2016 Italian Grand Prix race recap

The Italian Grand Prix at Monza is called the Temple of Power. Furthermore, the winning driver in Italy started on pole in 13 of the last 16 years, and only one driver in that time has won the Italian GP from behind the front row of the grid: Rubens Barrichello in 2002 and 2009. By this point in the current Formula 1 season (era?) we know what it means when a track emphasizes both power and pole position: Mercedes-AMG Petronas. The Silver Arrows locked out the front row with Lewis Hamilton on pole. A poor start prevented the Briton from capitalizing on the advantage, so teammate Nico Rosberg and four other drivers swept by him before the end of the second turn. Mercedes would later say a clutch issue caused Hamilton's botched start, but that didn't help the man who'd just fallen to sixth place. Rosberg got about two laps of television coverage on his way to an unbothered victory ahead of Hamilton. Ferrari made Hamilton's second-place finish easier by sticking to a two-stop strategy; both Mercedes drivers pitted once. We aren't sure why Ferrari didn't at least attempt a one-stopper once Sebastian Vettel and Kimi Raikkonen had been gifted second and third on track. A pit stop took about 23 seconds from entry to exit and Vettel finished third, six seconds behind Hamilton. Raikkonen finished fourth, another seven seconds behind Vettel. Perhaps the Scuderia's tire usage wouldn't allow longer stints, but we'll never know. Daniel Ricciardo wielded his Red Bull like a scalpel to make an impeccable pass on Valtteri Bottas in the Williams and take fifth place. Ricciardo, trailing another Italian province behind, somehow closed the gap on Bottas in just the braking zone of Turn 1, pulling alongside near the apex without locking a wheel on entry nor running wide on exit. Bottas claimed sixth ahead of Red Bull's Max Verstappen, Sergio Perez in the Force India, Felipe Massa in the second Williams, and Nico Hulkenberg in the second Force India sealing the top ten. Monza did spring a few on-track surprises. Esteban Gutierrez drove Haas F1 into Q3 for the first time this season, the Mexican setting the sixth-best time in Q2. Manor Racing planned for Monza all season, Pascal Wehrlein repaying the effort by qualifying 13th. Fernando Alonso pitted his McLaren on Lap 50 of the 53-lap race for a set of super soft Pirellis, then set the fastest lap. It's Honda's first fastest lap since 1992. The biggest moments happened off the track.

Mercedes-Benz engines with 48-volt systems coming in 2017

As part of a big green push announced yesterday, Mercedes-Benz is jumping into the world of 48-volt power. The company will launch a new family of efficient gasoline engines next year and will begin rolling out 48-volt systems with it, likely in its more expensive cars first. Mercedes will use the 48-volt systems to power mild-hybrid functions like energy recuperation (commonly called brake regeneration), engine stop-start, electric boost, and even moving a car from a stop on electric power alone. These features will be enabled through either an integrated starter-generator (Mercedes abbreviates it ISG) or a belt-driven generator (RSG). (RSG is from the German word for belt-driven generator, Riemenstartergeneratoren. That's your language lesson for the day.) Mercedes didn't offer many other details on the new family of engines. There are 48-volt systems already in production; Audi's three-compressor SQ7 engine uses an electric supercharger run by a 48-volt system, and there's a new SQ5 diesel on the horizon that will use a similar setup with the medium-voltage system. Electric superchargers require a lot of juice, which can be fed by either a supercapacitor or batteries in a 48-volt system. Why 48-volt Matters: Current hybrid and battery-electric vehicles make use of very high voltages in their batteries, motors, and the wiring that connects them, usually around 200 to 600 volts. The high voltage gives them enough power to move a big vehicle, but it also creates safety issues. The way to mitigate those safety issues is with added equipment, and that increases both cost and weight. You can see where this is going. By switching to a 48-volt system, the high-voltage issues go away and the electrical architecture benefits from four times the voltage of a normal vehicle system and uses the same current, providing four times the power. The electrical architecture will cost more than a 12-volt system but less than the complex and more dangerous systems in current electrified vehicles. The added cost makes sense now because automakers are running out of ways to wisely spend money for efficiency gains. Cars can retain a cheaper 12-volt battery for lower-power accessories and run the high-draw systems on the 48-volt circuit. The industry is moving toward 48-volt power, with the SAE working on a standard for the systems and Delphi claiming a 10-percent increase in fuel economy for cars that make the switch.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
