Jay Leno takes an in-depth look at a 1964 Porsche 356C restomod

Look nearly anywhere at Dr. Anand Rajani's 1964 Porsche 356C, even the engine, and you would never realize that it boasts around 50 percent more power than stock. There's no sign of any other mods to make the drive a bit more modern, either, but they're there. The car's invisible upgrades result in an amazing transformation of a car that started out pretty great to begin with, and Jay Leno can't seem to get enough of driving this beautiful, gray coupe with restorer John Willhoit. Before going for a drive, Leno takes a deep dive into the details of this Porsche's modifications, particularly of its engine. The result of all the work is a mill that looks visually stock but actually boasts a significant jump in displacement. Willhoit admits this is particular one is a fairly conservative build but output still reaches 145 horsepower and 145 pound-feet of torque. If you're worried that Jay's CNBC show might have a detrimental effect on the quality of the Jay Leno's Garage YouTube video series, then here's your answer. For vintage Porsche fans interested in the nuts and bolts of making them even better, it's hard to imagine Leno making a better clip than this one.

Fastest cars in the world by top speed, 0-60 and quarter mile

A claim for the title of “Fastest Car in the World” might seem easy to settle. ItÂ’s actually anything but: Are we talking production cars, race cars or customized monsters? And what does “fastest” even mean? For years, car publications have tended to define “fastest” in terms of an unbeatable top speed. ThatÂ’s distinct from the “quickest” car in a Usain Bolt-style dash from the starting blocks, as with the familiar 0-60 mph metric. Professionals often focus on track lap times or elapsed time-to-distance, as with a drag racer thatÂ’s first to trip the beam of light at the end of a quarter-mile; or the 1,000-foot trip of nitromethane-powered NHRA Top Fuel and Funny Car dragsters. Something tells us, however, that you're not seeking out an answer of "Brittany Force rewriting the NHRA record books with a 3.659-second pass at a boggling 338.17 mph." For most barroom speed arguments, the focus is firmly on cars you can buy in showrooms, even if many are beyond the financial means of all but the wealthiest buyers and collectors. Here are some of the enduring sources of speed claims, counter-claims, tall tales and taunting dismissals that are the lifeblood of car enthusiasts – now with EVs adding an unexpected twist to these passionate pursuits.   Fastest from the blocks: 0-60 mph Thirty years ago, any car that could clock 60 mph in five seconds or less was considered extremely quick. Today, high-performance, gasoline-powered sedans and SUVs are routinely breaking below 4 seconds. As of today, the 2023 Dodge Challenger SRT Demon 170 crushes all with a 0-60 mph time of just 1.66 seconds. That's simply absurd, but keep in mind the Demon was engineered with the single-minded purpose of going fast in a straight line. It's also important to realize that direct comparisons are difficult, because not all of these times were accomplished with similar conditions (prepped surfaces, adjustments for elevation and so on). The moral here is to take these times with a tiny grain of salt. After the Dodge, the Rimac Nevera comes in with an officially recorded 0-60 mph time of just 1.74 seconds. EVs crowd the quickest list, with the Pininfarina Battista coming in a few hundredths slower (1.79 seconds) than the Nevera and the Lucid Air sapphire (1.89 seconds) right after that. Eventually, you arrive to the Tesla Model S Plaid, which has a claimed 1.99-second 0-60 mph time, though instrumented testing by Car and Driver shows it accomplishes the deed in 2.1 seconds.

2014 Porsche 911 Turbo Cabriolet spotted testing in the nude

The Porsche 911 wouldn't be the Porsche 911 unless there were twenty-something different models to choose from (note: we are not complaining), and the latest one was just spied by our trusty photographers out on Germany's Nürburgring. Feast your eyes on the 911 Turbo Cabriolet - the droptop version of the new Turbo wonder that debuted in May - looking all sorts of stealth in its black-on-black-on-black prototype scheme.
Mechanically, the 911 Turbo Cab should be identical to the fixed-roof version, meaning a twin-turbo 3.8-liter flat-six engine will live in the car's rump, putting out something like 520 horsepower. Of course, there's also the hotter Turbo S version of the coupe, and we expect that to get the droptop treatment, as well, with 560 horsepower on tap. The added weight of the folding top and additional structural supports will likely make for slightly slower 0-60 times for both cars, though considering the base Turbo will hit 60 miles per hour in 3.2 seconds, "slower" is a very relative term indeed. All that force will run to the ground via all-wheel drive, managed by Porsche's seven-speed PDK dual-clutch transmission.
The wide stance of the 911 Turbo Coupe carries over to the Cabriolet, no doubt fitted with the same (standard) 20-inch wheels. Inside, the usual luxury amenities will be on hand, along with nearly endless customization options.
