Cost to drop 691 horsepower in your Tesla Model S P85D? $14,600

Not mentioned during the much-hyped announcement event last night for the Tesla Model S Dual Motor "D" and Autopilot "A" options were how much those advancements will cost. Today, Tesla updated the Model S order page and those pesky little numbers are now available. As it turns out, opting for all of the features mentioned last night will add over $18,000 to the price of your $93,400 Model S P85. To get all of the benefits mentioned last night will add over $18,000 to the price of your Model S. Let's start by revealing the D's price. To add the second-motor to either the 60- or the 85-kWh Model S costs $4,000. That drops the 0-60 time by 0.2 seconds and ups the top speed by five miles per hour in the 60 (to 125 mph) and 30 mph in the 85 (to 155 mph). Interestingly, the overall horsepower output (according to Tesla) is 4 hp lower (376 compared to 380), but the car apparently gets the speed benefits by putting 188 hp on each axle. On the P85D, everything's different. Here, Tesla isn't just dividing the motor into two smaller versions. Instead, the old 470-hp motor is replaced by a "High Performance Dual Motor" setup that has a total output of 691 hp, 221 hp in the front and 470 hp in back. That's how you get the headline 3.2-second 0-60 time alongside the same 155 mph top speed, but the price tag jumps to $14,600 for the setup. Tesla CEO Elon Musk said last night that the tremendous drop in 0-60 time gets you 10 miles of extra range from the dual-motor setup. But if you don't need the quickness, you can go even further. Without the dual motors, an 85-kWh battery Model S can go 265 miles (EPA numbers). The standard 85D gets its range increased to 295 miles at 65 mph (according to Tesla's numbers) while the quicker P85D can "only" go 275 miles. Dual-motor Model S versions will begin deliveries in February 2015. The A option, officially called the "Tech Package with Autopilot," costs $4,250. This is the way that you can get your Model S to drive itself (on private property) and act as an active safety net to your own driving on public roads. Since all Model S EVs now come standard with a new forward-looking camera, radar and 360-degree ultrasonic sensors, the "Autopilot" part of the package would appear to be mostly a software switch. The rest of the package is rounded out by things like seven years of free navigation map updates, LED running lights, memory seats and more.

Regulators consider adding more carmakers to Takata recall

Volkswagen's diesel emissions scandal has been getting a lot of press recently, but the Takata airbag inflator affair could be grabbing headlines again soon. According to Bloomberg, the National Highway Traffic Safety Administration is contemplating an expansion to the campaign that could add seven automakers to the 12 already affected. They are Jaguar Land Rover, Mercedes-Benz, Spartan Motors, Suzuki, Tesla, Volvo Trucks, and VW Group. To be clear, there's no recall for any of these automakers, yet. The government is simply asking for a full list of vehicles that each of them have with Takata-supplied inflators containing ammonium nitrate propellant. The agency is concerned this substance could play a roll in the ruptures. "NHTSA is considering not only whether to issue an administrative order that would coordinate the remedy programs associated with the current Takata recalls, but also whether such an order should include expansion of the current recalls," the letters say. All seven can be viewed, here. From a report supplied by Takata, the government already knows that the company supplied 887,055 inflators with ammonium-nitrate propellant to VW and 184,926 of them to Tesla. In an incident during the summer, a side airbag allegedly burst in a 2015 VW Tiguan. In early September, NHTSA put out a revised report that there were 23.4 million inflators to be replaced in 19.2 million vehicles in the US. An earlier accounting from the agency had about 34 million of the parts in 30 million cars. High humidity is still believed to be among the biggest risk factors for the ruptures. Although, if ammonium nitrate also gets the blame, some already recalled models might need to be repaired again. Related Video:

Elon Musk's Hyperloop idea still in motion

After teasing the concept in 2012, Tesla CEO Elon Musk released some thoughts on a high-speed transportation project called the Hyperloop in 2013. He then promptly renounced any claim on the idea and said he would not actually build the open source project. The hyperloop didn't die, though, and is still attracting new brainpower. Hyperloop Transportation Technologies was officially formed with a JumpStartFund late last year, a few months after Musk made the concept public. The company has since grown into a collective of about 100 engineers who have full-time gigs with companies such as Boeing, Airbus, NASA and, of course, Musk's own SpaceX, Wired says. Some students at UCLA are taking part in the design process, which is detailed in a new "crowdstorm" document. The idea behind the Hyperloop is to build above-ground tubes where passenger capsules devoid of friction (with the help of either air compression or magnetic levitation) can travel up to 800 miles per hour between cities such as Los Angeles and San Francisco. The HTT collective is already talking about having economy- and business-class capsules. The good news is that the group says the early predictions for Hyperloop remain realistic. That means a timeframe of about a decade to complete the first system with a price tag of between $6 billion and $10 billion is still on the table. For now, at least. Hyperloop Transportation Technologies, Inc. Announces New Designs, Crowdstorming Document and Core Team EL SEGUNDO, Calif., Dec. 19, 2014 /PRNewswire/ -- Hyperloop Transportation Technologies, Inc. powered by JumpStartFund announced today the crossing of major milestones, bringing the company closer to the goal of creating a working high speed mass transit system. These milestones include the finalization of the company's 100 core team members and the publishing of a new crowdstorm document. Recently acquiring its 100 core team members, Hyperloop Transportation Technologies is powered by the unique collaboration platform JumpStartFund. These 100 members are professionals, engineers and designers from some of the most esteemed organizations on the planet, including Boeing, Airbus, NASA, Harvard, UCLA, Stanford, and others, collaborating globally in the U.S., Asia, Australia and Europe. The company released a new crowdstorm document expanding on concepts and sharing the most recent developments produced by the company. Highlights from the paper include a detailed cost, route and safety analyses.
