Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.

1989 Porsche 911 Turbo rolls out of Harry's Garage

It's getting increasing hard not to feel a little envious of Harry Metcalfe's collection of vehicles, especially with his latest purchase. He now owns the trinity of '80s European supercars with an '87 Lamborghini Countach, an '87 Ferrari Testarossa, and the recent addition of an '89 Porsche 911 Turbo. With the other two already featured in videos, the example from Stuttgart gets the focus in Metcalfe's latest clip. These turbos have a reputation for being a bit of a handful to drive, and according to Metcalfe that notoriety isn't entirely undeserved. With no power steering, floor-mounted pedals, oddly placed controls and lots of turbo lag, this era of 911 Turbo is difficult to master. However, it's a wonderful challenge that really engages the driver, according to Metcalfe. While a very different vehicle from the Countach or Testarossa, it's clear that this 911 Turbo is still a beloved member in Metcalfe's trio of '80s supercars. Let him give you a detailed explanation why in this video.

Chris Harris gets filthy in a WRC-ready Porsche 911 RGT

Last time we rode with Chris Harris we were shotgun in the tan leather seat of his used-yet-immaculate Ferrari FF. This time we're strapped into a black racing bucket of a filthy Porsche 911 rally car, one that led Harris to effuse, "I don't think I've driven a more exciting car this year, hypercars included." The thrills come courtesy of a 997-series Cup Car that's been reworked by Tuthill Porsche to run in the RGT-class rally series that will piggyback on five World Rally Championship and European Rally Championship races this year. It's not quite the Rothmans Dakar monster, but the RGT series gives privateers an affordable way into rallying with cars that look different and are different from one another. This one kept its 3.8-liter, 444-horsepower 997 Cup engine, but the 39-milllimeter restrictor drops that to about 350 hp. Beyond that are a new rollcage, gear ratios, suspension, fuel tank, underfloor protection and just about everything else. Said the man who built it, it cost "a lot, and it's still costing." But Harris says even though you "have to have your wits about you," it's a hoot to drive. And this is one of the few times you'll hear the phrase "What a tool!" used as a compliment.
