V12 Engine with racing spirit


A V12 engine is a V engine with 12 cylinders mounted on the crankcase in two banks of six cylinders, usually at a 60° angle to each other, but in some cases at a wider or narrower angle, with all 12 pistons driving a common crankshaft.

Since each cylinder bank is essentially a straight-6, this configuration has perfect primary and secondary balance no matter which V angle is used and therefore needs no balance shafts. A V12 with two banks of six cylinders angled at 60°, 120°, or 180° from each other has even firing with power pulses delivered twice as often per revolution as, and is smoother than a straight-6 because there is always even positive net torque output with little variation. This allows for great refinement in a luxury car. In a racing car, the rotating parts can be made much lighter and thus more responsive, since there is no need to use counterweights on the crankshaft as is needed in a 90° V8 and less need for the inertial mass in a flywheel to smooth out the power delivery. In a large displacement, heavy-duty engine, a V12 can run slower than smaller engines, prolonging engine life.

The first V12 was manufactured as a Craig Dorwald by Ailsa Craig in May 1904. 23,000cc, 150 bhp at 1000 rpm. Commander May used it successfully in the American races 1908. Being a hot coil engine, water inevitably shorted the high tension and the engine regularly misfired. This was cured with the introduction of two magnetos from Sir Robert Bosch.


Auto racing


V12 engines used to be common in Formula One and endurance racing. Between 1965 and 1980, Ferrari, Weslake, Honda, BRM, Maserati, Matra, Alfa Romeo, Lamborghini and Tecno used 12-cylinder engines in Formula One, either V12 or Flat-12, but the Ford (Cosworth) V8 had a slightly better power-to-weight ratio and less fuel consumption, thus it was more successful despite being less powerful than the best V12s. During the same era, V12 engines were superior to V8s in endurance racing, reduced vibrations giving better reliability. In the 1990s, Renault V10 engines proved their superiority against the Ferrari and Honda V12s and the Ford V8. The last V12 engine in Formula One, was the Ferrari 044, in the Ferrari cars driven by Jean Alesi and Gerhard Berger in 1995.

At the Paris motor show 2006 Peugeot presented a new racing car, as well as a luxury saloon concept car, both called 908 and fitted with a V12 Diesel engine producing around or even surpassing 700 DIN HP. This took part in the 24 Hours of Le Mans 2007 race, with a podium finish and very competitive performance, coming in second place after the similarly-conceived Audi R10 TDI V12 Diesel originally developed for the 2006 season.

2009 Porsche 911 Carrera


2009 Porsche 911 Carrera 4: New Motor, New AWD System, Better Mileage
The 2009 Porsche 911 Carerra 4, and its higher-powered Carrera 4S sibling, offer the same engines as in the standard Porsche 911 Carrera and Carrera S, which are new for the 2009 model year.
Having the electronically controlled AWD system offered in 911 Carerra 4 and 4S on board addresses some of the issues that plague 911 owners, namely extreme instability in wet weather, and a steep learning curve where the 911 Carrera tends to break traction more easily than the driver intends it to.
While still retaining all the power of the standard 2009 911 Carerra and Carrerra S models, the AWD Carerra 4 models are easier to drive in all conditions, and feature wider rear fenders and tires for a more aggressive look.


Porsche Carrera 4 with Electronically Controlled All-Wheel Drive
[Porsche Press Release]
Stuttgart. Showing the dynamic attitude typical of the brand, Dr. Ing. h.c. F. Porsche AG, Stuttgart, are continuing the generation change of the 911 model series. Just a few weeks after the new 911s with classic rear-wheel drive, the all-wheel-drive versions Carrera 4 and Carrera 4S are now entering the market in both Coupé and Cabriolet guise.
A whole range of new technologies surrounding the engine, the transmission and drivetrain ensures an even higher standard of driving pleasure on much lower fuel consumption. Particularly the precision and fast response of the new, electronically controlled all-wheel drive offers an even more intense driving experience, above all in interaction with the likewise new flat-six engines with Direct Fuel Injection and the PDK Porsche Doppelkupplungsgetriebe or double-clutch gearbox available as an option.
The features and characteristics of the new engines speak for themselves: Depending on the model, the new all-wheel-drive Carrera offers up to 8.5 per cent more power, up to 12.9 per cent more fuel economy, and 15.4 per cent lower CO2 emissions. Specifically, output of the 3.6-litre power unit is up by 20 to 345 bhp (254 kW). At the same time a Carrera 4 Coupé with PDK, to take just one example, consumes a mere 10.1 litres of fuel per 100 kilometres, equal to 28.0 mpg imp. The improvements on the 911 Carrera 4S with its 3.8-litre power unit are equally significant, with maximum output up by 30 to 385 bhp (283 kW) on overall fuel consumption down in the case of Carrera 4S Cabriolet with PDK to 10.7 litres/100 km, equal to 26.4 mpg imp.
In the new generation of the Carrera 4 and Carrera 4S electronically controlled PTM Porsche Traction Management replaces the former all-wheel drive with its viscous multiple-plate clutch. This superior system developed for the 911 Turbo and modified for the Carrera models combines the driving pleasure so typical of Porsche with an even higher standard of driving stability, traction and agile handling further enhanced by the mechanical rear axle differential fitted as standard.
The new all-wheel-drive sports cars come with sporting manual transmission featuring six gears. As an alternative the new models are available with Porsche's new Doppelkupplungsgetriebe replacing the former Tiptronic S automatic converter transmission and offering an even faster gearshift on less fuel. The Doppelkupplungsgetriebe or double-clutch gearbox comes with seven gears shifting electrohydraulically without the slightest interruption of traction and pulling force.
The new generation of the 911 model series stands out clearly through the discreet but striking modification of the front end and new lights technology. The new Carrera models come in all cases with bi-xenon headlights and new LED daytime driving lights.
The newly designed rear light clusters also feature LED technology and for the first time Porsche offers Dynamic Bending Lights as an option. It almost goes without saying that all Carrera 4 models come as before with their muscular rear end 44 millimetres or 1.73" wider than on the two-wheel-drive versions. And a new reflector trim bar between the LED rear lights gives the typical rear end of the car even more dynamic character.
New PCM Porsche Communication Management with its touch-sensitive screen improves operation of the in some cases optional navigation, information and audio systems to an even higher standard. And a further important point is that PCM is now compatible with Bluetooth, USB and iPod requirements.

Ride Hard but Smartly becoz someone cares for you!




Summary:
On your motorcycle, your riding strategy, physical skills, and protective
gear—in that order—are what separate you from the ground. These are
the three degrees of separation.

Article:

On your motorcycle, your riding strategy, physical skills, and protective gear—in
that order—are what separate you from the ground. These are the three degrees
of separation. By themselves, each of the three degrees can save you.
Combined, they create a nearly impenetrable defense against the hazards
motorcyclists face every day.

Riding strategy is your first degree of separation, because mental skills, as you know, make up 90% of everyday riding. One hundred percent attention to your surroundings, accurate detection and perception of road hazards and risks, and sound judgment and decision making are the primary keys of a good riding strategy.

Attitude also plays a part. Taking responsibility for your own actions is easy, but because you, the motorcyclist, will more likely suffer bodily harm in the event of a crash, then you, the motorcyclist, must take responsibility for everyone else’s actions as well. This means being tuned into not only your self, your bike, and your environment, but also being aware of other drivers, correctly anticipating their behavior, and effectively avoiding hazards before they place you at risk. Ideally, a skilled rider avoids hazards before they even become hazards.

Physical skills are your second degree of separation. You acquire them through training and they require constant practice to keep them sharp. Though they make up only a small percentage of everyday riding, when you really need them, they instantly become 90% of your survival. When something breaks through your mental barrier (as any hazard worth its weight is prone to do), instinct, self-preservation, and adrenaline have to take over. At these moments, if your physical response isn’t the correct one, you’ll immediately need to rely on your third degree of separation: protective gear.

Protective riding gear is your backup in case your first two lines of defense crumble. When something finds its way past your first two barriers, what you’re wearing is all you have left. It’s technically a combination of the first and second degrees. Mentally, it falls under preparation. Physically, it protects you from the ravages of the pavement and the elements such as heat, wind, rain and cold that can affect your ability to (mentally, again) concentrate and operate the bike.

In theory, your mental strategy can protect you from everything. For those times when your brain can’t save you, your physical skills and ability to control your motorcycle are your backup plan. What your mind and skills can’t protect you from, your riding gear has to. Each degree of separation can stand on its own, but each is far more potent when combined with the others.

Let’s look at an example of the three degrees of separation:

Meet Veemax Vince. Vince loves his bike. He uses it for commuting, transportation, traveling, and recreation. He likes the way he looks on his bike. He likes the way it makes him feel.

Unfortunately, Vince doesn’t use a riding strategy, has never taken rider training, doesn’t practice anything, and doesn’t wear protective gear. He just likes to ride, but genuinely thinks he knows how to handle his bike. Besides, he’s ridden for two years without an accident. He knows what he’s doing. Right?

One day, Vince is on his way home from work. It’s 4:30, summer, the sun’s shining, and the traffic is typical for rush-hour. He’s wearing penny loafers, slacks, a shirt and tie, and sunglasses. He’s riding down Last Chance Avenue, an urban four-laner that has no median, stop lights every four blocks, and a 30 mph speed limit. There’s no parking on either side of the street, and gas stations, liquor stores, motels, and apartment buildings are spaced evenly apart. Vince is five minutes from work and five minutes from home.

Vince approaches a four-way intersection. He’s got the green light and he’s in the left lane. His plan (if you could call it that) is cruising straight on through at 30 mph. On the far right corner of the intersection is a convenience store. In the right lane, in front of the convenience store, is a big delivery truck, parked illegally, with its flashers on. The truck is blocking Vince’s view of the store’s exit.

The truck is also blocking the view of Sherry Cavalier, the woman trying to turn left out of the convenience store, behind the truck. She takes a slug of her Coke, sets it down, looks left and right, doesn’t see anyone coming, and pulls out—right in front of Vince. Vince’s eyes grow as big as saucers, and he panics. He grabs a big handful of front brake and stomps on the rear. Sherry suddenly sees Vince, her eyes grow as big as saucers, and she panics. She slams on her brakes and stops directly in his path.

Vince’s ride is over. He slides, both tires locked and smoking, into Sherry’s left-front fender at about 20 mph. He is thrown from his bike, and he vaults over Sherry’s hood and lands on the blacktop on his head and forearms.

Twenty minutes later, Vince is on his way to the hospital, in a coma, with a fractured skull, broken hand, broken wrist, and snapped collar bone. He’s got multiple lacerations on his arms and chest, and a heapin’of road rash. His bike is bent in half and lying in a pool of gas and oil. Sherry, after giving her tearful statement to the police, drives home with a bent front wheel and crushed fender, sipping the Coke she bought forty minutes ago. It’s still cold.

Was there something Vince could’ve done to prevent this? Yes. There were a number of things he could’ve done:

If he’d been using a riding strategy, he would’ve been more cautious riding through the intersection. He would’ve known the most dangerous place for a motorcyclist is an intersection. He might have slowed down, and covered his brakes and clutch to reduce his reaction time. He may have noticed the big blind spot created by the delivery truck, and slowed even more or adjusted his position to accommodate it.

If he’d taken rider training, he’d have known how to use his brakes properly, and possibly been able to stop, or slow his bike enough to avoid the crash with a quick swerve.

If he’d been wearing a helmet, gloves, and a jacket, he might have gotten up, dusted himself off, and spent the next ten minutes yelling at Sherry. Then he would’ve spent the rest of the afternoon mourning the loss of his beautiful bike.

Any one of the three degrees of separation probably would’ve changed the outcome dramatically in Vince’s favor. Had Vince been using all of them simultaneously, this accident likely never would have happened.

If you already use the three degrees, great. If you don’t, it’s time to start: If you don’t have a riding strategy, create one. If you have never taken a safety course, take one. And if you don’t wear protective gear, get some—the best you can afford.

But once you’ve done all that, is there nothing left? Do you just “stop learning” once you have the three degrees mastered? Of course not. Is it okay to be a “pretty good” rider instead of an expert? No way. Is there more to riding than just the three degrees? You bet. There’s a lot more.

The three degrees cannot protect you from everything—but they can protect you 99 percent of the time.
For ideas on how to protect yourself from the one percenters, try Ride Hard, Ride Smart—Ultimate Street
Strategies for Advanced Motorcyclists. In RH, RS, I use the three degrees of separation as a starting point to explore more advanced riding strategies: dealing with other drivers, choosing the safest route, vision and visibility, when not to ride, intersections, risk and hazard hierarchy, speed differential, shadowing, the soft lane change, understanding traffic flow, and group riding, among other concepts. As a bonus, there is an in-depth look at the Hurt Study, and what it means today.

Yamaha YZF R15 from the eye of motogeeeksatyam


Yamaha India is ready to make the Indian Biking scene more Hot with its new Bike getting ready for launch. Displayed at the Expo 2008 the bike looks more challenging. 150 cc and priced around Rs. 90,000 makes it more demanding in the market.



According to the Yamaha guys present there, this bike should soon make it into the Indian Market soon...

The Yamaha YZF-R15 sports a Full Fairing with Twin Headlamps, has a "Delta" Frame and a "Water Cooled" Engine, a Monoshock Rear suspension and a 6-Speed gearbox. I am not quite sure whether the YZF-R15 features Fuel Injection.





The specs that a Yamaha guy standing at the Yamaha Pavilion at the Auto Expo told the YZF-R15 was..

* Engine Capacity: 150 cc

* Maximum Power: 16 BHP

* Price: Rs. 90,000

The Yamaha YZF-R15 when launched is without doubt going to be the Best Looking Bike in India. The YZF-R15 is laden with all the features that any desi biker could ask for.

My only concern would be that this beauty deserves at least a 180 cc engine and should belt out at least 18 BHP to do justice to it's sports bike looks. 16 BHP would actually be a little dissappionting. and having a top speed of 145Km/hr awesome.

Lets wait for the Official Confirmation for the engine capacity and the BHP figures. But I salute Yamaha for not resorting to another half hearted attempt. This time the YZF-R15 definitely looks like a genuine and honest attempt..!!

TATA's GRANDE on hotspot with motogeeeksatyam


Do you have a bunch of kids to ferry to school each morning, especially ones who are always late? If so the Sumo may be a good choice. It has plenty of space and in Turbo form, packs quite a punch. However, it looks like a bread-box and is known to be suitable when fully loaded. Although, the external design changes add some visual flair to the boxy MUV.
