Bosch builds an infotainment system that just might not suck

As far as we've come with in-car infotainment and interfaces over the past decade or so, we still have a long way to go — as most current systems show. Whether it's high-end brands like Mercedes-Benz with its kludgy COMAND system, which we hope will be replaced with the MBUX platform revealed at CES, or more mainstream vehicles like Hondas (with their frustrating, knobless Display Audio interface), getting the kind of content and ease of use in the car that we're used to having on other connected devices is far too complex and sometimes costly. While Apple and Google have tried to ride to the rescue with CarPlay and Android Auto, respectively, they're limited solutions. No automaker or tech supplier has been able to deliver an easy, economical, flexible and non-distracting infotainment solution. But Bosch could be closing in on this elusive goal, given the digital cockpit concept demo I recently received at CES. Displayed in a Cadillac Escalade, the concept featured five interconnected color screens: one in the instrument cluster, two in the center console, and two more in the front-seat headrest for second-row passengers. The digital cockpit concept demo had cool features such as haptic-feedback touch-screen controls that created an edge-like feeling similar to a physical button, facial recognition to confirm driver credentials, and the intelligence to know the location of a phone in the car to lock it out to keep the driver from texting. The most significant aspect of the Bosch digital cockpit concept wasn't visible — but shows the company's vision for a future of seamless, convenient, cost-effective and safe in-car infotainment. It's powered by a single electronic control unit (ECU) that can simultaneously run multiple operating systems and also separates vehicle and infotainment controls for critical safety and cybersecurity reasons. Most modern cars can have as many as 100 separate ECUs, Philip Ventimiglia, product manager for Bosch Car Multimedia North America, explained at CES, and several just for infotainment functions. "The goal is to reduce that to about 10 so that we can save cost throughout the vehicle and enable new technologies," he added. "OEMs want to put more technology into cars, but it costs money," Ventimiglia said.

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).

Mercedes-Benz S-Class Cabriolet completes the luxury trinity

In its continuing bid to simply eat the lunch of the Bentley Continental GT, Mercedes-Benz has followed up on the S-Class sedan and coupe with a new S-Class Cabriolet. Aristocrats, take notice. Below the beltline, all is familiar. That means the same stylish sheetmetal, from the chiseled front fascia to the strong character lines to the pert rear end. Expect the cabin's accommodations to mirror the hardtop model. But the third member of the S-Class family differs above the beltline, where we see a sumptuous canvas roof. The three-layered top is, unsurprisingly, quite advanced. It uses a three-layer, acoustically optimized design that promises a quiet ride. The top can be dropped or raised in under 20 seconds and at speeds of 37 miles per hour. Finally, the addition of a canvas cover doesn't do much to the S-Class' aerodynamics, as the cabriolet still returns an impressive 0.29, which compares favorably with the 0.27 of the four-door model (the coupe's CoD isn't available). Opting for the S-Class Cabriolet will entitle you to some additional standard equipment, including Mercedes' AirScarf neck heater. The droptop will also pioneer the German brand's new Thermotronic climate feature, which takes complete control of the HVAC system and makes adjustments based on the findings of 12 sensors and 18 actuators. The sensors include those for interior and exterior temperature, solar radiation, air quality, and dew point, among others. Yes, your S-Class will have a sensor for the dewpoint. Also new to the S-Class Cabriolet – not to mention the S-Class line as a whole – is a 9G-Tronic nine-speed automatic transmission, which is already featured on the SLK-Class and the new GLC-Class. The new 9AT will be limited to the S550, while the new S63 Cabriolet will use the coupe's seven-speed AMG Speedshift transmission. Both engines, meanwhile, mirror their coupe counterparts, with 449 horsepower and 516 pound-feet of torque for the S550 and 577 hp and 664 lb-ft of torque on the AMG model, allowing the latter to hit 60 mph in just 3.9 seconds and reach a limited top speed of 186 mph. Both the S550 cabriolet and its Mercedes-AMG counterpart will make their global debut at the 2015 Frankfurt Motor Show, later this month. Read on for the full press release from Mercedes-Benz.
