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.

2021 Lexus LC 500 Convertible First Drive | Is less roof better?

The azure waters of the French Riviera are set ablaze by the setting sun as a cool breeze wafts in from the Mediterranean. The warm breath from the neck-level heaters commendably compensate. The 2021 Lexus LC 500 Convertible turns inland, the road winding through the rocky terrain like an ebony ribbon. A stunning blonde in a vintage Ferrari waves as she passes by; a man resembling Pierce Brosnan, but richer, gives a thumbs up. I'm sure someone is having this experience during their first drive of the new LC Convertible, but it sure isn't me. I'm in Scappoose, Oregon, which is as picturesque as it sounds. It's raining. Hard. An old woman in a Subaru pulls out of the Dutch Bros. So yeah, this won't exactly be a romantic tale of car and locale meeting on equal terms of grandeur. Resplendent in Flare Yellow paint, the LC Convertible couldn't be more conspicuous here if there were literal yellow flares bursting from its tailpipes. Yet, even on the Cote d'Azure, the LC would assuredly stand out. Being the color of an electric banana helps, but it’s a stunning car in any shade. From the A pillar forward, it's identical to the LC Coupe, but as expected, things change rearward. Currently available in two colors — black and "sand" — the four-layer soft top fits snugly over the cabin and creates a much different silhouette than the coupe. Although the LC's shoulder line rises to roughly the same point in both body styles, it meets a black trim piece on the coupe that creates the impression of a "floating" roof that extends deep onto the tail, resulting in a tiny trunk lid. By contrast, that shoulder line meets the convertible's roof directly, which pinches the rear quarter window, abruptly ends the roofline and creates a comparatively vast plain of a trunk lid. From the rear and with the roof up, the coupe is the more elegant car. Roof down, it's debatable. To these eyes, that rising shoulder line creates a bit of the hunchback look you get with the 911 Cabriolet. There are other design changes. The trunk lid kicks up further and extends wider, creating a more pronounced integrated spoiler. Within it is the relocated brake light. Covering the lowered roof is a rigid tonneau cover with humps that neatly align with the back seat's headrests. Between them is a small wind deflector that manages to be enough when the windows are raised to create an impressively serene cabin in the brief moments when the drizzle clears to motor al fresco.

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.
