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).

Jaguar's electric speedboat smashes decade-old record

We knew Jaguars prowl on dry land, but apparently they dabble with water, too. Jaguar teamed up with powerboat racing specialist Vector and Williams Advanced Engineering to beat the existing British and world records for fastest battery-powered boat with some expertise from Jaguar's Formula E team. The team had to top 76.8 mph, a record set in 2008 by Helen Loney in her Firefly electric hydroplane with Agni motors. The attempt was made in the same location, Coniston Water in the English Lake District, where speedboat record runs have been made since the days of Sir Malcolm Campbell as early as the 1930s, and son Sir Donald Campbell into the 1950s and 1960s – including the fateful record attempt that cost the younger Campbell his life in 1967. The company's documented the attempt in the video shown above. It reveals that the 2008 record wasn't easy to beat. At first, pilot and Jaguar Vector co-founder Peter Dredge managed to get the boat to 76.6 mph – annoyingly close to, and just under, the record. But a later run rewarded the team's efforts, with a clear improvement of nearly 12 mph, making the new record 88.61 miles per hour. This achievement is also impressive considering that Jaguar and Vector only announced their partnership in October 2017, so progress has been swift. The tech in the boat is reportedly derived from Formula E technology, though Jaguar Vector and Williams Advanced Engineering have not disclosed the boat's exact specifications nor what parts are based on Jaguar Formula E car parts.

Jaguar's Callum: 'Huge' opportunities with electric vehicles

Eventually, some brave innovator, with an imagination light years ahead of the rest of us mere mortals, will envision an automotive future that the rest of us can't conceive. This person will step up and tell us how electric vehicles have the potential to change our lives for the better. They'll have the guts to tell us that if we could only open our eyes, we'd see that there's a way to get from one place to another that doesn't pollute the air we breathe. They'll explain that it won't just be globally responsible, it'll be magnificent. Yes, the electric car needs a champion, a figurehead, someone so inspirational that comic book superheroes are modeled after him. Finally, that champion has revealed himself. Saying out loud what the enlightened few of us know but dare not utter for fear of ridicule, our hero has spoken. "Electrification will kickstart the biggest change in automotive design in history," Ian Callum, design director at Jaguar told Autocar. That Jaguar sees the potential for electric vehicles is welcome progress. Sarcasm aside, that Jaguar sees the potential for electric vehicles is welcome progress. Even more appealing is that Callum approaches the potential of EVs from a design angle, where the slate is essentially blank, he feels, and so much is possible. "The opportunities an electric powertrain offers are huge," Callum says, "especially in terms of the space for occupants. By removing so much of the mechanical hardware and placing the batteries in the floor plan you open up all sorts of possibilities with packaging." To peer into Callum's mind when it comes to EV design would be extraordinary to behold. In many ways, his vision truly is something most of us cannot grasp completely, having spent a long career designing some of the most desirable cars of our time for some of the most prestigious automotive brands on the planet. So when he talks about the freedom EVs present from a design standpoint, it's not difficult to get excited. A Jaguar EV isn't as far-fetched as it might seem at first. Plus, a Jaguar EV isn't as far-fetched as it might seem at first, as Callum explains. "I'm clear in my mind that an electric Jaguar would be suitable for the brand," he says. "You have to move with the times and design for the opportunities. Look at the C-X75 concept – that was a car that was designed for an alternative powertrain, and nobody had any complaints about how that looked.
