Cadillac previews upcoming new XT5 crossover [UPDATE]

UPDATE: Cadillac has released another three images, which we've added to the gallery above. Cadillac is gearing up to unveil its new XT5 crossover at the Dubai Motor Show in November. We've already seen what it'll look like - from a couple of angles, anyway - but the all-American luxury automaker has given us another taste of what's to come with a quartet of images released on its official Facebook page. Set to replace the SRX that's now six years old, the all-new XT5 adopts the new design language we've seen on newer Cadillacs of late. That's most particularly emphasized with those vertically integrated LED headlights. The sharply creased styling is also signature Cadillac, as is the egg-crate grille capped by the brand's wreath-less new emblem. The dark brown paint job also looks like it has a deep metallic flake to it, offset by satin brightwork where you might have once expected to see glinting chrome. (Then again, it could just be reflecting a uniform backdrop.) The XT5 is expected to be the first of several new Caddy crossovers to wear the letters XT. A smaller model (likely to be dubbed XT3) is tipped to slot in below, with a larger XT7 to slot in above – but still below the defiantly truck-based Escalade that's not about to go anywhere anytime soon. Sedans will continue to start their nameplates with the letters CT. But after a dozen years, the letters SRX will be retired from the Cadillac lexicon. Related Video:

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).

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.
