Jay Leno's Garage drives Steve McQueen's 1956 Jaguar XKSS

Steve McQueen might be the coolest American male of the 20th century. With movies like Bullitt and Le Mans, McQueen established himself as the king of cool of his era, and on the list of actors you would pick for a fantasy racing team - he or Paul Newman are the natural first choices. The latest Jay Leno's Garage video highlights one of McQueen's most special cars - a 1956 Jaguar XKSS.
Just 16 XKSS models were made because a fire at the Jaguar factory halted production. It was meant to be a street version of the company's very successful D-Type racer, with a modified version of its 3.4-liter straight-six-engine and a four-speed manual gearbox. McQueen clearly had an eye for great vehicles. He drove his Jag around Los Angeles years after it was a cutting-edge piece of technology. Since then, it became part of the Petersen Automotive Museum in LA. Autoblog's The List even took a ride in it when the show visited the museum.
The XKSS is one of the pinnacles of automotive design of the '50s, and its association with McQueen makes this example even more extraordinary. Leno is in love with the car from the moment he sees it, and it's hard to argue with him. Between its emphasized curves and raspy exhaust, this is one sexy Jag. Scroll down to get an eyeful and earful from one of McQueen's favorite cars.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).

Land Rover will put a Covid-nuking air filtration system in future cars

Jaguar - Land Rover (JLR) is developing an air filtration system that inhibits up to 97% of viruses and airborne bacteria. Designed like a face mask for your car's HVAC system, it's built on Panasonic's Nanoe X technology. Most of the company's models (including the Land Rover Defender) currently come equipped with Panasonic's Nanoe technology and PM2.5 filtration. Nanoe X is 10 times more effective, according to the brand, because it relies on a high voltage to create trillions of hydroxyl (OH) radicals enveloped in nano-sized water molecules. Think of them as Roman guards in front of a fortress: they keep the bad out, and ensure only the good can come in. Viruses and bacteria proteins are denatured when they come into contact with the filtration system, meaning they can't reproduce or grow. The OH radicals also zap common allergens and mold, but they're harmless to humans. JLR stressed it's not relying on computer simulations to decide whether its filtration system works as designed. It asked British laboratory Perfectus Biomed to perform a test that simulates a ventilation system in recirculation mode for a 30-minute cycle in a sealed chamber. The results were encouraging: 97% of viruses and airborne bacteria were nuked. The carmaker pointed out Panasonic's Nanoe X technology has been independently proven to inhibit 99.995% of coronaviruses during a two-hour laboratory test carried out by French immunology lab Texcell. Future models from Jaguar and Land Rover will use this technology, though a representative for both companies declined to tell us when it will reach production, and which nameplate(s) will inaugurate it. Meanwhile, Honda launched its own coronavirus killer across the pond. It's a cabin air filter sold as a genuine replacement part that consists of four layers, including one coated with an active substance of fruit extract that inactivates nearly 100% of the viral aerosols it captures. It's available in Europe through Honda dealers, but it won't be sold in America. Jaguar Land Rover
