Weekly Recap: The cost of Tesla's ambitious plans for growth

Tesla has ambitious plans for growth, and they won't come cheap. The electric-car maker said this week it plans to spend $1.5 billion in 2015 to expand production capacity, launch the Model X crossover and continue work on its Gigafactory, which is being built outside of Reno, NV. The company is also investing in its stores, service centers and charging network, which is expected to grow by more than 50 percent this year. Plus, it's still working on the Model 3, which is scheduled to arrive in 2017. "We're going to spend staggering amounts of money on [capital expenditures]," Tesla chairman and CEO Elon Musk said on an investor call. He then added: "For a good reason. And with a great ROI [return on investment]." They're bold plans, and Musk is clearly willing to put Tesla's money where his mouth is. That's why the company is projecting a whopping 70-percent increase in deliveries this year, for a total of 55,000 cars. A large chunk of that growth will come from the addition of the Model X crossover to Tesla's portfolio, and the company already has nearly 20,000 reservations for it. More than 30 Model X prototypes have been built, and it is expected to begin shipping to customers this summer. Musk said he's "highly confident" the vehicle, which has experienced delays, will arrive on time. The company also had more than 10,000 orders for the Model S at the start of the year. The big spending plans caused a stir, even though Tesla spent $369 million on capital expenditures in the fourth quarter alone. In a note to investors, Morgan Stanley analysts called the costs required to keep pace with Tesla's demand "eye-wateringly high," and said the $1.5-billion figure was nearly double their expectations. Still, Musk is not thinking small and suggested that his company could be as big in 10 years as Apple is now if Tesla's growth continues. His optimism comes as the company actually reported a $294-million net loss in 2014, more than its $74-million loss in 2013. The money, however, continues to roll in, and total revenues increased to $3.2 billion in 2014, up from $2 billion in 2013 and a dramatic surge from $413 million in 2012. More of the same is expected this year, and the company could reach $6 billion in revenue. As Morgan Stanley noted, it "seems Tesla is preparing to be a much larger company than we have forecasted." It's certainly spending that way.

Recharge Wrap-up: liquid-cooled Tesla Supercharger, Acenta+ Leaf

A new video offers a close look at Tesla's updated Supercharger. Recently, Elon Musk spoke about the new charging station with a thinner, suppler liquid-cooled cable that is not only easier to manage, but has the potential to handle larger loads and offer quicker recharging. The first examples have been installed in Mountain View, CA, which we can see in this video. Besides the new cable, the new Supercharger also features a solid "button" on the charging handle as well as vents around the bottom of the unit. The video even shows thermal imaging of the new Supercharger, which shows the cable to be cooler than the cameraman usually records. See for yourself in the video above, and read more at Treehugger. Nissan has added a new trim level to the Leaf in the UK. The Acenta+ slots above the Acenta and just below the range-topping Tekna. It comes standard with the 6.6-kW onboard charger and Mode-3 32-amp (EVSE) cable. Using a fast charger, the Acenta+ Leaf can charge to 100 percent in just four hours. "We're delighted to add a new member to the Leaf family in the UK," says Nissan Motor GB Managing Director James Wright. "More than 9,500 Leafs have already been sold here and Nissan is the undisputed leader in the EV market. This new model delivers exceptional value and showcases the Leaf's incredible technology and engineering." Read more at Next Green Car. Mercedes-Benz Malaysia says its vehicles are compatible with B10 biodiesel blend. Malaysia recently announced a mandate for diesel to be sold blended with 10 percent palm-oil based biodiesel, after which, carmakers like BMW and Mercedes-Benz came forward with concerns over compatibility with their vehicles. "We have evaluated carefully the influence of B10 Biodiesel blends on our current diesel vehicles for the Malaysian market and we are now able to confirm its compatibility," says Mercedes-Benz Malaysia President and CEO Roland Folger. "We have service intervals of 12,000 km to ensure that our customers are not affected by the diesel quality. Our diesel-powered vehicles currently sold in Malaysia were seen to have run both smoothly and safely with the use of the B10 biodiesel blend." Read more from Paul Tan's Automotive News.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
