Veneno Roadster, One:1, One-77, LaFerrari, P1, Veyron headline 25-car Bonham's auction

Bonhams is holding a no-reserve auction in fall 2019 that includes some of the most valuable and sought-after supercars of the past decade. The lot of 25 beautiful collector items includes a Lamborghini Veneno Roadster, a Koenigsegg One:1, an Aston Martin One-77, a Ferrari LaFerrari, a McLaren P1, and a Bugatti Veyron. The collection, which was seized from a corrupt politician from Equatorial Guinea, is valued at roughly $13 million. If selling off future classics that are still in their infancy as collector items seems strange, it's because this is not a straightforward situation. These cars will be sold off by the State of Geneva, not a person. The collection was previously owned by the vice president of Equatorial Guinea, Teodoro Obiang, but the cars were seized when he was placed under investigation for money laundering and unfair management of public interests. These 25 cars, which were located in Geneva, were first sequestered in fall 2016. A trial court ordered them sold off, and the money earned from the sales would be invested in social programs that benefit Equatorial Guinea. And so, Equatorial Guinea is about to see an influx of cash, as every vehicle is valued in the hundreds of thousands, if not millions, of dollars. The rarest might be the Koenigsegg One:1. One of only six remaining, it has 371 miles on the dial, and is valued at roughly $1.8 million. The Lamborghini Veneno Roadster, one of nine in the world, is a close second. It has 202 miles logged, and is valued at about $5.1 million. The Aston Martin One-77 is another rare bird. It is example No. 35 of 77, holds a 7.3-liter V12 engine, and is valued at about $1.4 million. A McLaren P1, Ferrari LaFerrari, and Bugatti Veyron 16.4 round out the top of the list. The remaining cars are not fully detailed, but they include examples from Mercedes-Maybach, Bentley, Maserati and Porsche. The auction will take place on Sunday, Sept. 29, at the Bonmont Golf & Country Club near Lake Geneva. For more photos and information, visit Bonhams.

Porsche 911 GT2 test mule caught in the snow

This may look like a weird, cobbled-together Porsche, but insiders tell us we're actually looking at the forthcoming GT2. Maybe even a GT2 RS. Those schooled in the intricacies of Zuffenhausen nomenclature will be suitably excited by now. But for the rest of us, the GT2 (with or without the RS) represents the pinnacle of the most hardcore 911s. It's essentially a 911 Turbo without the all-wheel drive but some other goodies thrown in – or to put it another way, it is to the Turbo what the GT3 is to the 911 Carrera. Porsche first did a 911 GT2 back in 1993 based on the 993-generation model. It then did another based on the 996, and then on the 997. But the last one we saw was the GT2 RS that came out in 2010, packing 612 horsepower channeled exclusively to the rear wheels through a six-speed manual transmission. The German automaker didn't do a GT2 version of the 991, but now that the entire model line is undergoing a transformation – and an near-complete switch to turbo power – it apparently has another one in store for us. Aside from ditching the Turbo's all-wheel drive, the new GT2 will be lighter and pack more power – as much as 700 hp, from what we hear. As you can see from the spy shots, the test mule spotted romping in the snow is also wearing larger exhaust tips and the signature GT2 RS black hood. Expect the finished product to wear its own shoes and a more extreme aero kit as well. The question on everyone's minds will be whether it will, like the latest GT3 and GT3 RS, be offered only with a dual-clutch transmission, a conventional manual, or the buyer's choice of either. We'll find out sooner or later as the most extreme of Elfens is tipped to surface late next year. Related Video:

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
