|Comparison of F1 engines… On Guitar!||
Some people can really get creative with their instruments, but this guy takes the cake!
In this video, the guitarist uses his electric guitar to imitate the different F1 engines; V6, V8 and V10.
In his description, he says that he wanted to make a prediction of how the new F1 engine specifications of the cars will affect their sound.
It is really quite amazing!

|2014 Cadillac CTS To Get Twin-Turbo V-6 Option||
If we had to sum up the new engine philosophy of automakers in a simple phrase, it would be “bigger is smaller,” or perhaps “less is more.” To reduce fuel consumption and lower emissions, automakers are turning to four-cylinder engines to replace six-cylinder power plants, and eyeing six-cylinder engines to take the place of V-8s.
While enthusiasts are quick to point out that “there’s no replacement for displacement,” the average buyer likely can’t tell the difference between a V-8 and a forced-induction six, except when it comes to his weekly spend on gasoline (where the V-6 has a decided advantage).
Even enthusiasts won’t be complaining about GM’s latest twin-turbo V-6 engine, set to launch in the 2014 Cadillac CTS sedan. It may only have a displacement of 3.6-liters, but at 118 horsepower per liter it’s the most powerful V-6 ever produced by General Motors. Peak output is rated at 420 horsepower and 430 pound feet of torque, which is good enough to get the 2014 Cadillac CTS sedan (which also boasts an eight-speed automatic transmission) from 0-60 mph in just 4.6 seconds.
In normally-aspirated form, a variant of this engine is already used in the Cadillac SRX, XTS and ATS. To handle the additional stresses of forced induction, the twin-turbo model gets a new block casting, new head castings, stronger connecting rods, domed pistons with friction-reducing skirts, a forged steel crankshaft and oil spray under the pistons.
To help the engine reach this impressive power density, it gets a 10.2:1 compression ratio, direct fuel injection, dual turbochargers and a charge air cooler (intercooler) system.
For now, GM says the new V-6 will appear in the Cadillac CTS and XTS models, but we hear it may be the engine of choice for the ATS-V as well. We wouldn’t be a bit surprised if it turned up under the hood of the next Camaro either, though muscle car fans amy have a hard time accepting the twin-turbo V-6 as an alternative to the V-8.
|Jaguar Launches Two New Engine Options In Beijing||
For those keeping score at home, we’ll make things simple: forced-induction six-cylinder engines are the new V-8s, and forced-induction fours are the new six cylinder engines. Need examples? Look at the EcoBoost V-6 offered by Ford in its F-150 pickup and Taurus SHO; from behind the wheel, they drive an awful lot like a V-8. As for turbocharged fours replacing sixes, BMW’s dropping of two cylinders in the latest 3-Series hasn’t hurt sales one bit.
The reasons why are easy to understand: smaller displacement engines are generally lighter, and under normal driving conditions return better fuel economy. Every single mainstream automaker, from Acura through Volkswagen, is doing all it can to increase fuel economy throughout its product mix. Luxury marque Jaguar is no exception to this rule, and it really was just a matter of time before it downsized engines, too.
Breaking cover that this week’s Beijing Auto Show are a pair of new Jaguar engines. The first is a supercharged 3.0-liter V-6 that will be available in versions rated at 375 horsepower (for use in the upcoming Jaguar F-Type roadster) and 335 horsepower (for use in XF and XJ models). The engine benefits from Jaguar’s extensive experience with supercharging, and comes with direct injection, dual independent cam timing, a compression ratio of 10.5:1 and sparkplugs that are oriented to maximize combustion efficiency. In 375 horsepower trim, the engine produces the highest specific output of any engine in the Jaguar range.
The automaker is also introducing a turbocharged 2.0-liter engine, rated at 237 horsepower, which will replace the normally aspirated V-6 used in the XF and XJ sedans. Like the bigger, supercharged V-6, the new forced-induction four will get direct injection and variable valve timing, and will rely on a low-inertia turbo to quickly build boost.
While Jaguar says that both engines are for “world markets”, it’s unlikely we’ll see the turbo 2.0-liter on these shores. In the U.S., the smallest engine currently offered in a Jaguar XF or XJ is the 5.0-liter V-8, which makes 385 horsepower. For now, at least, U.S. customers won’t be willing to accept a big cat that trades performance for fuel efficiency.
|Ford Working On A 177-Horsepower Triple: Report||
Automobiles with three cylinder engines have long been the butt of jokes among auto enthusiasts. Anyone who’s ever driven a Geo Metro, for example, knows that acceleration wasn’t one of the car’s strengths. It returned amazing fuel economy and offered a fair amount of practicality, but getting from point A to point B in a hurry wasn’t one of its strong points.
Even four-cylinder engines weren’t always enough to keep car guys amused, but automakers have now topped 100 horsepower per liter in normally aspirated engines. Throw some forced induction into the recipe, and suddenly the smaller and lighter engines have serious potential.
That’s Ford’s thinking behind its latest engine, a 1.0-liter, three-cylinder EcoBoost model that’s currently under development. Reports from Autocar, via Left Lane News, say that Ford is pushing to get 177-horsepower from the engine, courtesy of both an electric supercharger and a conventionally spun turbocharger.
While the performance variant probably wouldn’t be a mainstream engine, it could make an appearance in a Focus model slotted below the Focus ST, or in a higher-performance version of the subcompact Fiesta. In more pedestrian trim, Ford is planning on building some 1.3 million units of its three cylinder per year.
Ford is also rumored to be working on a 320 horsepower version of its 2.3-liter four, likely using a similar method of combined forced induction. When it comes to engines, it looks like sixes are the new eights, fours are the new sixes and triples are the new fours. Since less weight equals better handling, we’re good with this plan.
|2013 Cadillac ATS To Get Three Engine Options||
If you want more proof that Cadillac is serious about challenging the likes of BMW with its upcoming ATS sedan, here it is: the car will (initially) come with three engine options, including a 2.5-liter four cylinder that should serve as the base engine and will probably produce just short of 200 horsepower. Cadillac will offer a 3.6-liter V-6, too, probably pulled from the SRX crossover. In the 2012 SRX, the engine produces 308 horsepower and 265 pound-feet of torque, which should prove to be sufficient to power a compact sedan.
The big news, however, is a Cadillac-tuned 2.0-liter turbocharged four-cylinder, which will put out 270 horsepower and 260 pound-feet of torque. That’s 135 horsepower per liter, making the new engine one of the most power-dense motors on the planet. It achieves this via direct fuel injection, continuously variable valve timing and a twin-scroll turbocharger that produces up to 20 pounds of boost. That’s quite a bit for a stock engine from a luxury manufacturer, so Cadillac has built the engine to include a forged crankshaft and oil-spray piston cooling; they’ve also focused on reducing friction to produce more efficient power.
Suspiciously absent from the lineup is an ATS-V engine, which we’re hoping will come further down the line. Of the available choices, the turbo four is the one most attractive to drivers, since the V-6 will add weight and make the car nose-heavy without producing significantly more power. The 2.5-liter four will be the high-volume engine, sold to buyers who care more about luxury and comfort than about driving and performance.
Look for more details on the ATS when the car breaks cover at the 2012 Detroit Auto Show.
|Chrysler Working On Engine That Burns Gas And Diesel||
What if you could have the performance of a 4.0 liter V6, while returning the fuel economy of an inline four? Chyrsler is working with the Department of Energy on just such an engine, and it will use both gasoline and diesel to achieve these performance targets. It won’t burn the two fuels independently, so running out of gas (or diesel, presumably) will still leave you stranded. Instead, the engine burns the two fuels simultaneously to achieve both superior performance and fuel economy.
The engine is primarily a gas-burner that utilizes high compression and twin turbos to make reasonable power from a small displacement. Diesel is injected into the combustion chamber to control preignition, which allows the engine to run higher compression than pump gas normally allows. As a result, Chrysler claims comparable performance with a 25 percent improvement in fuel economy compared to their 2009 model year 4.0-liter V6. That translates into 31 mpg on the highway in a Town & Country minivan, but a smaller, lighter vehicle could see even bigger fuel economy improvements.
Chrysler isn’t the first automaker to undertake a multi-fuel engine project. Ford is working on a multi-fuel engine that uses both gasoline and ethanol, but there currently isn’t an infrastructure in place to support such a design in the real world. Where, exactly, would you buy ten gallons of ethanol? Diesel is commonly available from coast to coast, but both designs suffer from the same design drawback: multi-fuel engines require two separate fuel tanks and fuel systems, and they assume that drivers will never inadvertently mix fuels.
Since the engine is only in the design phase, Chrysler has time to sort out the bugs. I like the possibilities that such a design presents, because it shows that horsepower can coexist with fuel economy. Maybe the future for us horsepower junkies isn’t as bleak as we thought.

|2012 Camaro V6 Gets More Power, Better Fuel Economy||
For years, V-6 engines have been built the same way. The heads bolt to the engine block, and the exhaust manifolds bolt to the heads; the design has been proven for the past hundred years or so, so why mess with a good thing? Fortunately for us, the engineers working on Chevrolet’s V-6 engines aren’t satisfied with the status quo, so they’ve designed a better mousetrap. By casting the exhaust manifold into the aluminum head, Chevy’s engineer’s have managed to shed 12 parts per cylinder head and have shaved a total of 13 pounds off the weight of the finished engine. The net result is an increase from 28 mpg highway in 2011 to 30 mpg highway for the 2012 Camaro V-6.
But we enthusiasts care more about additional horsepower than a few more mpgs, and Chevy has delivered here as well. This year’s 3.6-liter V-6 gets larger intake valves (38.3 mm, vs. 36.9 mm) and 10 percent better exhaust flow than last year’s V-6, resulting in an increase of 11 horsepower. The 2012 Camaro V-6 is now rated at 323 horsepower, which gives it a clear advantage over Ford’s 305 horsepower V-6 in the Mustang (which, admittedly, is a lighter car than the Camaro).
By eliminating the conventional cast iron exhaust manifolds, Chevy was able to make the 2012 3.6-liter V-6 some 4.6 inches narrower, and they were able to move the catalytic converter closer to the exhaust point, which lowers emissions. It’s quieter at idle, too, but I’m not sure I’d brag about that to pony car buyers. Still, what’s not to like about more horsepower, less weight and better fuel efficiency?
|Building A Six Liter Ferrari V12||
Let’s be clear about one thing: you’re going to need a cigarette, a shower, and a few minutes for personal introspection after watching this video. It takes us where few have gone before, to a place more desirable than Scarlett Johansson’s bedroom. It takes us to the Ferrari factory, in Maranello, Italy, to witness the birth of a six-liter V12 engine. The engine in the video was produced for the now retired 612 Scaglietti, but that doesn’t make it any less wondrous. The video is an ode to hand craftsmanship, as each engine is assembled by a single
demigod technician, skilled in the art of extracting the maximum performance from aluminum and steel. The end result is an sensory masterpiece that puts out some 540 horsepower at 7,250 RPM, and sounds sweeter than a chorus of angels.
Since the end of 612 Scaglietti production in 2010, Ferrari is without a four-seat, hardtop grand tourer, but that may change as soon as the Geneva Auto Show in March. Whatever Ferrari creates to replace the 612 Scaglietti, you can rest assured it will be fast, it will be beautiful and it will use an engine every bit as sublime as the 6.0 liter in the video. Let’s hope they film the making of that engine, too.
|2012 Merc B-Class New Spy Photos Emerge||
New spy pictures of the 2012 Mercedes B-Class have emerged. The prototype has a strong resemblance to the BlueZero concept which debuted at the North American International Auto Show last year.
The 2012 Mercedes B-Class will be coming with a longer wheelbase, a Mercedes-Benz GLK-like grille, a panoramic glass sunroof and a tailgate-mounted spoiler. We also get a peek of the interior from one of the photos. But, unfortunately, we only get to see the rear seatbacks and the front armrest.
The new 2012 Mercedes-Benz B-Class will be sportiest yet as a high-performance AMG variant was confirmed by the tuning arm’s outgoing boss Volker Mornhinweg late last month. AMG currently offers V-8 engines, but for the B-Class a new specially tuned four-cylinder engine will be developed.
The current Mercedes-Benz B-Class has enjoyed reasonable success in most of the markets. But the next-generation model due in 2011 is expected to sell in even higher volumes.
|Hyundai RB Concept Revealed at Moscow Show (Video)||
Hyundai has introduced a new sub-compact family sedan concept RB at the 2010 Moscow International Motor Show. Production version of this concept car, which is basically a repackaged Verna / Accent, is scheduled to begin at Hyundai’s first full-cycle plant in Saint Petersburg, in January 2011. It will join the Hyundai lineup in the spring of 2011.
The car comes with redesigned bumpers, grille, hood and headlights. It will be powered by Hyundai’s new 1.6-liter or 1.4-liter Gamma petrol engines.
By replacing the old Alpha engine with Gamma, the sedan promises more power and torque, as well as best-in-class fuel economy. The estimated power and torque of 1.6 Gamma are respectively 124 PS and 156 Nm, while those of 1.4 Gamma are 107 PS and 135 Nm.
Both the engines will be mated to a four-speed automatic transmission or a standard five-speed manual transaxle. Watch the video below)
