McLaren Speedtail revealed — it's a silver speeding bullet

The McLaren Speedtail hypercar is finally here, and it's a streamlined stunner. The whole car is slicker than a bar of soap, and everything about it is there to make it the fastest McLaren road car in history — a combination of sophisticated design and astonishing speed. Grilles and air intakes are kept small and out of the way. It has a long tapering tail. The front wheels have large, smooth carbon-fiber aero-covers that remain fixed as the wheels rotate, to smooth out turbulence from the wheels. Ducts and air passages are all designed to further reduce turbulence, and of course that's the point of the long tail. Air flow for the engine comes from a snorkel intake that is so minimal you can't even see it in profile. Some of the particularly curious parts are the patented rear active spoilers. The flaps appear to not have any kind of joint or gap where they lift. The cockpit is suitably futuristic and unique, too. As the company had previously mentioned, the seat is in the center, as with the old McLaren F1 road car. Immediately in front of the driver is the steering wheel and a main screen for instruments, and to either side are additional screens for other information and interfaces. At the base of either pillar are two smaller screens which are connected to cameras that substitute side mirrors for less drag — and for even less drag, the cameras can be retracted. In what seems like a nod to airplanes, key controls, knobs and switches are above the driver on the ceiling — even the gear select buttons are up there. McLaren revealed its ultimate Ultimate Series car on Friday, offering details only hinted at before. The car almost looks more like a land-speed-record car than a road car. The automaker says the Speedtail is its most aerodynamic creation ever, and that this was its "singleminded vision" — not hard to believe, looking at it: "A jaw-dropping elongated body makes it as much a work of art as a masterpiece of technology." Seen from above, the overall car and its passenger compartment are shaped like a teardrop, which McLaren calls the fastest shape in nature. And indeed this is McLaren's fastest car. Its hybrid powertrain puts out over 1,000 horsepower. (McLaren rates it as 1,035 bhp, so horsepower is just under 1,050.) We applaud the press-release writer's use of the word relentless here: "The hybrid powertrain enables a relentless increase in vehicle speed. ..." Top speed is 250 mph — exceeding the F1's 243 mph.

McLaren 570S Track Pack removes 55 pounds just to add them back at 150 mph

Though the McLaren 570S is plenty sporty as-is, the British supercar builder decided there was room for improvement. That improvement comes by way of a new Track Pack option for the sports car. The meat of the upgrade are a gaggle of lighter parts to go along with a new rear wing. Inside, leather upholstery is swapped for Alcantara, and the standard buckets are replaced with carbon fiber racing-style units. Combined with lighter wheels, the package reduces the 570S's weight by 55 pounds. The new rear wing, exclusive to the 570S, nullifies the weight gain, and then some, once up to supercar-level speeds. The wing is 12 mm taller than the stock example, and produces an extra 64 pounds of downforce at 150 miles per hour. The other performance-oriented goody included in the package is the McLaren Track Telemetry system. This app records lap times, sector time splits, and logs data for analysis of your performance. Because McLaren knows owners will want people to see that they have the most hardcore 570S available, the company made a couple of visual tweaks, too. The roof is painted in what McLaren calls "Dark Palladium" and the exhaust and wheels are given a "stealth-finish." Based on the photos, this seems to be a fancy way of saying "satin black." The Track Pack is now available for ordering and delivery in 2017. The package isn't cheap at a price of GBP16,500, or $20,595 at current exchange rates. But look at it this way. The extra grams from those dollars in your wallet were slowing you down on the track. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.

Kimi Raikkonen fastest in first Belgian Grand Prix practice

SPA-FRANCORCHAMPS, Belgium — Ferrari's Kimi Raikkonen lapped fastest in first practice for the Belgian Grand Prix on Friday but Mercedes, and title contender Lewis Hamilton, still looked every bit the team to beat. A four-time winner at Spa, and with a contract extension for 2018 announced earlier in the week, Raikkonen lapped the longest track on the calendar with a best time of 1 minute 45.502 seconds. The 37-year-old Finn's time was set on the quickest ultra-soft tires, however, while Hamilton — preparing for his 200th race start — was second-fastest and only 0.053 slower on the soft compound. Hamilton was 0.092 faster than Ferrari's world championship leader Sebastian Vettel, with the German third on the timesheets and also setting his time on the quickest but least durable tire. Vettel leads Hamilton by 14 points with nine races remaining. Red Bull's Dutch teenager Max Verstappen, Belgian-born and attracting a huge traveling support of orange-capped fans, was fourth fastest with Australian team mate Daniel Ricciardo fifth. Hamilton's teammate Valtteri Bottas, who bumped into the tire barrier after going off across the gravel and damaged his front wing, was sixth fastest. The session was halted after 15 minutes when Brazilian Felipe Massa, who missed the previous race in Hungary after feeling dizzy in practice, crashed heavily into the tire barrier at turn seven out of Les Combes. He was taken to the medical center for checks, before returning to the pitlane, with his team facing a long job rebuilding the car. The session resumed after a 10 minute stoppage. Williams said the chassis would have to be changed and the team still hoped to get the car back out on track for some of the day's second session, even if that looked like being optimistic. Fernando Alonso suffered a lack of power in his McLaren, but still ended up 13th fastest. Belgian team mate Stoffel Vandoorne, who will start his home race last on Sunday thanks to a 35 place penalty due to a power unit change, was 10th.
