40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Porsche 918 Spyder configurator goes live

That didn't take long. The debut model of the new Porsche 918 Spyder is still thronged by onlookers at the Frankfurt Motor Show, while the German sports car maker is hard at work putting the first version of the supercar's configuration page online. Considering Porsche configurators are some of our favorite time-wasters of the genre, we expect car-guy productivity to drop by a few percentage points over the rest of the day.
So, the 918 dream-maker doesn't list and prices as yet, and that's too bad. But considering the car is due to start off at $845,000 in the US, chances are good that unless you're reading this from the shallow end of your Uncle Scrooge-spec money pool, the cost of any part of the 918 is academic to you anyway.
To start, Porsche is offering twelve paint colors, three wheel choices and seven two-tone interior treatments. Standard lightweight bucket seats and a set of chairs with "firmer padding" are on offer, too. The options list is mostly populated with interior bits, though many - an anti-reflection interior, fire extinguisher, six-point seatbelts - are racing-oriented or functional. Note that Porsche is also kind enough to offer just one cupholder as an optional extra; the unit is made of aluminum and is detachable so that you won't have to carry the extra weight during racing. Also, Porsche probably puts you on some kind of naughty 'list' if you order one...

Porsche LMP1 to use 4-cyl hybrid powertrain [w/poll]

With the Formula One season - and indeed his entire F1 career - now behind him, Mark Webber took advantage of his early release from Red Bull Racing to try out the new LMP1 which Porsche is developing, undertaking the final test session of 2013 before Porsche throws it head first into the FIA World Endurance Championship next April. The session - which followed previous tests at Magny-Cours, Monza, Paul Ricard and the Eurospeedway at Lausitz - was held at the Algarve circuit in Portimão, Portgual, in collaboration with Michelin, which is developing the tires for the car. But that's hardly the news here.
No, the news is the first confirmation we've seen on the type of powertrain Porsche has developed for its new Le Mans prototype: a gasoline-burning four-cylinder engine with direct injection and two energy recovery systems. This contrasts sharply with the V6 turbodiesel and single electric motor used by Audi in the R18 e-tron Quattro (or at least the outgoing version) or the naturally-aspirated V8 and single electric motor found in the Toyota TS030. Flexibility in the rules set down by the FIA and ACO give the manufacturers that kind of latitude, prompting F1 teams like Ferrari and Renault to consider developing their new engines for Le Mans prototypes as well.
At this point Porsche isn't saying how large its four-cylinder engine is or how much power it will produce. But it'll be interesting, to say the least, to see how it fares against the Audi and Toyota in next year's championship and at Le Mans when it'll be piloted by Webber, former Lola LMP1 driver Neel Jani and Audi's own 2011 Le Mans-winning pair of Romain Dumas and Timo Bernhard.
