Infiniti went out of its way to make the QX30 not a Mercedes

You can complain all you want about perceived badge engineering when a company (like Mercedes-Benz) sells a platform to another brand (such as Infiniti). The reality is that most buyers won't know the difference, and they won't even realize their Infiniti is really a Mercedes underneath or that their neighbor's GLA has the same basic parts as the QX30 they just bought. What's weird to me isn't that sameness, but the places where the two cute little utes differ. These two vehicles, which are more like tall hatchbacks, use the same Mercedes 2.0-liter turbo four and seven-speed dual-clutch transmission. Infiniti adds its own throttle and transmission calibrations. The suspension design is the same, although there are tuning differences. Both come standard with front-wheel drive, with all-wheel drive an option. Fuel economy matches for the FWD models, while the AWD Infiniti lags behind the Mercedes for some reason. So they're very similar despite their different looks. And design makes sense as a point of differentiation. Frankly, they go further than a lot of vehicles on shared platforms do – further, in fact, than the upcoming Nissan Navara-based Mercedes X-Class pickup does. The QX30 has its own sheetmetal and glass to separate it from the GLA-class. You probably think one looks better than the other. If you know where to look, the signs of sameness are obvious. Most major systems and pieces are shared, like the steering wheels (with different center covers), most switchgear, and things like interior and exterior door handles. Shared parts are fine as long as the parts are good ones. On that note, how many Tesla buyers realize their steering column and stalks, plus the window switches, come from Mercedes? And does that actually matter? We'd argue no. About those differences. Many are functional, like the fact the Infiniti does not carry over the Benz's Brake Hold feature – when you roll to a stop in the GLA (or any other Benz), pressing the brake pedal firmly applies the electric parking brake until you hit the gas to move again. The QX30 has an electric parking brake, but no Brake Hold feature. Someone used to driving Mercedes models will look a bit silly standing on the brake pedal to no effect. Ask us how we know. The Mercedes gauge package is carried over, but with the Infiniti font. Makes sense, although it's off-putting at first if you've seen the original, prompting a weird deja vu. Circular dash vents are replaced by rhomboid ones.

Infiniti QX Sport Inspiration Concept fits perfectly in the QX50's shoes

If there was any doubt about whether the Infiniti QX Sport Inspiration Concept is a preview of the next QX50, the official details presented at the 2016 Beijing Motor Show should erase them. The concept is smaller – a lot smaller – than the last QX70. And despite a recent update to the QX50, the brand's midsize crossover is due for a new model. We're basing that statement on dimensions. The QX Sport Inspiration Concept rides on a 110.2-inch wheelbase, and is 181.1 inches long, 74.8 inches wide, and 65 inches high. The last QX50, meanwhile, rides on a 113.4-inch wheelbase, and is 186.8 inches long, 71.0 inches wide, and 62.7 inches high. Ignore the different lengths – the concept's front and rear overhangs are remarkably short and aren't likely to translate to production – but the wheelbase, width, and most importantly the height, present a footprint that's remarkably similar to the QX50. Combine that with our assessment of the QX Sport Inspiration Concept's styling, and it's a virtual certainty that we're looking at the QX50's successor. As we said yesterday, the high beltline, tight greenhouse, long hood, and aggressive headlights are all trademarks of both the QX50 and QX70. Infiniti didn't say what kind of engine is under this concept car's hood (if there even is one – it might just be an engineless shell), but we're almost certain it's something performance-oriented. That would prove true if and when a new production QX50 is unleashed. We're betting the company will opt for the increasingly familiar setup of the new 3.0-liter, twin-turbocharged V6, a seven-speed automatic transmission, and all-wheel drive, like what you can get on the Q50 Red Sport 400 and new Q60. With 300- and 400-horsepower versions of this engine available, it could signal an introduction of a two-tier QX50 lineup. We're getting ahead of ourselves, of course. The QX Sport is still only a concept, but Infiniti's latest information dump at the 2016 Beijing Motor Show serves as even stronger evidence that its CUV lineup will grow back to four vehicles sooner rather than later.

2016 Infiniti Q50 Eau Rouge Prototype [w/video]

It only takes about half a lap of the Millbrook Proving Grounds for me to become convinced that Infiniti must build this car.
The sedan I am piloting around the English circuit is a working prototype of the Q50 Eau Rouge Concept that made its world debut at the 2014 Detroit Auto Show earlier this year. As a refresher, the exquisitely painted, burgundy metallic, four-door show car is based on the production Q50, enhanced with Infiniti Red Bull Racing-inspired carbon-fiber bodywork, aerodynamic upgrades and - as we would come to learn at the Geneva Motor Show a few months later - fitted with a beastly twin-turbocharged engine shared with the parent company's spectacular Nissan GT-R.
Despite lacking the concept's gorgeously expensive paint, the vinyl-wrapped red prototype seen here is much more appealing than the static concept, as it is mechanically complete - it can be driven - thus explaining why I have traveled one-third of the way around the world to test this enthusiast-tuned, one-of-a-kind machine at one of Europe's premier testing facilities.
