800-HP Electric Bugatti Supercar Built, But May Never See Daylight

800-HP Electric Bugatti Supercar Built, But May Never See Daylight

Sneaking an 800-horsepower electric supercar onto the scene is a bit like sneaking an 800-pound gorilla into a dinner party. But that looks to be just what Bugatti has done, if the latest reports are to be believed.


Claims that Bugatti has already built a prototype 800-horsepower electric supercar are emerging out of Europe, though it has yet to be confirmed by outside eyes. In addition to the 800-horsepower, all-wheel output, the mythical Bugatti is thought to deliver a stunning 1,624 pound-feet of torque from 0 rpm.
It's not yet clear if that's actual crank torque, or wheel torque, as the infamous Audi R8 e-tron initially claimed a bountiful 3,319 pound-feet before it was revealed that the astronomic figure was produced after gear multiplication.

The battery-powered Bugatti promises "unbelievable" acceleration, according to the report, but discharges completely in just minutes--and we thought the regular Veyron was impractical.

It's not known if such a car will ever be built or if this development car is just a technology demonstrator. The problem with such a powerful car is range – or rather a lack of it. Power is the rate at which energy is converted. The more power you use, the faster the battery is depleted. In this case, full acceleration could drain the battery in just a few minutes, making it essentially useless. Fortunately, petroleum-powered Bugattis are built in such small numbers that their effect on the environment is absolutely negligible.

Tesla Model X

Tesla Model X Review


The Model X is Tesla’s follow-up vehicle to the award-winning Model S sedan. The X shares about 60 percent of the content from the sedan—converting the sleek Maserati-looking five-passenger model into a stylish crossover utility vehicle.
Performance:At the outset, Tesla is only taking orders and delivering for two Signature series models, the 90D and P90D performance edition. Both are all-wheel-drive configurations with the same battery pack, but the 90D has dual 259-horsepower motors in the front and rear, while the P90D boosts output for the back wheels to 503 horsepower, bringing total torque to 713 pound-feet.
The 90D will get you from zero to 60 mph in 4.8 seconds, while the P90D can do it in 3.8 seconds. Opting for the “Ludicrous Speed” upgrade cuts that time down to 3.2 seconds. Top speed for each of these models is 155 miles per hour.
Those who had the opportunity to take the Model X through a quarter-mile sprint report rollercoaster-like G-force sensations, the likes of which are rare in even the finest performance SUVs. In competing with the likes of Porsche, Tesla’s ace in the hole has always been electric vehicles’ capacity for instantaneous torque, which, if not governed to replicate a more natural acceleration rate, would make the Model X a very dangerous piece of machinery. Gasoline engine competitors could give the finest engineers in the world endless budgets to develop a better sprinter, but Tesla would always be able to beat them.
Air suspension with five settings enables the Model X to adjust from 9.5 inches of ground clearance to 6.5 inches, often automatically. In fact, you can even program the SUV to recognize certain spots—like a particularly worn down patch of road or a driveway entrance with a high lip—and adjust in anticipation of them without command.
The Model X is rated to tow up to 5,000 pounds, although the hitch necessary to do that will add an additional $750 to the price of the vehicle.
Styling:The Model X is Tesla’s follow-up vehicle to the award-winning Model S sedan. The X shares about 60 percent of the content from the sedan—converting the sleek Maserati-looking five-passenger model into a stylish crossover utility vehicle in the design spirit of the Acura ZDX or BMW 5 Series Gran Turismo.
Tesla wants to make cool cars that lure new waves of buyers to try an electric car. But it’s hard to make an SUV with minivan-like qualities look sexy. From certain angles, the X looks like a bulked-up taller S. That’s not a bad thing, considering the beautiful design DNA of the Tesla sedan—but the Model X is unlikely to be a head-turner like the Model S.
The first thing you might notice is that Tesla has opted to forgo anything resembling a faux grille. Perhaps afraid of looking too different from gasoline vehicles, electric carmakers have typically opted to include some sort of functionless patch of metallic material where a grille would normally be. Tesla was undaunted by the unfamiliarity of the front-end design.
The Model X has the same wheelbase as the S, but it’s about 2.3 inches longer, 4.4 inches wider and 10 inches taller. Amazingly, despite the extra height, the Model X is no less aerodynamic than the S, with a 0.24 drag coefficient.
The most notable design strategy for dressing up the Tesla SUV is the use of double-hinged falcon doors, which rise up and over the top of the car—rather than either opening like a regular sport ute or employing sliding like doors on a minivan. The advantage of falcon wing doors versus gull wing or even standard doors is their compact opening radius, extending less than 12 inches outward as they fold automatically above the car. The doors also give better access to the Model X’s third-row and make loading large objects like child safety seats in the rear passenger rows a lot easier.
The Model X also boasts the largest piece of curved glass ever used in a production vehicle. The sweeping windshield extends over the cockpit and doesn’t terminate until the B-pillar. This design eliminates the need for a moon roof (which the placement of the falcon wing doors prohibit.)
Inside, the Model X’s interior is a direct extension of the design cues Tesla established for the Model S. Controls for the typical luxury bells and whistles you’d expect to find scattered about the front console are all there, but you’ll have to scroll through the SUV’s gigantic 17-inch touchscreen to find them. Where most $100,000 luxury vehicles strive to present an air of classic regality, Tesla is selling science fiction come to life. It’s minimal, ergonomic and pristine—a design younger luxury buyers appreciate.
Tesla Model X
Passenger/Cargo Room:The Model X has redefined the possibilities for space and passenger comfort available from a long-range electric vehicle. How you choose to distribute that space is up to you.
The SUV comes standard with a five-seat configuration offering maximized rear cargo space for buyers who don’t do a lot of people hauling. For those who do, six- and seven-seat setups are available for $3,000 and $4,000 more respectively. In five- and seven-seaters, the second row is comprised of three individual captain’s chairs rather than a bench row. This has the effect of making the center seat every bit as supportive as the outer ones, and allows each passenger to adjust their seat independently. It also gives each seat a generous amount of storage space underneath.
Here’s where those dramatic falcon doors come in handy. The unique doors make stepping in and out of the Model X easier than a minivan, even in the third-row. The outer seats in the second row are independently adjustable as well, meaning that no more than one passenger will need to be disturbed when someone enters or exits the third row.
As with the Model S, the X doesn’t actually house any components where an engine would traditionally be found. Instead, Tesla provides additional storage space under the hood—enough for a few pieces of carry-on luggage or 4-5 shopping bags.
Critics say the Model X comfortably accommodates seven passengers, which is quite an achievement for a crossover SUV. The design of the seats themselves is one of the major areas of upgrade over the Model S, which many said didn’t live up to its price tag in terms of seat comfort. Upholstery is available in Black Leather, Tan Leather and Ultra White leatherette.

Charging:Tesla offers the most elegant and powerful charging system in the marketplace. It uses a 10 kW charger—a step above the 6.6 kilowatts or so commonly found in today’s electric cars. This means the Model X should be able to add 30 or more miles of range per hour of charging from a 240-volt source.
The big battery pack used in the Model X—as well as the Model S—makes this faster rate very useful for recharging all the way to full. Drivers will find they have plenty of energy reserves on a daily basis for common driving (regardless of charging rate).
Never content to offer just the best—rather than the crazy over-the-top absolute best—Tesla also offers a twin-charger that doubles the power rating to 20 kilowatts when combined with adequate amperage from home electricity service and Tesla’s High Power Wall Connector. In this configuration, you could pump in 60 or more miles of range in an hour of charging.
These scenarios all refer to home charging. But the cherry on top of the EV ice cream sundae is the free use of the Tesla Supercharger network, which enables all-electric road trips. The network—consisting of strategically placed 120-kW rapid chargers that can add as much as 170 miles of range in just 30 minutes—is a stroke of genius by Tesla.
There are currently more than 250 Supercharger installations in the U.S., and according to the company, 98 percent of the US population is now within range of the network. Consult with the Tesla website to see the current layout of Superchargers in your region.

Mercedes S550 Plug-in Hybrid Review

Mercedes S550 Plug-in Hybrid Review



It's hard to find flaws in a Mercedes S-Class. In the past, power and comfort came at some price in terms of fuel efficiency. With the S550 Plug-in Hybrid, you get all the benefits of the Mercedes flagship sedan, but now with 20 miles of all-electric range and (depending on how you drive and charge) as much as 40 miles per gallon.

Performance:The powertrain is comprised of a gas-powered 329-horsepower V-6 engine and an 85-kilowatt electric motor (pulling juice from an 8.7 kilowatt-hour battery)—all integrated with a Mercedes seven-speed automatic transmission. Put that together for 436 horses worth of oomph. Zero-to-60 mph acceleration time is 5.2 seconds, according to Mercedes.
The battery’s pack energy storage, of which 6.4 kWh is usable, means up to 20 miles of all-electric driving, if traveling below 87 mph. After those electric miles, the capable V-6 is put to use, with a top speed governed at 130 mph. A haptic kick down-like mechanism on the accelerator pedal helps drivers maintain electric mode, and otherwise drive with maximum efficiency—or consciously decide to push into the pedal for more power.
Four different modes allow drivers to decide emphasize when to use or save the battery’s energy. Or you can simply allow the computer to make the decision. Those decisions are probably smarter than your own—especially when using the S-50’s navigation system. That’s because the navigation, along with radar guidance, will use data about hills, valleys and other topography to calculate the best mode for optimized performance, energy regenerative and overall efficiency.
Reviewers who drove a pre-production model are divided handling—due to extra weight from the battery pack. Some say the S550 plug-in hybrid handles exactly like the gas version, while others believe the extra 650 pounds makes the car less adept at cornering. While that point is debatable, there’s no doubt that the V-6, even with the electric boost, is not as speedy and smooth as the non-plug S550’s 4.7-liter V8. The same concerns were expressed about the regenerative braking, which to some felt different than traditional brakes. Others, such as Road and Track, say that Mercedes is among the first automakers to “get regenerative brakes done right” and that it’s “natural and almost entirely seamless.”
Mercedes S550 Plug-in Hybrid
Charging:There’s nothing unusual about the S550’s charging process. If the pack is completely depleted, you can fully replenish it in about two hours from a 240-volt charging station. Or if you choose to use a standard 120-volt outlet, expect a charging time closer to four or five hours. That’s easily accomplished by plugging in every night. Still, it’s nice to be able to come home for a quick pit stop to maintain more all-electric driving—so a home 240-volt charging station is recommended.
The investment in a good home charging setup will come in handy for future possible electric cars with bigger batteries. At some point, you might want an all-electric BMW, Mercedes or Tesla as a garage mate to your plug-in S-Class.

Hyundai Ioniq 2017 to have lifetime battery-failure warranty

2017 Hyundai Ioniq to have lifetime battery-failure warranty


2017 Hyundai Ioniq Electric

Hyundai is extending the lifetime battery warranty offered on previous electrified models to the 2017 Ioniq lineup as well.
The warranty applies to all versions of Hyundai's first dedicated green car, including the Ioniq Hybrid, Ioniq Electric, and Ioniq Plug-In Hybrid.
As with previous Hyundai models, the warranty applies to complete failure of the lithium-ion battery packs in these vehicles, not to any degradation in battery capacity that may occur over time.

If the battery pack fails, Hyundai will replace it free of charge and "cover recycling costs for the old battery free of charge to the original owner," according to a promotional e-mail sent to customers.
The warranty does not cover vehicles placed in commercial service, which the e-mail defines as "taxi, route delivery, rental, etc."
Hyundai has offered its lifetime battery warranty since 2012, when it was introduced for the first-generation Sonata Hybrid midsize sedan.

Like any other component of a car, it is possible that battery packs can fail unexpectedly before the anticipated end of their service lives.
But batteries also degrade and lose some usable capacity over time, presenting a less straightforward issue for automakers seeking to reassure customers with warranty coverage.
While the Hyundai lifetime warranty does not cover battery-capacity degradation, a few automakers do offer coverage for this.

In 2012, Nissan expanded the warranty for its Leaf to cover certain amounts of capacity loss over the first five years or 60,000 miles of a car's life.
This was instituted after complaints and a lawsuit from Arizona owners alleging that Leaf electric cars lost battery capacity much faster than Nissan had indicated in the state's hot climate.
Nissan updated the Leaf battery pack in 2015 with a new and more heat-tolerant chemistry.

2017 Hyundai Ioniq

A settlement with Arizona owners announced in 2015 included replacement of batterypacks in 2011 and 2012 Leaf electric cars with these newer versions.
General Motors includes an eight-year, 100,000-mile warranty for the 2017 Chevrolet Bolt EV battery pack.

In the car's owner's manual, GM notes that the battery may degrade anywhere from 10 to 40 percent during that period.
However, the automaker believes a 40-percent reduction in capacity in regular use is highly unlikely (and most owners and analysts agree).
