2015 Brazilian Grand Prix is the same as it ever was

At this point, we hope Nico Rosberg is planning to carry his current qualifying form into the 2016 season and back it up with the same kind of race-day cojones he showed winning the race in Mexico City two weeks ago. The Mercedes-AMG Petronas driver got it right enough again on Saturday afternoon to take his fifth consecutive pole position ahead of teammate Lewis Hamilton by almost a tenth of a second. It's the same one-two from Brazil last year. The bad news for the rest of the field is that the winner in Brazil the last seven years has been one of the two drivers on the front row. Last year it was the Williams duo that lined up behind Mercedes, this year it's Ferrari. Sebastian Vettel plays the stalking horse, securing third in his Ferrari ahead of teammate Kimi Raikkonen in fourth. Williams driver Valtteri Bottas actually qualified in fourth, but he had to serve a three-spot grid penalty for passing under red flags in Free Practice 2, so he started sixth. That promoted Sahara Force India driver Nico Hulkenberg up to fifth. Daniil Kvyat was the quickest representative from Infiniti Red Bull Racing, getting into seventh even with a Renault power unit that's weak on some of the key stretches at the Interlagos track. Felipe Massa had the second Williams in eighth, in front of the second Red Bull driven by Daniel Ricciardo in ninth. Toro Rosso hasn't confirmed its drivers for next year but Max Verstappen keeps making it hard to look elsewhere, taking 10th. Rosberg is working nearly the same trick he pulled last year: drive like a second driver for most of the year, drive like a world champion for the last quarter of a season. He pulled away at the start and covered Hamilton just enough on the run to the first corner to keep Hamilton on the outside. By the end of Turn 1 the German had the lead and didn't give it up for the rest of the race outside of pit stops. Without overwhelming pace to pass and unable to follow closely, Hamilton could do nothing except ask his team for a different strategy to go for the win. When Mercedes told him "No," trying to protect Rosberg's second place in the championship ahead of Vettel, that was the race. Just like last year, Rosberg and Hamilton finished one-two. Vettel, Raikkonen, Bottas, Hulkenberg, and Kvyat drove lonely races to finish in positions three through seven.

Hyundai, Genesis, Subaru warn their dealers about markups

Six weeks ago, word got out that Ford's VP of sales for the U.S. and Canada wrote one of those "It has come to our attention..." e-mails to the automaker's dealer body. The VP's problem was dealers trying to get reservation deposits for the Ford F-150 Lightning well above the official $100 fee. The tomfoolery resulted in interactions "with customers in a manner that is negatively impacting customer satisfaction and damaging to the Ford Motor Company brand and Dealer Body reputation." Two weeks later, GM told its dealers to cut out the reservation gaming and the markups on the 2023 Chevrolet Corvette Z06, banditry that's been going on for two years. Two weeks ago, Ford was back at it, this time about markups on the Bronco. Last week, Asian automakers swept into the melee, with Hyundai and Genesis, Subaru, and Infiniti writing letters to their dealers to deliver some variant of, "Stop pissing off the customers." Automotive News reported an SVP at Hyundai Motor America and the COO at Genesis Motor North America sent letters to their dealers expressing disappointment at "certain pricing practices which, if left unchecked, will have a negative impact on the health of our brand." One of the practices mentioned was dealer markups, another was the bait-and-switch, with dealers advertising one price then charging a higher price once the customer showed up at the lot. The letters acknowledged that dealers are separate companies to the automakers and have the right to set their own prices. The automakers cannot interfere with that; their leverage is distributing allocations and perks such as advertising support and financial incentives. So, like a movie boss letting the protagonist go on a technicality, the brands wrote, "we cannot stand idly by watching the actions of the aforementioned dealers undo all the efforts we collectively have put into making these brands what they are today." Jalopnik got tipped to a letter Subaru of America CEO Thomas Doll sent to that brand's dealers. Doll's polite yet insistent tone was the result of a letter a loyal Subaru owner sent to the automaker's VP of Customer Advocacy. In the market for a third brand-new Forester, the owner said they encountered a "tax" labeled a "Low Inventory Surcharge" of as much as $6,000, putting the Forester out of reach.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.
