FIA says FRIC no to trick suspensions in F1


Pastor Maldonado's Lotus at the 2014 Monaco Grand Prix


There are few fields in the world where you'll find engineers working as feverishly as they do in Formula One. With races sometimes won and lost by fractions of a second, every little bit counts, so each team retains legions of engineers, all dedicated to finding the tiniest performance edge... without running afoul of the ever-constricting regulations.

This season, one of the most controversial advances has been known as FRIC, and while it's been effectively sidelined for the last few races, reports from the motorsport press indicate that is has now officially been banned by the FIA.

So just what is FRIC? It stands for Front and Rear Inter-Connected suspension. Now, if you're thinking that independent suspensions are the most advanced form available, you're right, but F1 teams have been toying for years with ways to interlink the suspensions at each wheel. Why, you ask? For a number of reasons. For one, it allows for redistribution of suspension dive at the front or rear, which means that under hard braking or acceleration – when the car would either pitch back or forward – the car can be kept more stable. That, in turn, means not only are all four tires loaded evenly and optimally, but the team can also run a more aggressive aero package. It also means that the car can be set up with a softer suspension, allowing the driver to attack the curbs more aggressively, without sacrificing underbody aerodynamics.

Several teams had been running FRIC systems that move hydraulic fluid between the front and rear suspensions, but voluntarily agreed to cease using them for the last two races at Hockenheim and Budapest. Now, the FIA, having apparently deemed FRIC an unfair advantage in contravention of the sporting regulations, has reportedly banned the system altogether. So while those cars may not be running on an even keel any more, at least they'll all be on an even playing field.

Xcar takes a closer look at the electrifying Renovo Coupe


Renovo Shelby electric car


Xcar Films went to Pebble Beach and gave ex-Intel engineer and Renovo Motors CEO Christopher Heiser a platform to talk about his new electric supercar based on the Shelby Daytona Coupe. The relevant nuggets: 500 horsepower and 1,000 pound-feet of torque from direct-drive twin sequential axial flux motors powered by a lithium-ion battery, 0 to 60 in 3.4 seconds, top speed over 120 mph, 2,500 pounds, $529,000 to purchase.

While Heiser spends almost six minutes talking about the car and what it means to him, almost all of it is information we already know. When he gets to the bits that perk our ears, like when the mentions of advanced technology and upgraded parts, he skips the details. After four years of having to drive it at night to keep the secret, we don't even get to see more of what's inside, much less a daytime run with the Xcar chaps.

So we'll look forward to the next installment. In the meantime, this one's another beautiful entry in the Xcar catalog.

2015 Chevy Corvette Z06 priced at $78,995


Chevy Corvette Z06


Want to get your hands on the most powerful vehicle GM has ever made? It may be time to call your bank manager, financial adviser and whoever else helps you get your monetary ducks in a row, because Chevy has now revealed pricing information for the new 2015 Corvette Z06.

Pricing starts at $78,995 for the coupe and $83,995 for the convertible. Both those figures include destination, but don't include things like tax, title, license and optional equipment. And as we revealed when the order guide surfaced, there is some enticing optional equipment on offer.

An extra $2,995 will get you the Carbon Fiber Ground Effects package with enhanced aero. $7,995 will get you the Z07 Performance Package with Brembo carbon-ceramic brakes, upgraded tires and even more aggressive aero. There are three trim levels available and a host of other packages and options you can read all about in the press release below, from the Premium Package leather trim to the Performance Data Recorder.

No matter which way you set it up, though, you're getting a 6.2-liter supercharged V8 with 650 horsepower and just as much torque. And though the price of entry may seem high, it comes down to a downright steal compared to the six figures Chevy got for the previous ZR1 (whose place the new Z06 effectively takes) and which Dodge gets for a new Viper.

Volkswagen considering a four-door, four-seat XL1


Volkswagen XL1, front three-quarter view.

Posted Aug 22nd 2014 10:15AM


According to a report in Autocar, Volkswagen might have more in mind for the XL1 than mining it for advances to grace the next-generation Golf. Aiming to fight the Honda FCEV due for public consumption next year, we're told VW executives have put a four-door, four-seater version of the XL1 - it could be called XL2 - on the drawing board. The impetus is said to come from the top, with VW Group chairman Ferdinand Piëch intent on staying in the deep end of "super-efficent vehicles."

Autocar suspects the necessary changes could raise the weight of the car from 1,749 pounds to 2,068 pounds, which would make it four pounds less than the 2,072-pound Up! we drove a few years ago. Crucially, however, the mag thinks the extra capacity wouldn't change the two-seater's 310-mile-per-gallon rating, with tech tweaks and the aerodynamic benefit of a longer car offsetting the weight. Speculation is that the back seats would be staggered like the fronts in order to maintain the XL1's overall profile.

We recently heard about another XL1 variant that's gone off the radar entirely, the Ducati-engined XLR that we thought we'd see at the Geneva Motor Show and that was said to be going into production, so this one could go the same way. The biggest hurdle to making such an idea a reality, though, could be the price: the current XL1 costs 110,000 euros ($146,116). If VW really is going to compete with the Honda FCEV and the Toyota FCV - $70,000 in Japan - that might be where it wants to start.

2015 Chevy Corvette Z06 price and power compared against rivals


Ranking Z06 With Porsche, Ferrari, GT-R, Hellcat, Etc.

Posted Aug 22nd 2014 4:30PM



The 2015 Chevrolet Corvette Z06 is the most powerful production car ever from General Motors, and it's a technological landmark in the long lineage of Corvettes. It's also more affordable than you might think.

The 2015 Z06 starts at $78,995* – not chump change, but well below the price ranges of key competitors.
As was announced earlier today, the 2015 Z06 has a starting price of $78,995 for the coupe and $83,995 for the convertible, *including $995 in destination charges. That's not chump change, but it's well below the price ranges of several of its key competitors.

The Corvette has long been compared with the Porsche 911, but the Z06's 650 horsepower and 650 pound-feet of torque easily eclipses the most powerful 911, the Turbo S (560 hp, 516 lb-ft). The Z06 also costs less than half as much, as the Turbo S has a starting MSRP of $182,700, and then tacks on a $995-shipping charge.

A closer comparison – pricewise – would be the Porsche Cayman GTS, which comes in with an MSRP of $75,200 – that's $2,800 cheaper than the Vette. Thing is, it has 310 fewer hp.

The Audi R8 is a slightly more formidable competitor to the Z06 based on pure power. The V10 Plus has 550 hp, and its mid-engine configuration is a better layout for pure driving dynamics. But, its pricing starts at $173,500, not including a $1,250-destination charge. The base R8 with its 430-hp V8 begins at $115,000.





Then there's another long-running Corvette rival, the Dodge Viper SRT, and its 640-hp V10 engine. For 2014, the Viper costs $99,885, which is up $2,000 from 2013. Add in $1,995 shipping (your Viper does come in an enclosed trailer), and the total comes to $101,880. The price listed on the SRT website is $102,485, which includes the gas-guzzler tax, but not shipping. Regardless, it's about $22,000 more than the new Z06.

The all-wheel-drive Nissan GT-R, meanwhile, dials up 545 hp from a turbo V6 for $101,770, which rises to $103,365 with shipping.

The Z06 also grades out well in the world of exotics. The Ferrari FF produces 651 hp from its V12, which edges out the Z06 (barely), though the Ferrari only makes 504 lb-ft – all for a sticker of about $300,000 – though it does offer all-wheel drive.

Flipping the script on the Z06, the 2015 Dodge Challenger SRT Hellcat pumps out 707 horses for a price tag of $59,995 and a $995 destination charge brings the sticker to $60,990. That's more power for less money than the Corvette, but the Challenger is also a much larger car, and it's more of a muscle car than a sports car.

In this age of gaudy horsepower figures and prices, the Hellcat vs. Z06 is a fitting example of how modern sports cars are not all created equal. While the Hellcat can blow the doors off of the Vette with its power specs, the Z06 is assuredly a better track car. Porsche and Ferrari loyalists will naturally gravitate to and pay more for products from their brands, and no horsepower figure or "low-low" sticker price will change that. Plus, the sports-car segment is small enough in terms of sales so as to seemingly play by its own rules. No matter how much horsepower the Corvette has, it won't do much to erode GM's Corporate Average Fuel Economy standing.

While the Hellcat can blow the doors off of the Vette with its statistics, the Z06 is assuredly a better track car.
Still, the Z06 creates a seriously compelling value case for enthusiasts in search of power for a competitive price. Corvette spokesman Monte Doran reminded Autoblog that sharing parts and technology among Chevy vehicles has allowed the brand to keep prices of its high-end sports cars relatively low. The 2015 Chevy Corvette Z06 is the first Z06 to use a supercharged engine, the first to have a true convertible variant and the first to offer an eight-speed automatic transmission.

"Chevrolet has developed a successful model for sharing components with Corvette and other models in the portfolio," he said. "For example, the eight-speed transmission was designed for Z06, and will also be used in full-size trucks with the 6.2L; the carbon-ceramic brakes are shared between the Camaro Z/28 and Corvette Z06. This enables Chevrolet to offer stratospheric-levels of performance without stratospheric prices."

Dave Sullivan, manager of product analysis for AutoPacific, an automotive research firm, concurs:

"By sharing parts and components with higher-volume vehicles, GM can keep the price down on the Corvette," he said. "The Z06 could prove to be one of the memorable bargains of the century."

Sullivan expects the horsepower wars to continue, which is only good for enthusiasts.

"Look at the Ford GT a decade ago," he said. "It was about $150,000 for 550 HP and 0-60 in 3.7 seconds. For a little more than half that, you can get more power, better performance, and a car that the manufacturer is committed to building for many years to come. Inflation? What inflation?"
