for its electric power train. Lithium ion batteries are located over the front axle, while two electric motors drive the rear wheels, contributing to even weight balance. The headlights actually conceal charging points.

Nissan cites exciting performance figures for the ESFlow, such as 0 to 62 mph in under 5 seconds. Meanwhile, range is quoted at 150 miles. The two rear motors can vector torque across the rear wheels, making for better cornering.

Although Nissan hasn't announced plans to build a production version of the ESFlow, the electric powertrain developed for the Leaf opens up many possibilities.




BMW Vision ConnectedDrive
BMW's roadster concept, shown at Geneva, is really more about the electronics than traditional design or motive power. Vision ConnectedDrive integrates three driving modes, which BMW calls Safety, Infotainment, and Environment. Each state uses lighting effects to signal its presence. Orange signifies Safety, and is denoted here by the lighting effects in the hood, which direct the driver's attention to the road.

Although BMW de-emphasizes the car aspect of this concept, it serves as a possible future design direction for BMW's Z series of cars. The windshield flows into the hood, while humps behind the seats evoke classic racing cars. The electronics certainly show how BMW is looking at integrating driving modes with the car.




Nissan Ellure
Nissan attempts to "redefine the sedan" at the 2010 Los Angeles Auto Show with the Ellure concept. Nissan takes a kitchen sink approach to the Ellure's powertrain, matching a supercharged 2.5-liter four-cylinder with Intelligent Dual Clutch Control and a 25kWh electric motor with an Xtronic CVT sending power to the front wheels.

Rear-hinged rear doors give the Ellure a wide opening into the cabin. Accenting the cabin are red ambient lighting, piping, and trim. Nissan calls the colors of the interior palette "Molten Ice," "Molten Steel," and "Molten Gray."

Many of the Ellure's lines suggest a future look for the Maxima, but expect it to lose the funky doors and many of the other concept car elements.




Mercedes-Benz A-class concept
At the 2011 New York auto show, Mercedes-Benz showed off this concept, intended to preview the next generation of the A-class. The design mixes classic Mercedes-Benz elements, such as the large badge on the grille, and more outlandish features. For example, the grille is formed from an array of black stems topped with silver.

A more realistic aspect of this concept is the power train, a direct-injection turbocharged 2-liter four-cylinder making 210 horsepower. The transmission is a seven-speed dual-clutch gearbox, helping to maximize fuel economy. Along with being a look at the next generation A-class, this concept also shows Mercedes-Benz's interest in bringing that model to the U.S.




Kia Pop
Kia's Pop concept car, shown in Paris, runs on electricity and is about 9 feet long. With those dimensions, it would make a suitable city car. But the outlandish design suggests it is not something that will ever see production.

The cabin uses a single, curved bench seat intended for three passengers. The rear of the car shows an interesting idea for spreading out the taillights instead of having them in one casing.

The Pop is a whimsical concept, with Kia designers exploring themes of different ways to configure space in a car.




Hyundai HCD-12 Curb concept
At the 2011 Detroit auto show, Hyundai showed off its latest concept, the HCD-12 Curb, an on-roader that is built to handle beat-up city streets while treating the passengers to an interesting cabin tech package. The Curb is a very compact package, only about 4 inches longer than Hyundai's smallest Accent model.

Out back, the concept features an illuminated "Curb" logo that shines through one-way paint. There are no door handles; drivers simply swipe a touch panel to pop the doors. The Curb uses a powertrain not unlike the Hyundai Elantra and Veloster. A 1.6-liter gasoline engine mates with a DCT gearbox to help the Curb reach an estimated 40 mpg on the highway.

Hyundai has not announced plans to build a production version of the Curb, but the compact SUV segment is getting hot. Something like it may end up in Hyundai's model line-up.




Ford Vertrek
At the 2011 Detroit auto show, Ford rolled out the new Vertrek concept, a small SUV built on the company's C platform, which also supports the Focus and C-Max. The hood of the Vertrek bulges up, probably more than needed for the turbocharged direct injection 1.6-liter Ecoboost engine specified for the car. The trapezoidal grille is a newish design element for Ford, seen previously on the Fiesta.

Ford showcases its idle stop technology with the Vertrek, and although this is no hybrid, includes a regenerative braking system to keep the battery charged. This latter technology complements the former, due to the battery drain incurred during long traffic lights when the engine shuts itself down.

The Vertrek indicates the design direction for the new Ford Escape, which will be a radical change from the boxy car of past generations.




Volkswagen Bulli
Volkswagen enthusiasts will welcome the sight of a big-plate VW badge, made famous by its presence on the Type 2, or Microbus as it came to be known in the U.S. Unlike the rear-engine, rear-wheel-drive Type 2, the Bulli gets front-wheel drive from its front-mounted electric motor. Volkswagen claims impressive numbers for the concept, such as a 186-mile range and a 1-hour charging time. Volkswagen unveiled the Bulli at the 2011 Geneva auto show.

The Bulli's doors are hinged, similar to those on the Type 2. Later Volkswagen Microbuses would get sliding side doors. One area where the Bulli does not compete with the Type 2 is quantity of windows, which numbered up to 23 in the original vehicle.

Volkswagen has suggested it wants to make a production vehicle similar to the Bulli, possibly egged on by the success of its retro-Beetle.

2012 Chrysler 300 SRT8

Posted by zhugy on Wednesday, April 27, 2011





New for 2012 Chrysler 300 SRT8 is an Adaptive Damping Suspension (ADS) system that is tuned specifically for the Chrysler 300 SRT8 to offer a compliant and comfortable ride. Under the hood of the 2012 Chrysler 300 SRT8, the new 6.4-liter HEMI® V-8 makes its debut in the Chrysler brand product lineup delivering an estimated 465 horsepower and 465 lb.-ft. of torque, up 40 horsepower and 45 lb.-ft. over the 6.1-liter HEMI V-8 it replaces. Projected performance numbers include 0-60 mph acceleration in the high 4-second range; quarter mile in high 12 second range; 0-100-0 mph in less than 16 seconds, top speed of 175 mph and stopping power from 60-0 mph in 120 feet.

In addition, drivers can manually choose between “Auto” and “Sport” settings that quickly change the shock damping and harshness characteristics from everyday commuting to more spirited driving situations. The ADS system also uses a wide range of on-road and driver inputs – such as vehicle speed, steering angle, steering speed, brake torque, throttle position and lateral and vertical accelerations – to automatically tune the suspension for specific conditions when necessary.




The performance SRT-tuned, fully-hydraulic steering system also has been improved with a new, heavy-duty pump and revised gearing to give drivers more direct feel and on-center response. New seven-spoke, 20-inch lightweight forged aluminum wheels and available three- or four-season tires provide great looks with fun-to-drive performance and handling.

The all-new 2012 Chrysler 300 SRT8 features more than 70 advanced safety and security features, including standard Keyless Enter-N-Go and electronic stability control (ESC) with segment-exclusive Ready Alert Braking and Rain Brake Support safety features to improve overall vehicle handling and performance.

2011 Alfa Romeo 4C concept

2011 Alfa Romeo 4C concept

The compact 4C shows typical Alfa Romeo styling, with beautiful curves rising up from the hood of the car and continuing all the way to the rear. The 4C is Alfa Romeo's attempt at an efficient sports car, the model designation half that of the 8C Competizione. In concept form, the 4C shows very few body panel gaps, the whole front of the car seemingly molded as a single, solid piece. Alfa Romeo constructed the body out of carbon fiber, which helps keep overall weight down to 1,874 pounds.

At a little over 13 feet, the 4C is longer by about 8 inches than the Lotus Elise. Both cars employ lightweight materials and use a mid-engine layout. With 60 percent of its weight over the rear wheels, the 4C should handle well. Although a concept, these headlights are not inconceivable for a production car. The main light is a typical HID, while surrounding LEDs projected through translucent plastics are not far off from current LED running lights in cars.




Alfa Romeo hides the door latches in the air intakes, minimizing body disruption. The intakes feed air to the engine's turbocharger. The side mirrors show carbon-fiber trim and a strip with the colors of the Italian flag. The 150 is a little mysterious. Alfa Romeo did not say what it represents, but fans of the company probably have a good idea.

Side blinkers on the front fenders feature the words "Centro Stile Alfa Romeo," the name of Alfa Romeo's design studio. The front of the 4C features a quadrilateral suspension, while the rear uses MacPherson struts. LED tail lights puncture the carbon-fiber body form in the rear.

Supercar-style, the engine, a turbocharged 1.75-liter direct-injection four-cylinder, is visible under the rear glass. The engine box does not look well insulated from the cabin, so the engine will produce some audible clatter.

Toyota recalls more than 50,000 Tundra trucks

Posted by zhugy








Toyota Motor Sales today announced that it will conduct a voluntary safety recall on about 51,000 2011 Tundra trucks to inspect the rear drive shaft. The rear drive shaft in an estimated 0.05 percent of the vehicles may include a component (slip yoke) that could break because of improper casting during the foundry process. According to the Japanese automaker, there are no reports of accidents or injuries associated with this condition, and no other Lexus or Toyota vehicles are involved in the recall.

Toyota will inspect or replace the rear drive shaft for free. The inspection takes about 10 minutes, the company said. Owners of the involved vehicles will receive a letter advising them of the recall. Information regarding the recall is included on the Toyota Web site or by calling Toyota Customer Experience Center at 1-800-331-4331.

2012 Subaru Impreza gets more efficient

Posted by zhugy on Tuesday, April 26, 2011



2012 Subaru Impreza
The 2012 Subaru Impreza loses a few pounds and a few ponies as it continues its evolution from a quirky little car into an efficient midsize volume seller. The new design has been criticized for being bland, but the new front end retains a distinct Subaru grill and aesthetic. The profile, however, is rather anonymous.

Fuel efficiency
Under the hood is a new 2.0-liter boxer four-cylinder engine mated to a CVT. The new model now returns 27 city and 36 highway mpg making the 2012 Impreza "the most fuel-efficient gasoline engine all-wheel drive passenger car in America," according to Subaru.

Two AWD systems
The efficient CVT is an option, but a five-speed manual is the standard transmission. Shifting your own gears will cost you a few mpg in the city and on the highway. The two transmissions have unique AWD systems. The manual gets the viscous coupled Continuous AWD system that we're already familiar with. The CVT gets Active AWD with an electronically managed transfer clutch that helps it to achieve the high fuel economy numbers mentioned earlier.




The hatchback is back
We've seen the sedan variant, but the 2011 New York auto show is our first look at the five-door Impreza. Predictably, the hatch looks sportier than the four-door, thanks to its more visually pronounced rear fender flare.




Premium cabin tech
The vehicle's physical footprint has remained the same, but inside there is more cabin space, thanks to a revised wheelbase. The Impreza gets a new cabin tech package at the Premium trim level. Bluetooth hands-free calling and audio streaming are now standard, as are USB connectivity and iPod control.

Optional navigation
Also available is a new touch-screen navigation system with voice control, iTunes tagging, SMS text messaging capability, and XM Satellite Radio with NavTraffic.

More to come
Upcoming STI and WRX variants will likely feature wider bodies and more polarizing styling. We can hardly wait, but we're told that these hi-po variants may be upwards of a year away. Until then, STI and WRX models will continue to use the old Impreza chassis.

2011 Smart Electric Drive Passion Coupe

Posted by zhugy










2011 Smart Electric Drive Passion Coupe

The Smart coupe would appear to be an excellent platform for an electric car. The gasoline version weighs less than 2,000 pounds. But its small size works against it, limiting the size of the battery. Smart refitted the coupe with an electric drive, replacing the lower rear-mounted engine and gas tank with a 16.5 kWh lithium ion battery pack and 41 horsepower electric motor.

The battery is on the small side for a pure electric car, giving the Smart only 65 miles range in EPA testing. Smart also limited the top speed to 60 mph, which is slow for Interstates. Besides the electric drive system, the Smart Electric Drive is identical to a standard Smart coupe. It has drum brakes in the rear and disc brakes up front. The suspension leads to a rough ride because of the short wheelbase.

The battery pack does not impinge on the Smart's cargo space, which is unexpectedly large. The cabin layout is the same between both electric and gasoline Smart coupes. In both cars, the ignition lock is on the console, behind the shifter.

These two pod gauges show the battery charge state and power use. The power use gauge is important to monitor to determine driving efficiency. The shifter does not have a manual mode, like on the gasoline-powered car. It could be replaced by push buttons, as the drive mode is all electric. Similar to the standard Smart coupe, the head unit is a simple AM/FM radio that lacks even a CD player.
