Why won't automakers slap on a turbo badge anymore?

Where have all the turbos gone? Not the actual pieces that go in the engine, mind you, those are everywhere these days as automakers downsize cylinder counts and boost efficiency and CO2 claims. But the turbo badges and fanfare are missing. Back when turbos were something to get excited about there was "turbo-driven," "turbonium," and "The Turbo Zone," among other silly lines. But now that basically every car is getting some sort of boost even on the lowliest trims, automakers are almost sliding in the turbos under the radar. Or if you look at some of the nomenclature, pretending they don't exist at all. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border. The latest automaker to hide that it has boosted the turbo presence is Porsche with the 2017 911 lineup. Even the standard Carrera models now get turbocharged flat-six engines, meaning the 911 Turbo models aren't quite as special as they once were. Porsche is in a sticky situation with this. The 911 Turbo, after all, signifies where the 911 family takes off from being a sports car and becomes the Ferrari fighter. The 911 Turbo badge shows where the car goes from being sane to lunatic. It's an important border, but now Porsche has crossed it and is trying to downplay the fact. There are a lot of exaggerations with displacement badges today, with claims the 2.0-liter turbo four in a Mercedes C Class equates to a naturally aspirated 3.0-liter six to make a C300. Volvo is pretty far up there, too, saying an XC90 T8 means V8 power, even though it's a 2.0-liter turbocharged and supercharged four with electric assist. I don't know why BMW can't just call the car a 330i Turbo, rather than inflating the numbers up to 340i. Saab tried all of this back in the '90s when it decided to turbocharge its entire lineup, from light pressure units all the way up to models actually called "Saab 9-3 HOT" (for high-output turbo). But then the brand deleted any external reference to the turbo under the hood and people wondered why they were buying a $42,000 four-cylinder convertible. And that didn't turn out well. Even though these turbo replacements often make more power than their naturally aspirated predecessors, they're very different engines. People knew something changed when they exchanged their leased 328i with a 3.0-liter six for a 328i with a 2.0-liter turbo four.

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.

Recharge Wrap-up: BMW cars to share i tech, Jordan to build solar EV charging network

Jordan is looking to promote EVs and build a solar charging network. The country is waiving import tariffs on electric cars, and is spending $120 million on solar chargers. It plans to build 3,000 charging stations, along with 30 MW of solar power. Some chargers will be powered by solar canopies, while others will get electricity from nearby solar farms. Jordan's solar plan should also help to lessen the amount of energy it needs to import from nearby countries. Read more from Navigant Research, or at Green Car Reports. BMW's mainstream cars will benefit from technology borrowed from the i3 and i8, according to BMW sales head Ian Robertson. In an interview with Automotive News, Robertson said that next-generation cars will use carbon fiber more extensively, and that more cars will get plug-in technology. He said that about half of i3 buyers opt for the range extender and added that it is incorrect to refer to a range-extended electric vehicle as a plug-in hybrid. Read more at Automotive News. The ethanol market should remain healthy despite falling oil prices. While cheap oil could drive down ethanol prices, demand still remains due to the federal biofuels standard. Additionally, ethanol producers may find it cheaper to ship their products as domestic oil production drops and railroad shipping opens up. Ethanol byproducts like distillers grains continue to sell, and foreign demand continues as other countries impose their own renewable fuel standards. Read more at Yahoo News. Via Motors will launch the production of an electric Chevrolet Silverado. The company will convert the pickups into range-extended EVs at its assembly line in Mexico, near GM's Silverado plant. Via has the capacity to produce 10,000 vehicles per year at its Mexico facility. Via Motors Chairman (and former GM Vice Chairman during the early days of the Chevrolet Volt project) Bob Lutz wants to help make EVs mainstream in America, and believes that requires electrifying pickups and SUVs. Read more in the press release below.
