| Mercedes’ Latest Video Shows The C63 AMG Coupe In Action Posted: 02 Aug 2011 06:04 AM PDT
As an automotive journalist, one of the most frequent questions I get is, "how can I get a job like yours?" On the surface, it does indeed look like a dream job: each and every week, I get a new four-wheeled toy to play with, complete with a full tank of gas. I work from a very comfortable office with a fifteen-second commute (twenty, if I stop for coffee on the way up the stairs), and occasionally manufacturers fly me to exotic places to drive their latest wares. They force me to eat good food and drink free beer, too, so the job does have its downfalls. When people ask me my dream job, now I have an answer: I want to be stunt driver Greg Tracy. When someone tosses me the keys to a press fleet car, the unwritten rule is "don't stack it, and don't shred the tires/brakes/clutch." They don't pay me to drive it either, but Tracy gets paid to both drive and use up things like tires, brakes and clutches. Here's the newest video from Mercedes-Benz, filmed at the request of a fan and featuring Greg Tracy. It stars two C63 AMG Sedans, which are really used as the world's most expensive traffic cones. It also features a C63 AMG Coupe, driven by Tracy, who drifts figure-eights around the sedans. There's no dialogue and no plot, but there's lots of tire smoke and the sense that the coupe was driven right to the tire shop for a set of new rear skins after filming. Next time someone asks me how to get a job as an automotive journalist, I’m going to look them straight in the eye and say, "Get me a job like stunt driver Greg Tracy, and I'll trade you."

| New Cafe Rules Not All Bad: Turbo Usage Expected To Triple Posted: 02 Aug 2011 05:55 AM PDT
 Turbos awaiting installation at Hyundai's Alabama plant. If you want to get substantially better fuel economy out of a car or truck, your options for doing so are somewhat limited. You can lighten the vehicle, but doing so is likely to reduce overall strength or substantially increase the price. You can add a hybrid drivetrain, but that adds weight, increases complexity and adds to the price. You can downsize the engine, but few drivers are willing to accept a significant reduction in power just to gain a few more mpgs. There's another choice, though, and it's one that's being rapidly embraced by manufacturers as the best and most cost-effective solution: downsize the engine, and then turbocharge it. In the old days, turbos had a questionable reputation for reliability. Formula One engines of the 1980's, for example, were small displacement, turbocharged four-cylinders that ran massive amounts of boost to create power. Calling these engines fragile is an understatement, and spectacular engine failures were common. Even on road cars, turbos often experienced bearing problems related to oil circulation, and engine failure was far more common than on less stressed, normally aspirated cars. Not so with the new generation of turbocharged cars. Ford's EcoBoost, for example, runs a modest amount of boost, but pumps the additional air into an engine that already has high compression and gasoline direct injection. High compression and turbocharging used to be a recipe for disaster, but today's knock-sensing technology makes such a setup possible. The end result is more power, plus better fuel economy, from a smaller displacement engine. Turbo and component supplier Honeywell sees the writing on the wall. Their vice president of engineering, Steve McKinley, summed it up by saying, "Engine downsizing coupled with turbos is the quickest way to make a significant improvement in the overall fuel efficiency of the U.S. automotive portfolio while maintaining performance levels." In other words, now would probably be a very good time to invest in Honeywell stock. GM agrees with this philosophy, too, and offers a 1.4-liter turbo option for their Cruze compact sedan. The upcoming Sonic will have a forced-induction engine choice, too, and don't be surprised to see turbocharged fours replacing V-6s and I-6s throughout many manufacturer's product lines. More power from less gas? What's not to like about that? Source: Left Lane News  |
| 2011 Chevrolet Corvette Z06 Review and Test Drive Posted: 02 Aug 2011 05:49 AM PDT
'SUPERCAR THRILLS WITH MONEY LEFT IN THE BANK' The 2011 Chevrolet Corvette Z06 is the world's only two-seat super sports car that costs less than $75,000.00 enabling you to save thousands of dollars to spend while enjoying the thrills of driving a true world-class supercar. I love Corvette's and this model is like no other on the market. With its racing-inspired powertrain and suspension features, along with an aluminum frame and carbon fiber fenders and floor panels, it delivers world-class levels of capability and automotive high-technology. With a curb weight of just 3,175lbs. it is the lightest, best-balanced Corvette model and one of the worlds most aggressively designed supercars on the market. It is a blast to drive and increases your heartbeat just looking at it. Indeed, racing is in the Corvette Z06's DNA and many owners' cars see double duty as daily drivers and weekend road course warriors. It's what the car was designed for and, compared to other sports cars that cost up to double-triple-or more, the Z06 offers competitive levels of performance at a lower price. Chevrolet brings significant updates to the Z06 for 2011, with special packages and new options that enhance performance and styling, while also offering great personalization choices: they include new standard Goodyear F1 Supercar Gen 2 tires and a returned dual exhaust system, new Z07 Performance Package, new CFZ Carbon Fiber Package, Z06 Carbon limited-edition model, two new exterior colors, Inferno Orange and Supersonic Blue (my test Z06), optional contrasting-color headlamps in Cyber Gray, Black or Blade Silver, new interior custom color stitching in red, blue or yellow, and a USB port and input jack included with the navigation radio. The Z07 Performance Package brings greater handling and braking capability to the Z06 with Brembo ceramic brakes, with gray metallic calipers, similar to those offered on the Corvette ZR1, Magnetic Ride Control, Michelin Pilot Sport 2 tires, twenty-spoke wheels in competition gray (19X10in. front, 20X12in. rear). The CFZ Carbon Fiber Package give the Z06 lightweight aero enhancements similar to those found on the ZR1, included in the optional package is a black-painted carbon fiber front splitter, rockers, roof panel and a body-color full-width rear spoiler. The Z06 Carbon limited-edition model blends the performance features of the Z07 package and the styling cues of the Carbon Fiber package. In addition to the features included with both new packages, this sinister-looking Z06 also includes a raised carbon fiber hood, black wheels, outside mirrors, and headlamp housings, a special engine cover, a leather and suede interior with body-color stitching, special graphics commemorating 50-years of Le Mans racing, and a special vehicle identification number sequence. The Z06 Carbon is designed to be the best Corvette for track events, with the chassis and aerodynamic features of the ZR1 complemented by the lower curb weight and balance of the naturally aspirated Z06's 427cu.in. V8 engine. Chevrolet will build no more than 500 examples of the Z06 Carbon; it is available in Supersonic Blue or Inferno Orange. My test Z06 came equipped with the new Supersonic Blue Metallic paint and the 3LZ premium equipment package that includes a custom leather wrapped interior, Bose Premium 7-speaker surround sound system, power telescopic leather wrapped steering wheel with buttons for the audio system and Bluetooth, heated seats, memory for two drivers, universal home remote, power adjustable sport bucket seats, luggage shade and cargo net. This nicely loaded Z06 kept me happy and thrilled on my rides around LA and through the canyons and mountains north ofMalibu. And away we go! The Corvette Z06 is powered by the LS7 7.0 liter, 427cu.in. V8 all-aluminum V8 engine that generates 505hp at 6,300rpm and 470lb.ft. of torque at 4,800rpm. Unique features include a racing-style dry-sump oiling system that helps ensure adequate oil pressuring during high-load cornering. The LS7 engine powers the 3,175 pound package to 0-60mph in a world-class 3.7 seconds in first gear, the ¼ mile in just 11.7 seconds at 125mph and to a top speed of 198mph. The Tremec TR6060 short-throw, smooth shifting manual is the only transmission offered with the engine. The Corvette Z06's powertrain and drivetrain are matched to the LS7's performance capability. The light, four-into-one headers discharge into close-coupled catalytic converters and through two-mode mufflers. The mufflers each feature a vacuum-actuated outlet valve, which controls exhaust noise during low-load operation but opens for maximum power. When you first push the dash-mounted start button you'll hear a loud blast of engine fire, then quiets down as you ease on the throttle and make you way down the road. It is quiet enough when just cruising at low to moderate speeds to enjoy the awesome Bose Surround Sound audio system. When you mash your foot down on the throttle for some 'pinned-to-the-back of the seat thrills, it gives out a monstrous engine growl that can be heard from two blocks away. Wow! What fun you'll have behind the wheel-cranking it up to hear the beautiful growl, you mild-mannered at conservative speeds. At the rear of the LS7 engine, a single-mass flywheel and lightweight, high-capacity clutch channel torque to the rear transaxle. The TR6060 six-speed manual is strengthened to handle the LS7's substantial torque load. It also incorporates a pump that sends transmission fluid to the front radiator for cooling. Upon its return, the fluid removes additional heat from the differential lube before returning to the transmission. The six-speed transmission connects to a limited-slip differential, with enlarged ring and pinion gears. Stronger axle half-shafts with tougher universal joints transmit power to the rear wheels. All of that power is wasted if the Z06 doesn't have a solid foundation and world-class suspension system to handle the forward power generated from the LS7 engine. It does and does it beautifully. The Z06 has an aluminum body structure for optimum stiffness and light weight for the fixed-roof body style. Perimeter rails are one-piece hydroformed aluminum members featuring cast suspension nodes, which replace many welded steel components on other Corvette models. Advanced structural composites featuring carbon-fiber are bonded to the aluminum structure. The wider front wheelhouses, for example, are carbon composites, and the passenger compartment floors combine carbon-fiber skins with an ultra-lightweight balsa wood core. The Z06 has a magnesium cradle that serves as the attachment point for the engine and some front suspension components. Magnesium is lighter than aluminum, yet incredibly strong. The magnesium cradle helps improve the front-to-rear weight distribution (50/50%), as do carbon-fiber front fenders and wheelhouses. Engineers also moved the battery from underhood to a position in the rear cargo area, behind one of the rear wheels and out of sight. The Z06 retains the 105.7 inch wheelbase of other Corvette models, as well as the short-long arm (double-wishbone) fully independent suspension and transverse leaf design but it has its own rear spring and roll stabilizer geometry as well as the cast aluminum upper and lower controls arms, and gas-charged monotube shock absorbers front and rear. The suspension is firmer than on a regular C6 Corvette and it works harmoniously with the new 19X9.5 inch cast-spun aluminum wheels and the new Goodyear 275/35ZR18 inch front and 19X12 inch cast-spun aluminum wheels with 325/30ZR19 inch F1 Supercar Gen 2 tires in the rear. With standard traction control, active handling and launch control the Z06 is incredible. It feels even more like you are glued to the road than using the term 'riding on rails'. In heavy load cornering, there wasn't even a squeal or shutter from the tires. They just hold you so tight around corners that you would normally slow down upon entering. I was amazed. For even more challenge you can shut the traction control system off and let the rear slide from under you to really slice through the curves. On the skid pan the Z06 pulls 1.0 g's. That's real racecar suspension power. You can feel the car move left or right with the slightest pull of the steering wheel. It is a thrilling ride you can't find in any amusement park! Complementing the world-class suspension system and large rolling stock is an equally capable world-class four-wheel disc brake system, consisting of 14 inch vented and cross-drilled front rotors and 13.4 inch vented and cross-drilled rear rotors. The front rotors are acted upon by large, red-painted six-piston calipers that use six individual brake pads. Individual brake pads are used because they deliver more equalized wear compared to what would otherwise be a pair of very long single-piece pads. The rear brakes use four-piston calipers with four individual brake pads. A four-channel ABS system is standard. From the engine to the 60-0mph 113 foot stopping power of the brakes, the Z06 is world-class sports car bliss in every respect. Also world-class and breathtaking is the aggressive, low and wide stance that is functional as it is attractive. The styling highlights include a wide front fascia with a large, forward-facing grille opening, a splitter along the bottom and wheel opening extensions along the sides to provide aerodynamic downforce, a cold-air scoop in front of the hood that integrated an air inlet system for the engine, a trailing edge of the front wheel opening that is radiused to achieve improved drag, but protects the body finish with a tough molding and a large air extractor bearing the Z06 logo, that is behind the wheel, the fixed-roof body style optimizes body rigidity and mass, shaved door handles improve aerodynamic drag, wide rear fenders with flares cover the massive rear tires and a brake cooling scoop in front of the wheels visually balances the fender extractor, a tall rear spoiler houses the CHMSL on the top of the rear fascia, ten-spoke spider-design aluminum wheels, and four large round stainless steel exhaust outlets are located under the bottom between the working diffuser. The aerodynamics of the Z06's exterior was shaped by the experiences of the Corvette racing program, where high-speed stability and cornering capability are paramount. While the race cars use large rear wings, the Z06's elevated spoiler provides sufficient downforce to balance the road-worthy front splitter without adversely affecting aerodynamic drag. For all of its race-inspired functionality, the 2011 Z06 is designed to be a daily-drivable, high-performance vehicle. To that end, comfort and convenience are held to a very high standard. Standard features not mentioned above include HID headlamps, foglamps, power-adjustable, leather-trimmed sport bucket seats, dual-zone climate control with air filtration, the original head's-up display with track and g-meter (unbelievable), power windows/power door locks, cruise-control, variable-speed wipers/washers/rear defroster, carbon-fiber bezel around the center stack and on the center console with dual cupholders under an accordion cover, a storage bin with padded armrest, carpeted floor mats, driver information center, power-remote/heated sideview mirrors, self-dimming rearview mirror, leather-wrapped steering wheel with buttons for the audio system/Bluetooth, remote trunk release/fuel door, power hatch pull down and an instrument cluster that is fantastic for its large, easy to read 7,000rpm tachometer, 200+mph speedometer, oil pressure/engine coolant temperature/volt meter/fuel gauges, all aluminum foot pedals, properly placed parking brake with brushed aluminum button, ergonomically designed leather/aluminum stick shifter, dual map lamps, dual vanity lighted mirrors, and storage in the glove box and door inserts. Standard safety features include front and side impact airbags, OnStar directions with automatic airbag deployment response, keyless entry with push button start/stop, and a theft deterrent system with alarm. The new 2011 Corvette Z06 has it all for supercar power and handling prowess in an aggressive and unique body style like no other supercar on the road. You can drive it every day and take it to the track on weekends. With all of these attributes you would think it is priced like other competitive world-class, two-seat sports cars that cost more than $200,000.00 but the Z06 is based priced at an unbelievable low $74,305.00 and my nicely loaded test model was stickered at just $81,775.00. Amazing, awesome and true!                  COPYRIGHT:2011:HARVEY SCHWARTZ SPECIFICATIONS

| Heading To Europe? Rent A Lotus Evora Through Hertz Posted: 01 Aug 2011 08:41 AM PDT
 The Lotus Evora, now available through Hertz. Image: Lotus Cars It's no secret that Europe has some of the best roads on the planet, and a business trip across the pond often requires you to rent a car to get from place to place. I've had good luck and bad luck with my own European car rental experiences, and usually wind up getting stuck with a station wagon. Sure, they're comfortable, but a quick run up the Stelvio Pass in a BMW 525 Estate isn't quite as much fun as the same drive in an Audi S4 or a BMW M3. You can't rent those cars (at least not easily), and the Europeans are probably wise to stick us under-trained American drivers in station wagons and subcompacts, just to keep us from dying on their roads. Hertz is looking out for us enthusiast drivers, however, and you'll soon be able to rent a Lotus Evora from select Hertz offices in France, Germany, Italy, Spain and the UK as part of their "Adrenaline Range" program. There isn't a lot of detail on requirements yet, but all drivers need to be age 30 or older, with two credit cards in their name. I tried to find pricing, but without any luck, and I can guarantee an Evora won't come cheap (or with unlimited mileage). Still, I can't think of a better car for a tour through Southern Germany, Austria and Northern Italy. The Evora will seat four (two comfortably), and there isn't a lot of room for luggage. That's offset by the Evora's light weight, sublime handling and Toyota-sourced V-6 good for 276 horsepower and 258 ft-lb of torque, which is good enough to get the car from zero to sixty in under five seconds. Pack light, bring a camera and make a list of 10 or 12 roads that you absolutely must drive, and the Evora could be your ticket to the vacation of a lifetime. Source: Lotus  |
| 54.5 MPG Is Coming, But What Does It Mean? Posted: 01 Aug 2011 07:47 AM PDT
 Image: dsb nola Last Friday, the Obama administration announced that a deal had been reached on new Corporate Average Fuel Economy Standards for cars and light trucks between 2017 and 2025. It was a mixed bag, with both the federal government and the automakers compromising to achieve results each side could live with. Even California, who reserves the right to set their own fuel economy and emission standards, bought into the new fleet-wide requirement of 54.5 mpg by 2025. If you're an enthusiast, it's easy to be alarmed by these numbers. By EPA ratings, not a single gasoline-powered vehicle achieves this today. In fact, only the Toyota Prius, at 51 mpg city and 48 mpg highway, comes close. Does this mean we're looking at a future of driving cars even less entertaining than the Prius? Are the golden days of muscle cars and sports cars behind us? Not necessarily, because buried in the new fuel economy standards are some exceptions that aren't well publicized. First, there isn't a direct parallel between a CAFE rating of 54.5 mpg and an EPA rating of 54.5 mpg. The CAFE rating is based on a complex series of variables, and the fuel economy standard is overstated compared to the EPA rating. I don't have a conversion chart, but understand this: 54.5 mpg under CAFE isn't 50 mpg under EPA, and it's probably not even 40 mpg. It may not even be 35 mpg. Next, there are "allowances" granted to automakers for being environmentally friendly. Opt to use a refrigerant that's environmentally friendly, and you get a credit that can be applied to lower your CAFE average. Build an electric car? That's another credit, even if you only sell a handful. Build a hybrid? That's another credit to lower your overall score. Using Ford as an example, the Focus Electric will offset the Mustang Shelby GT500, ensuring that both cars (or their equivalents) can still be found on the showroom floor. By 2025, cars will be more fuel efficient. They'll be lighter, with smaller and more efficient engines. Hybrids will be common, but that may turn out to be a good thing for sports car fans as hybrid technology goes more mainstream. Imagine a car with perfect weight distribution front to rear, that has AWD thanks to a standard drivetrain plus electric motors, and still gets better than 35 mpg. By 2025, I'd be willing to bet that performance hybrids are faster than today's muscle cars, for about the same kind of money. If that's really the future, I'm pretty sure I can live with 54.5 mpg.  |
