Ryan Tuerck's Ferrari-powered Gumout GT4586 debuts at SEMA

Las Vegas is famous for its shotgun marriages, but the only Sin City nuptials we're interested in is the one officiated by Ryan Tuerck between a Toyota GT86 and the V8 engine from a Ferrari 458 Italia. The insane Gumout GT4586, as it's called, is probably one of the most well-known of the 2016 SEMA Show's stars, after video popped up showing the rear-drive Frankenstein firing up and spitting flames through its weird, front-mounted exhausts. The day after we published that video, which showed the GT86 in mostly bare frame, Gumout and Tuerck posted a second clip showing the Japanese-Italian coupe literally running rings around a 458 while wearing its sheetmetal and yellow-tinted headlights. The car's look in that second video carried over to the Las Vegas Convention Center floor, where the GT4586 showed up sans hood, ludicrously wide tires, and a huge wing and rear diffuser. It's clearly a good-looking car. You can check out our full SEMA gallery above, or, click the video below for a second look at Tuerck's Ferra-yota in action below.

Ferrari reveals LaFerrari-based FXX K in Abu Dhabi

Ever since Ferrari revealed the latest evolution of its flagship hypercar series with the debut of LaFerrari at the Geneva Motor Show last year, the question on everyone's mind – aside from how it would stack up against rivals like the McLaren P1 and Porsche 918 Spyder – is what it would look like in its ultimate, unhinged, track-focused iteration. But now we need wonder no more as the Prancing Horse marque has revealed the new FXX K. The what-letters-now, you ask? FXX K. The name is drawn from the Enzo-based FXX that kicked off the company's client development program the better part of a decade ago, but with an extra letter tacked on to signify the KERS hybrid system on board. In the FXX K, that system has been further optimized: the electric motor now delivers 187 horsepower (instead of 160) and the 6.3-liter V12 has been boosted to 848 hp (up from 789) for a total output of 1,035 prancing ponies – a solid increase from the 950 hp in the road-going LaFerrari, but at 664 pound-feet, it's down in the torque department by 51 lb-ft. Of course output isn't the end of the story, and as you can see the scarlet-clad engineers in Maranello have focused a considerable amount of energy on optimizing the aero package. The front end gets a two-part splitter derived from Ferrari's victorious GT racing program, with vertical fins along the flanks, side skirts extending between the wheels, a dynamic rear wing, vertical fin and a giant diffuser. All of this and more contributes to as much as 50 percent more downforce, aided by increased mechanical grip from the Pirelli racing slicks, with carbon-ceramic brake discs measuring 15 inches across (plus or minus, front to rear) to keep it all in check. Unveiled at Ferrari's Finali Mondiali event at the Yas Marina Circuit in Abu Dhabi, the FXX K also boasts a recalibrated electronic differential, traction control, ABS, Racing SSC (Side Slip Angle Control) and a four-mode Manetinno dial on the center console to switch between levels of electric boost. In short, Ferrari has pulled out all the stops, and we wouldn't be surprised to see the FXX K taking the Fiorano lap record for anything this side of an F1 car. The record is currently held by the 333 SP at 1:11, nine seconds ahead of the road-going LaFerrari's 1:20. That's roughly the same differential between the FXX and the Enzo on which it was based, or the 599XX Evoluzione and the 599 GTO.

Last Ferrari 275 GTS/4 NART Spider could top $26m at auction

One of the prettiest convertible Ferraris built, the NART Spider is also one of the rarest – only ten cars ever left the factory. This specific car was the last off the line, and has the additional distinction of being the only NART Spider sold new in Europe. It was also the only one painted in the Grigio Scuro shade of medium grey from factory. It has been redone in a tasteful red, which is an interesting change from the usual bright Ferrari color. It is also the third-to-last Ferrari 275 to be built altogether. The NART name stands for North American Racing Team, and the drop-top production run is credited to the U.S. Ferrari distributor Luigi Chinetti, who wanted to boost the 275 model's sales with a limited edition convertible model. Originally, Ferrari planned to build 25 cars, but despite the racing pedigree only ten found owners. The first NART Spider finished second in class at the 1967 12 Hours of Sebring, and the model also has some Steve McQueen cool about it due to a starring role in The Thomas Crown Affair. This car, chassis #11057, was sold new in Madrid to a Spanish Foreign Legion colonel, and spent its first 14 years in Spain. In the early 1980s it was bought by a Swiss collector, who had it restored for the first time, and in the mid-90s it moved to the UK. The current paint scheme dates back to 2001, while the interior's beige leather re-trim is from 2009. Despite a gradual change in appearance, it is a fully numbers-matching car that still retains the 300-horsepower Colombo V12 it received at the Maranello factory. A similar NART Spider was auctioned at RM Auctions' Monterey event in 2013, for a staggering $27.5 million. That specific example, finished in a brighter hue was estimated at 17 million tops, so it will be interesting to see whether this darker car will surpass its estimate at the auction held on May 14th.
