A beastly 1979 Porsche 930 is unleashed by Petrolicious

The 911 Turbo held a special place in Porsche's lineup for decades. Much of the mystique came from its performance potential, but that huge capability also required a deft hand and foot to keep things in check. These days even the most basic 911 packs turbos, but Grant Karnes and his 1979 Porsche 930 demonstrate why the early models remain classics in the latest video from Petrolicious. Karnes says he gets attention from everyone he passes in his 930, and it's easy to understand why. Even before the coupe comes into view, the upgraded, turbocharged engine pops and crackles with a wonderfully raw sound. People then see the Porsche's classic combination of wide fenders and a big rear spoiler. Karnes also adds a vintage racing vibe with Martini decals on the hood and doors, and his license plate tells folks exactly what kind of machine this is. Plus, if you happen to spot this car at night, the exhaust can shoot bursts of flames. Porsches are a fairly common subject in Petrolicious' videos, and they run the gamut from well-worn classics to heavily modded canyon carvers. Karnes' 930 leans more in the latter direction but still maintains a vintage look. He promises the coupe is always exciting to drive, and this clip does a fantastic job of showing why.

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).

Alonso wants an NSX, but did Honda block him from Le Mans?

One of the biggest changes in store for the 2015 Formula One World Championship will see Fernando Alonso moving back to McLaren. That means he'll be driving under Honda power for the first time, after spending the bulk of his career driving for Renault and Ferrari. And being Honda's new poster child, as the two-time World Champion is fast discovering, has its advantages and its drawbacks. According to the latest reports, Alonso had been negotiating a clause in his contract with McLaren that could have seen him driving a Porsche 919 Hybrid at Le Mans this year, but Honda reportedly stepped in at the last minute and scuttled the plan. The drive would have been Alonso's first in the famous 24-hour race, after having had the honor of waving the flag at La Sarthe last summer. In one of the wilder rumors that emerged during the prolonged silence over his move for this season, the Spaniard was also linked to a potential return for Ferrari to Le Mans. That prospect came to naught, and now the Porsche deal has been wheeled into the garage, as well. The upcoming F1 season is expected to be one of transition, adjustment and development for McLaren and Honda, but the Japanese automaker's involvement in his hiring may not be all bad news for Alonso. Following the reveal of the new Acura NSX, Alonso tweeted "You still don't know, but one day we will be together..." followed by a series of heart-eyed smiley-face emoticons and accompanies by images of Honda's new supercar. The implication is that the two-time World Champion is expecting to get his talented hands on an NSX of his own, and we can certainly see how Honda would appreciate the imagery of Fernando driving around in its flagship. Even if it doesn't, though, we're sure McLaren would be glad to hook him up with a company car of its own – though Lewis Hamilton encountered some trouble securing (a very specific) one for himself. Even discounting the front-running F1 machinery he's been tasked with piloting on track to an impressive 32 career wins, Alonso has had some lustworthy company cars at his disposal over the years. At Renault, he had a Megane RS to drive, and during his last stint at McLaren, he had an SLR 722. But since signing with Ferrari, he's been given the keys to FCA models as varied as a Ferrari FF, a special 599 GTO, a Maserati GranCabrio, a Jeep Grand Cherokee SRT and an Abarth 695... and those are just the ones we know about.
