Tesla unveils Model X car with Falcon Wing doors

Tesla unveils Model X car with Falcon Wing doors



Electric car-maker Tesla has launched its long-awaited Model X, which has a "bio-weapon defence" system and double-hinged doors that open upwards.
It is the third vehicle produced by the firm, and was unveiled nearly two years later than originally planned.
The firm - which has yet to make a full year profit - said about 25,000 people had pre-ordered the car.
Analysts say the Model X should be a success because it will be seen as a status symbol.


"I think we got a little carried away with the X," acknowledged Tesla's chief executive Elon Musk at the launch in Fremont, California.
"There is far more there than is really necessary to sell a car.
"And some of the things are so difficult, they make the car better but the difficulty of engineering those parts is so high."
One expert suggested the model filled a gap in the market.
"If Tesla's going to be a more significant player, they need more products and SUVs are what the market is demanding," said Michelle Krebs, a senior analyst at the car buying site AutoTrader.com.

Falcon wings

The sports utility vehicle (SUV) can fit seven people at a time.
Its "falcon-wing" doors open upwards and use sensors to help them clear obstacles, such as garage ceilings. The company suggests this will make it easier to put young children in car seats without hitting their heads on the roof.
The biohazard button activates the air filtration system, which fills the cabin with "medical-grade air".

The Model X also features a panoramic windshield that extends overhead, which Mr Musk said was the largest single piece of glass ever used in a car.
Tesla says the vehicle, which has two electric motors, can travel about 250 miles (400 km) on a single charge and features automatic functions that bring it "ever closer to autonomous operation".

It will be continuously improved, Tesla says, via software transmitted "over the air".
An update expected within the next month should enable an auto-pilot function, allowing the cars to be driven hands-free on motorways.
The Model X is priced as high as $144,000 (£95,000, €128,000), and Tesla expects the pre-orders will take between eight months and a year to fulfil.
The company has not disclosed pricing for the base model, but Mr Musk said that in the future there would be a "lower-cost" version.



Analysis: Theo Leggett, Auto industry reporter

For Tesla, it's vital the Model X is a success. But the company may already have left an indelible mark on the motor industry.
The vehicle looks a bit Back to the Future, but there's little that's retro about it.
It comes equipped with a range of hi-tech gizmos, not least radar and sonar systems to enable what the company calls "advanced autopilot features".
It's a crossover SUV, which is what upmarket consumers seem to be looking for these days, particularly in the US.
Clearly, Tesla wants to boost its sales. And it needs to - it's still racking up losses. But the company has already proved its point.
It has shown that electric cars can be fast, have a decent range and look, well, quite sexy.
At the recent Frankfurt Motor Show, both Audi and Porsche unveiled striking electric sports car concepts. They're not in production yet, but they do show what the carmakers think the future holds.
It seems Tesla has worried them.

Increased costs

The Model X is the third vehicle to unveiled by the company. Its first was the Roadster sports car - which is no longer in production, and its second the Model S saloon.
The firm has pledged to make its next vehicle - the Model 3 - lower cost. It is due to be revealed in 2017.
The company hopes to disrupt the car market by demonstrating that vehicles with electric motors do not need to compromise on speed or handling.


But it has yet to make a profit and its costs are mounting.
Its spending on fixed assets totalled $831.2m (£548.7m) over the first half of the year due to its investment in the Model X and Model 3 as well as a new battery factory in Nevada.
The Model X, Mr Musk said, "gives us a cashflow stream we can use to develop and facilitate" production and development.
In August, Musk said Tesla would make between 50,000 and 55,000 Model S and Model X vehicles this year, and would have the capacity to roll 1,600 to 1,800 vehicles off its production lines per week next year.

How To Be a Carb-Tuning Hero

How To Be a Carb-Tuning Hero


You'll need some electronics to do it, but now it's easier than ever to tune your carb like a pro.



In a time not long past there was that guy down the street from you--that special car-crafting guru who could tune an engine by ear. He was revered by the local gear heads for his uncanny knack for creating not just impressive power, but also for transforming chugging street slugs into razor-sharp sweetheart engines. He was like the Pinball Wizard--the deaf, dumb, and blind kid who could play those flipper fingers like he was part of the machine. We were all in awe of the Carb Wizard.

Float level can be used as a tuning tweaker for subtle changes to air / fuel ratio. Lowe is leaner and higher is richer.

While that guy still exists, we've discovered a little piece of electronic technology that can turn almost any knowledgeable car crafter in a Carb Wizard. This latest development in handheld electronic-power knowledge is the affordable air/fuel-ratio meter. While there are many on the market, we first told you about a favorite, the Innovate Motorsports digital unit, in "Tune In, Turn On, and Make Power" (Feb.'04) where we explain how it works alongside a few basics concerning air/fuel ratio and horsepower. This is such a potentially great tool that we thought we'd get into how to tune your engine using this tool not just for max power, but also to raise the bar for better part-throttle response and highway cruising. While the Innovate meter is capable of logging up to 44 minutes of brain-numbing data, we'll approach this tuning session assuming you're going to read the Innovate meter in real time. Ideally, data logging is better because you can study the information more closely.

WOT

The best place for wide-open throttle (WOT) air / fuel testing is at the drag strip. Short of that, you can do Second-gear bursts of 2 to 3 seconds each and have a passenger watch the meter. For your initial work, you should shoot for WOT air/fuel ratios between 12.5:1 to 13.0:1. Remember to make only one change at a time and keep using the same test procedure. If you're at the drag strip, use mph numbers to help with tuning trends. As long as your changes improve trap speed, continue to move in that direction. In many cases, the combination will berich--like 11.8:1 at WOT. That means you should start by leaning out the secondary side of the carburetor. With Holleys and Demons, minimum jet changes of two sizes per step are a good idea. For example, if you want to run leaner, go from 80 rear jets to 78s. It's also a good idea to start your tuning with the carb in its stock jetting configuration. If you are five or six jet sizes (or more) away from the box-stock configuration, it's possible there's something else wrong with the carb or your engine.

Part-Throttle Tuning


Contrary to what you may think, street engines spend a majority of time at idle and at very low throttle openings. In addition, the idle circuit continues to deliver fuel even when the carb is delivering fuel through the main metering circuit. Given this, the best place to start improving highway and in-town fuel mileage is with the idle circuit.
A high-speed lean condition can often be traced to low fuel pressure resulting from an under performing fuel pump.
Most general-purpose aftermarket performance carburetors are designed to deliver around a 12.5:1 air/fuel ratio to avoid lean surge conditions.Most mild street engines can tolerate part-throttle air/fuel ratios of 13.5:1 all the way up to as high as 15.0:1. Keep in mind that all production EFI engines operate at 14.7:1 air/fuel ratio and the drive ability is excellent. It's more of a challenge to tune a carburetor to achieve a lean 14.7:1 air/fuel at part-throttle and still deliver excellent and immediate WOT power, but it can be done. What this means is the power-valve and accelerator-pump circuits become much more critical. This is where a Q-jet shines, using its small, highly responsive primary side to achieve excellent throttle response for part-throttle driving. But other carbs can be tuned to also work very well. Don't be afraid of 14.0:1 or even 14.5-15.0:1 air/fuel ratios for part-throttle highway cruising. While these are lean ratios, they don't hurt the engine. There is very little load at highway cruise speeds because the engine is only making about 15 to 25 hp under these conditions.
This is definitely cut-and-try type work. If you go too lean on the idle-feed restrictors, the engine will surge at cruise and hesitate under light acceleration, since most engines don't like to accelerate at lean air/fuel ratios. If you tune the idle-feed restrictors too lean,the engine will most likely suffer from an off-idle lean stumble as a nearly indicator that you've gone too far. It's the transition circuits that are more seriously challenged and the ones that will falter first when you begin to lean out the idle and primary main circuits.
An ideal accelerator-pump shot is just enough to maximize acceleration.Additional fuel only kills power.

Tuning Challenge 1
Our first real-world example started out with a 9.0:1-compression 455ci Olds with a mild hydraulic cam, dual-plane Edelbrock, the stock 455Q-jet, headers, and an HEI ignition. The Innovate meter reported an idle mixture of around 12.0:1 that went lean at around 13.8:1 as the throttle opened up in mild acceleration. At steady-state highway cruise speeds,the air/ fuel ratio went back rich at around 12.5:1. At WOT, the engine was actually a bit lean.
The first thing we did was to adjust WOT tuning by swapping the stock CH secondary rods to thinner rods (eventually a pair of aluminum rods)until we had a WOT air/fuel that came in around 12.8:1. Because of the cam, intake, and header swap, part-throttle transition fuel was also slightly lean, so we changed to a slightly weaker power-valve spring to pull the metering rods out of the primary jets sooner as load increased.The engine responded with a slightly richer mixture in light acceleration of around 13.2:1, but we still had a slightly rich cruise air/fuel ratio. When we tried larger (leaner 52B) primary metering rods,it hurt light-throttle acceleration. Some late-model Q-jets are set up to allow you to adjust the position or depth of the primary metering rods in the jets. If our carb had been equipped with this feature, we could have adjusted the metering rods deeper in the primary jets to lean out the part-throttle metering.
Tuning Challenge 2
We also tried a 350 Chevy equipped with a long-duration cam and a Holley 750-cfm 0-3310 vacuum-secondary carb that suffered from a bad off-idle stumble and a pig-rich 10.5:1 ratio at part-throttle cruise. The WOT air / fuel ratio was only slightly rich at 12.2:1. The challenge was to improve the drive ability and mileage without sacrificing WOT power. After properly adjusting the primary accelerator-pump linkage, the stumble disappeared. We also replaced the large 0.035-inch accelerator-pump nozzle to a 0.028 to further improve the throttle response.
Setting idle mixture will change when you bolt on the air cleaner. If possible, set your idle-mixture ratios with the air cleaner in place.
The LM-1 meter told us the engine was way rich at just off idle, so we first tried leaning out the idle-mixture screws, but it didn't help. Next we disassembled the carb and found that a previous hacker had drilled out the idle-feed restrictors to 0.052 inch. Stock 750 Holley carbs come with idle-feed restriction of around 0.032 to 0.035 inch.Some quick math revealed that the 0.052-inch orifice increased the area by more than 100 percent. As a temporary fix, we tried a 0.020-inch-diameter wire stuffed into the idle-fuel jet to reduce the flow area. The larger wire reduced the area by roughly 15 percent, which leaned out the part-throttle air/fuel ratio to roughly 11.8:1, which was still very rich. Further experimenting with reducing the main jets from7 2 to 69 and using a slightly larger 0.025-inch wire in the idle-feed jet finally got the part-throttle air/fuel ratio close to 12.8:1. We could not tune any leaner without creating an off-idle stumble and part-throttle lean-surge condition because of the cam. The WOT air/fuel also improved with the leaner primary jetting to 12.5:1. These simple changes improved the fuel mileage by over 30 percent.

CC Tuning Tip

Poor ignition performance can be confusing when using the LM-1 air/fuel-ratio meter. When a cylinder misfires, the air and fuel do not combust, meaning the oxygen in the air moves into the exhaust where the O2 sensor will immediately pick up the additional air and indicate a lean condition. Simply put, this means a dead cylinder or occasional misfire will show up on the Innovate meter as a lean condition, not a rich mixture as you might think. Fix the misfiring cylinder(s) and the air/fuel ratio will read as a richer mixture. 

Recap: Tuning Carburetors

Shoot for WOT air/fuel ratios between 12.5:1 to 13.0:1.

Baked Double Chocolate Cake Doughnuts

Baked Double Chocolate Cake Doughnuts


Have you ever met anyone who doesn’t like doughnuts? Well, if you have, those people are called monsters and I wouldn’t get too close to them.


It’s some sort of weird doughnut week or National Doughnut Day. Whatever. I barely pay attention to days like that (except this time I did) because doughnuts are great for any day, not just one day out of a whole year, duh!




Despite my attitude, here I am participating, drinking the Kool-Aid, following the rules. But only because this day coincided which my craving to create a chocolate-y cake doughnut that felt dense, very rich, decadent and unlike most baked doughnuts. This baked doughnut is legit AF. I’m in love with it. If I was a lunatic, I would eat like five in a row but I can’t because I try to be a reasonable person in my life but sometimes i fail. I ate three.



A few weeks ago my friend texted me and told me that she mastered a cake doughnut. Of course, her iteration was deep-fried, as it should be.

But for us home cooks and bakers, frying is annoying. It’s like telling us to climb Mount Everest or “print out this document and sign it!” It’s a fete.

Deep-frying, for me, is only for special occasions or for when something cannot be baked under any circumstance. Like bomboloni or beignets or onion rings.

But doughnuts are ok baked. Especially when they’re like this.

The topping is chocolate-y too. It’s classic. It’ll make you want to reach for a glass of milk and turn on afterschool cartoons. It will make you miss being a kid when eating five doughnuts in a row was acceptable…and maybe should I say normal?




Baked Double Chocolate Cake Doughnuts
RATING: 5
PREP TIME: 15 MINUTES
COOK TIME: 12 MINUTES
TOTAL TIME: 27 MINUTES
YIELD: 6 DOUGHNUTS
Ingredients
    Chocolate-y Cake Doughnuts:
  • Cooking spray, for doughnut pan
  • 3/4 cup plus 2 tablespoons all-purpose flour
  • 3 tablespoons cocoa powder
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 3 tablespoons unsalted butter
  • 3 ounces dark chocolate chips (or chopped)
  • 1/2 teaspoon instant espresso powder
  • 1/2 cup light brown sugar
  • 1 large egg yolk
  • 1/2 cup buttermilk, shaken
  • 1 teaspoon vanilla extract
  • Chocolate Glaze & Sprinkles:
  • 2 cups powdered sugar
  • 1/2 cup cocoa powder
  • 1 teaspoon vanilla extract
  • 3 to 5 tablespoons milk or water
  • 1 teaspoon corn syrup (optional)
  • 3 tablespoons sprinkles of choice (you might need more, who knows!)
Directions
  1. Preheat your oven to 350 degrees F. Spray your doughnut pan with cooking spray and set aside. In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda and salt.
  2. In a medium saucepan, set over medium heat, add the butter. When melted, add the chocolate chips and espresso powder. Allow to stand and melt for a minute or two and then mix with a spatula until smooth. Turn the heat off and then stir in the sugar and egg yolk. Lastly, whisk in the buttermilk and vanilla extract.
  3. In one batch, add the wet ingredients to the dry and mix just until you no longer see any speckles of flour. Fill the doughnut pan half way. Transfer the doughnuts to the oven to bake for 12 to 15 minutes, until firm to the touch. Allow to cool in the doughnut pan for a minute or two and then run a butter knife along the outside, lifting them out of the pan with your fingers. Transfer them to a cooling rack while you make the frosting.
  4. Meanwhile, in a medium bowl, whisk together the powdered sugar, cocoa powder, vanilla extract and 2 tablespoons of milk. Add more milk or water, one tablespoon at a time, until it reaches a thick yet pourable consistency. If you like, you can add the corn syrup. This is not mandatory and was only used to give it that beautiful sheen—feel free to skip it! Dip the doughnuts, one at a time, into the frosting and place back on the cooling rack. Top with a liberal amount of sprinkles. Doughnuts will stay delicious for up to 3 days when kept in an airtight container.

Saudi blogger Raif Badawi awarded Sakharov human rights prize

Saudi blogger Raif Badawi, whose flogging sentence caused an outcry, has been awarded the European Parliament's Sakharov human rights prize.




Parliament President Martin Schulz urged Saudi King Salman "to free him, so he can accept the prize".

Mr Badawi was sentenced to 10 years in jail and 1,000 lashes in Saudi Arabia for "insulting Islam".
Earlier this month he also won the Pen Pinter Prize for championing free speech.
The Sakharov Prize for Freedom of Thought has been awarded by the European Parliament since 1988 to individuals or organisations for their contribution to the fight for human rights and democracy.

It is named after the Soviet scientist and dissident Andrei Sakharov.
Flogging postponed
Mr Badawi, author of the website Free Saudi Liberals, was convicted of insulting Islam in 2012 and fined £175,000.
He received the first 50 lashes of his sentence in January, but subsequent floggings have been postponed.
In June, Saudi Arabia's Supreme Court upheld the verdict despite a foreign outcry.
"This man, who is an extremely good man, an exemplary man, has had imposed on him one of the most gruesome penalties," Mr Schulz told a packed European Parliament assembly in Strasbourg, France.

"I call on the Saudi king to immediately free him. Relations depend on human rights being respected by our partners... they are not only not being respected but are being trodden underfoot."
Guy Verhofstadt, leader of the European Parliament's Liberal bloc, said: "The European Parliament has sent today a strong political and humanitarian message to Saudi Arabian authorities."
Mr Badawi's wife Ensaf Haidar, now living Canada with their children, said the award was a "message of hope and courage".
"I thank the European Parliament," she told AFP news agency.
Mr Badawi was one of three nominees for this year's prize along with assassinated Russian opposition leader Boris Nemtsov and the Venezuelan opposition movement Mesa de la Unidad Democratica.
Previous winners include Nelson Mandela, Myanmar activist Aung San Suu Kyi and Pakistani education campaigner Malala Yousafzai.

Watch 4 People Who Believe In Ghosts Visit An Abandoned Asylum In The Middle Of The Night

BuzzFeed convinced four of their most superstitious employees to go midnight ghost-hunting in the middle of the California desert at an abandoned building that has no address. We think one of the volunteers explains this mindset best when he exclaims, “This is a stupid f–king idea.”


The professionals involved in this project — a ghost hunting group called Amondella Paranormal — have explored such famous haunted landmarks as the Palmdale Abandoned Asylum, Rancho Camalos and Cobb Estate, a mansion property reportedly so filled with the paranormal it’s called the “Haunted Forest.”
After driving to the location for a very long time off marked roads, Amondella led the volunteers into the heart of the rumored asylum space, where they used something called a “spirit box” to communicate with souls on the other side — and that’s when they hear something. ðŸ˜±ðŸ˜±ðŸ˜±

Know Your Basic Car Care

Know Your Basic Car Care




Regular checks

It may seem intimidating, but basic care car is often simply a matter of popping open the hood and taking a look at the engine of your vehicle.

Some basic car care starts with examining the exterior. Check your tires at least every other week to make sure they are inflated properly. This should be an actual check with a tire pressure gauge, but you may also advantage from a visual check to make sure the tires appear equally and properly inflated.

  • body and bumper damage, which should be monitored for insurance purposes
  • leaking fluids underneath the vehicle, including oil, power and brake fluid, transmission or other fluid (air-conditioning may cause water to drip under a vehicle)
  • smoke in vehicle exhaust, aside from normal diesel emissions or startup fumes
  • engine or fluid warning lights, which should be promptly addressed before any further driving


Under the Hood

Of course, much of the day-to-day driving maintenance for your vehicle must occur with the hood opened and up, but that doesn't mean you have to be a mechanic. The most important things to monitor and check regularly include the following:

  • engine oil level and cleanliness
  • antifreeze/coolant level (never attempt to remove radiator cap while engine is hot or warm)
  • brake and power steering fluid levels
  • transmission fluid
  • belts


Changing the Oil

One of the most important things you can do to maintain your vehicle is to change the oil and oil filter regularly. Some mechanics recommend changing the oil every 2,000-3,000 miles, but you can safely drive further. However, you should be sure to change the oil of your vehicle, or have it changed, at least every 5,000, including a new filter.

Your oil should be relatively clean, but still have a dark color to it once it runs through your engine. You should regularly check your oil level, and maintain it between the minimum and maximum fill lines. This is why it is a good idea to have some motor oil with the vehicle so you will be able to add some if needed.

There are a variety of types of motor oil to choose from. Lighter weight oil, such as 5W-30, is typically better for colder temperatures, while heavier oil, such as 10W-40, is more suited to warmer temperatures and climates. If your vehicle smokes or uses a lot of oil, a heavier weight and synthetic blend motor oil is probably best.


Other Replacements and Maintenance

Other important components and parts of your vehicle and engine that need regular maintenance and infrequent replacement include the following:

  • air filter
  • headlight, turn signals, and brake lamps
  • spark plugs and cables
  • engine timing belt
  • windshield wipers
  • Most engine tuneups are either actual motor work, or electrical tuneups consisting of spark plug, cable, and distributor cap replacement.
