Tesla Reveals a Super Semi, 0-60 in Under 5 Seconds!

Leave a comment

At an event in Los Angeles on November 16th, 2017, Tesla unveiled its new Semi electric truck, which is capable of traveling 800 kilometers (500 miles) on a single charge with a loaded trailer.

Powered by four independent Model 3 motors, the vehicle can go from 0-60 mph in just five seconds; it’ll take 20 seconds while paired with an 80,000 pound load. The idea with the Semi is to create a shipping solution that’s not only more environmentally friendly than a diesel truck, but also more economical to own and operate.

The interior features a central cockpit for greater visibility and two large displays for navigation and other controls on either side of the cabin. The shatter-proof windshield uses Tesla Armor Glass that the company says is far more durable than standard glass; that’s a big deal because a cracked windshield takes time to replace, and it’s illegal to drive with a damaged one in the US, which means downtime and money down the drain for trucking companies.

In addition, the Semi beams data to a mobile app that presents vital information about the vehicle, along with remote diagnostics, preventative maintenance, and fleet management information.

With the Semi, the big draw for logistics companies will likely be the lower cost of ownership. Tesla says that a diesel truck is 20 percent more expensive to run per mile, and that running an Autopilot-powered convoy of Semis is even more economical than transporting cargo by rail, while also being 10 times safer than having the vehicles manned by human drivers.

It’ll be interesting to see if that’s enough to convince shipping companies to make the switch to Tesla’s electric offering. The Semi will begin production in 2019, and you can reserve them now by wiring across $5,000 apiece.

Chevy Bolt Or Tesla Model S, Which Is The Best EV For A Road Trip?

Leave a comment

Everyone loves a road trip: Driving through a region, discovering its magic, one mile at a time, while being as free as a bird to stop and sleep wherever you want to. It’s no wonder that road trips are an American symbol: They’re linked to a natural sense of freedom and exploration of vast landscapes that are so iconic of the US. But when it comes to road trips, it’s always the old Mustang or the long Cadillac that get in the picture of the perfect trip. Have you ever considered an electric car instead? We’re comparing the Tesla Model S and the Chevy Bolt to find out the best car for the exercise!

Chevy Bolt EV

The essentials on the road

Even though an electric car has a different fuelling system, it doesn’t mean that you shouldn’t pack like for a standard road trip, namely a box of tools to be able to change a flat tyre and cables to revive the battery. Admittedly, there’s no need to worry in case you’ve forgotten a tool or you find yourself unable to move the car. The tow truck service is equally available to fuel-powered and electric vehicles! But, you’ll enjoy the road trip more if you don’t need it!

Planning ahead

If it’s your first long drive with an EV, make sure to check a map of charging stations in the area before you leave. These are more difficult to find than fuel stations!

Tesla Model S: Supercharged in 30min

The Tesla Model S has some serious bragging rights, as with any electric car that allows you to invest in the future. But what is really exciting about this model is that you can in only 30 minutes get the car charged to complete a 170-mile-long journey, assuming you are using a Tesla Supercharger charging station. Remember the EV charging map? That’s why you need it! Additionally, the Tesla S is a fast car that can even beat the Ferrari 458 in a race.

Chevy Bolt: 313 miles on a charge

In comparison, the Chevy Bolt offers an impressive driving range on one charge: Up to 238 miles, although drivers claim to have managed 313 miles on a single charge. Unfortunately the Chevy Bolt can’t use the Tesla Supercharger, but you can use DC fast-charging stations to deliver 90 miles in the first 30 min. If you’re stopping in a hotel, it will take a 240-volt Level 2 charging station 9 hours to fill a discharged battery pack.

The verdict

According to EPA estimates, the 259 miles range of the Tesla Model S beats the Chevy Bolt, especially if you take into account the time of charge. However, recent tests by Consumer Reports show otherwise: The Chevy Bolt surpasses expectations with a 235 miles range, vs the Tesla that only hits 250 miles. But charging time and comfort are in favor of the Tesla’s vehicle.

In conclusion, a long-distance road trip is better planned with a Tesla Model S, as you’ll be making the most of its supercharging abilities and comfy seats. However, if you’re driving only a few hundred miles, the Chevy Bolt is a great alternative that exceeds range expectations, as long as you remember to use DC fast-charging stations!

Tesla Model S

Last August, I posted about the rumors swirling that the Tesla Model S would look the Aston Martin Rapide concept. Then in October, a “rendered speculation” was created that led many to believe the car might look otherwise. But the rendering seemed to deviate from what Tesla spokesmen claimed would be a large four-door hatchback sedan. Also I found it doubtful that the company would build a car with an obvious Asian sportscar influence in the design.

But the Model S peaking out from under the tarp in Tesla’s official teaser photo very much resembles the Aston Martin Rapide.  Right down to the fender side vents.  Obviously, the Model S will look slightly different when it finally unveiled.  But until then, this is probably the best estimate of what the 4-door electric sedan will look like:

Inside the Tesla Roadster Sport

Tesla Roadster Sport
Tesla recently announced its Roadster Sport edition. To be succinct, the Sport powers from 0-60 mph in 3.7 seconds (.2 seconds faster than the base model), has a sweet HEMI muscle car like orange and black paint job, Yokohama performance tires, custom suspension, and blacked out rims.

So how do you get more juice out of an electric motor? You can’t add performance headers and intakes or any fun widgets like turbo and superchargers. So Tesla hand wound the wires that wrap around the stator to create more power. The stator is the stationary part of an electric generator or electric motor. The non-stationary part on an electric motor is the rotor. Here is a picture of a traditional rotor (left) and stator (right):
Stator and Rotor

Electromagnet

The stator is an electromagnet (see left), meaning when an electric current passes through it, the rotor is magnetically attracted to spin in a certain direction.  So if you hand spin the wires into the stator, you can pack more wires in, allowing more electrical current to pulse through each segment.  The more powerful current sequentially magnetizes each segment  and spins the attracted rotor faster.  Also, I’m not an electrical engineer so you can correct me in the comments section.

The Tesla Roadster is powered by a 3-phase, 4-pole electric motor, producing a maximum net power of 248 hp (185kW). The Sport Model, with its higher density, hand wound stator produces a maximum of 288 hp (215 kW). Both motors are designed for rotational speeds of up to 14,000rpm, and the regular motor delivers an efficiency of typically 90%, or 80% at peak power.  Couple this with Tesla’s new Powertrain 1.5, and you have one of the meanest electric machines ever produced.

OnCars.com Incredibly In-Depth Tesla Roadster Video Review

4 Comments

After the unfortunate Top Gear review of the Tesla Roadster, I thought I would provide a more in-depth and encouraging review hosted by Emile Bouret of OnCars.com.  This three part review is very informative and really covers all the bases, as Emile describes the Tesla Roadster’s design, experience, and performance. You can watch the videos in high quality at OnCars.com, but it was a bit hard to navigate, some of the links sent me to a Maxima review instead of the next part. So I embedded them below.

2009 Tesla Roadster Part 1: Design

This goes over the exterior of the Tesla Roadster. While the car is based on a lengthened Lotus chassis, the two cars only share the same windshield.  The car’s large front intake provides an aggressive look, and more than enough air for the cooling system.

2009 Tesla Roadster Part 2: Interior & User Experience

Don’t let the title fool you, this is actually really interesting. Emile sits inside the Tesla Roadster and starts the car, which is a very unique, Playstation like experience. He also notes that if a law is passed to make electric cars louder, it should amplify the jet turbine sound of the regenerative braking. I don’t really understand how a car can be too quiet and thus a safety concern, especially when most modern family sedans are nearly silent from over 10 feet away.

2009 Tesla Roadster Part 3: Performance

What can be said that hasn’t been said already. 0-60 in 3.9 seconds, instant full torque, and zero emissions.

Top Gear Reviews Tesla Roadster and Honda FCX Clarity Hydrogen

12 Comments

I was browsing AutoBlogGreen today and I found out that Top Gear had done a piece on the Tesla Roadster. This was something I had been waiting for for a very long time, because I love the British show and couldn’t wait for their take on the famous electric supercar. Performance wise, the car, fitted with Tesla’s Powertrain 1.5, definitely impressed Jeremy Clarkson, likening the car to broadband motoring in a world of dial-up. However, that was before the car’s battery died after 50 miles of driving. Then they were not impressed by the 16 odd hours it would take them to charge it back up. So they got another Tesla Roadster, which Jeremy managed to overheat (overheated motor, he said, which is odd because the electric motor is just air-cooled for its nominal cooling requirement). To add insult to injury, somehow, the brakes broke on the first one while it was sitting in the garage. So this led the show’s hosts to deem the car impractical for today’s world of driving. Here is the Top Gear: Tesla Roadster Youtube video, which will probably go down soon:

[EDIT: If you want to see Tesla’s side of the story, scroll down to the first comment of this article, by Rachel Konrad, Senior Communications Manager of Tesla Motors. Top Gear’s piece ended up being somewhat of a PR disaster regarding Tesla’s reliability, and hearing another side to the story is helpful.  I won’t make a judgment on what happened because I wasn’t there and I can only write about what was in the video.]

The other host on the show, James May, sparked my curiosity at the end, talking about finding an alternative to the battery electric car and future of motoring. So I found the James’ segment on the Honda FCX Clarity Hydrogen electric car. I have never been a fan of hydrogen cars, because they are about as technologically advanced as spaceships and don’t seem like they will be practical economically. Some say the car, right now, would be priced at $10,000,000. Plus, hydrogen is something Shell can sell you, so of course they will push this on us. But I was impressed by the FCX Clarity Hydrogen, which is really basically just an electric car with a hydrogen powered generator that will extend the range to around 300 miles. So it utilizes the superior efficiency of an electric motor while eliminating the bulk and range limits of batteries.  Also according to the video, hydrogen is about at cheap as gas and the car’s only byproduct is water. Don’t be fooled though, the hydrogen car is very far down the road. Here is the Top Gear: Honda FCX Clarity Hydrogen segment:
