2015 Lexus GS F is camo-free and frisky

Other than some missing badges and (hopefully) a not-yet-finished rear fascia, what you see here is an undisguised look at the long-awaited Lexus GS F high-performance sedan. Lexus' answer to the BMW M5 and Mercedes-Benz E63 AMG, the GS F has been spotted again.
Unlike our previous spy shots, though, this time around, the sporty Lexus has been caught testing on the Nürburgring, so our spy shooters have managed to get a look at the car from all angles. Building on the aggressive styling of the GS F-Sport, the GS F gets bigger air intakes and a lower chin spoiler up front. Like before, we see the signature stacked exhaust outlets, but they still seemed roughed into rear fascia, which gets an aero-aiding diffuser.
We still only have guesses as to what will be under the hood, but a 465-horsepower, 5.0-liter V8 sounds good to us. Expect to see the production GS F on the road by 2015.

Lexus LF-NX gets turbocharged second act [w/video]

Don't let its supremely polarizing appearance fool you, this is not the Lexus LF-NX Concept that you (probably) had a strong reaction to when it debuted at the Frankfurt Motor Show. The German version of the concept car featured a variant of the Lexus Hybrid Drive system, while this LF-NX Turbo, well, it has "turbo" in the name, you see?
If fact, the namesake turbo would appear to be the first for Lexus; getting off the line in the forced-induction race with a 2.0T four-cylinder engine that "paves the way for the introduction of turbocharged powerplants in future Lexus models." Sounds good to us. The new turbo four has plenty of tricky tech, too. Lexus tells us that the engine makes use of an advanced high tumble port, fan spray fuel injection, VVT-iw variable valve timing, an exhaust manifold integrated into the cylinder head and, of course, a twin-scroll turbo with active wastegate valve. The result is said to be a blown engine that offers quick throttle response and "exhilarating" performance, along with excellent fuel economy and low tailpipe emissions.
As for the rest of the LF-NX Turbo concept? Well, you've seen this angular concept crossover before, basically. There's a slightly tweaked front end and new wheels sitting in slightly cleaned-up wheel wells. The boldest-yet version of the spindle grille still bears an uncanny resemblance to The Predator, and the slightly revised exterior visuals won't change your made-up-mind about this vision of Lexus' future.

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.
