2019 INFINITI Q60

 

The 2019 Infiniti Q60 is a beautiful luxury coupe that’s an alternative to staid competitors.

The 2019 Infiniti Q60 is focused more now on its mission as a luxury sport coupe.

This year, the coupe cleaved its turbo-4 engine from the lineup in favor of a twin-turbo V-6 only menu, offered in two tunes.

 

 

We give the 2019 Q60 a 6.2 overall thanks to its good looks and sharper performance this year. (Read more about how we rate cars.)

Hyundai calls this concept Elevate, or the Ultimate Mobility Vehicle. We call it the ummmm … V. Hyundai

 

Like the sushirrito and the Rollie Eggmaster, the wheel is the certified product of the human brain, unmatched in ingenuity by eons of evolution.

Now, after 5,000 years of transportation advances built on the ability to roll from A to B, Hyundai has decided it’s time to move on. Today at CES in Las Vegas, the automaker fleshed out the details on an insect-like concept car that isn’t limited by its wheels. This thing also has legs, which allow it to go where there are no roads, by trekking or climbing over difficult terrain, fording rivers, clambering over crumbled concrete, or even climbing stairs.

In this city without restraint, CES is a safe space to showcase outrageous concepts unlikely to make it to production. But Hyundai has thought through a business case for the machine it’s calling Elevate, or the Ultimate Mobility Vehicle (how about the ummmm … V?). It pitches the blend of car, robot, and Mars rover as the ideal machine for first responders. While a car or truck would get stumped at the edge of a debris field of broken buildings, for example, the Elevate can just clamber on over, to the heart of the problem, instead of leaving firefighters or anyone else to trek in on foot. Hyundai says that, with a modular platform, the body atop the walking wheels could be swapped out for different applications. It also shows a taxi concept that can climb entrance steps to a building, to allow wheelchair users to roll in and out easily.

The platform itself puts the four wheels on the ends of robot legs with five degrees of freedom (meaning they can move in just about any direction). Propulsion comes from electric motors mounted inside each wheel hub, like on the Mars Curiosity Rover.

When the legs are folded under the vehicle, the Elevate can travel at highway speeds, almost resembling a normal car. But it looks cleverest, and scariest, when it rises up to full height, using the wheels as feet. It can replicate the walking patterns of both mammals and reptiles, so it can stride across most terrains confidently, even snow and ice, with the wheels turned sideways as nonslip pads. “Imagine a car stranded in a snow ditch 10 feet off the highway being able to walk or climb back to the road,” says David Byron, design manager at Sundberg-Ferar, the Detroit-based design studio that worked with Hyundai to develop the concept.

Concept is the key word. Hyundai is vague on whether this thing would be autonomous or require a human at the controls, but it’s worth noting just how hard moving a robot through the world really is. As Boston Dynamics CEO Marc Raibert said at last year’s WIRED25 conference, the robot shop’s viral videos—starring dancing quadrupeds and parkour-ing humanoids—showcase the rare successful attempts, not the many screwups along the way. And although the Curiosity Rover has lasted nearly three times its designed lifespan, on a hostile alien planet, it’s not a great model for a commuter machine: It has covered just 12 miles in six years.

If the promised revolution in mobility due to autonomous, electric, connected cars (and scooters) actually arrives, it will bring changes in the way that we use vehicles in cities. So although this concept it outlandish, it doesn’t hurt to start thinking about new ways to build vehicles, and maybe even reinvent the wheel.

It’s a better idea, anyway, than trying to cook eggs in a tube.

2019 Nissan Sentra Review

 

When it comes to compact sedans, the 2019 Nissan Sentra is a wallflower. It’s roomy enough for four adults, fuel efficient for its class, and packs just enough features to keep most buyers happy but fails to deliver on driving delight and design. We’ve rated it 4.8 overall as a reflection of its comfort, active safety features, value, but distinct lack of thrills. (Read more about how we rate cars.)

For 2019, the Sentra gets a few updates to keep it current, including a new 7.0-inch touchscreen for infotainment with Apple CarPlay and Android Auto compatibility on higher trims, and a new SV Special Edition package that adds worthwhile functional,  safety, and convenience features.

The 2019 Sentra is available in S, SV, SR, SR Turbo, SL, and Nismo trims, with the latter adding a plethora of performance features that don’t add up to an especially cohesive experience.

The 2019 SLC still sports the restyled duds it adopted for 2017, when it changed its name from SLK. The look’s wearing well enough. It’s better from the rear than from the front, where its tall nose stands out in relief from its gently tapered body. It’s better looking with the top lowered, but what convertible isn’t? The cabin’s similarly stuck between generations: The shapes and textures suit the SLC well, but myriad buttons and switches seem to have learned nothing from the smartphone revolution.

The SLC300 goes home to new garages far more often than the SLC43. We’d have it the other way around, but the turbo-4 in the SLC300 generates 241 horsepower and pushes it to 60 mph in 5.7 seconds via a 9-speed automatic. It’s plenty quick, but lacks the instant-on thrust of older V-6 SLKs. The SLC43’s twin-turbo satisfies deeply, with power uprated this year to 385 hp, sent through a tougher 9-speed to the rear wheels, with or without a limited-slip differential. With the diff and with a sport-tuned suspension, the SLC has higher limits to explore, and better balance, too—not to mention a faster 4.6-seconds 0-60 mph time.

The snug SLC cockpit has enough head and knee room for its two passengers, but leg room could be more generous. We’ll have more trunk space while they’re at it, and more in-car storage, too. The top’s quick action and unruffled top-down drive make up for some of those sins.

Facebook Inc.’s shareholders are poised to find out what long-time investors in other FANG stocks already know: They can’t count on higher prices every year. The social-media company, which fell 18 percent this year through Thursday, is headed for its first full-year decline since going public in 2012. The rest of the FANGs – Amazon.com Inc., Netflix Inc. and Google’s owner, Alphabet Inc. – all posted losses in 2014 and at least two other calendar years since their debuts. To be sure, Facebook slipped 30 percent from its initial public offering price in May 2012 through the end of that year.

The 2019 Nissan Versa is the cheapest way to get new-car smell and a full warranty, but rivals deliver plenty for not much more.

The 2019 Nissan Versa sedan and hatchback deliver a new car smell and three-year warranty at rock-bottom prices. The old maxim, “You get what you pay for” applies otherwise.

Overall, the 2019 Versa is good for 3.8 out of 10 on our scale. (Read more about how we rate cars.)

Every Versa uses a 1.6-liter inline-4 rated at 109 horsepower. A 5-speed manual is standard on sedans, but a continuously variable transmission (CVT) is a far more common option. The Versa has a soft, reasonably well-controlled ride. Acceleration is leisurely at best around town and highway passing takes a wide-open road.

The Versa’s tall body means it’s tossed around more in windy situations than most other new cars. Nicely weighted steering and an unladen curb weight of about 2,450 pounds mean it can be go-kart entertaining on a twisty road, but considerable body lean and narrow, fuel economy-oriented tires sap most of the fun.

The Versa sips fuel around town, but its engine works hard enough to make it less thrifty than most size-up compacts on the highway. Sedans are rated at a miserly 34 mpg combined.

Inside, the Versa is narrow and sparsely appointed. Its front seats are adequate and outward vision is good. Rear-seat passengers don’t have much leg room in sedans, but Versa Note hatchbacks have enough room for taller riders to be comfortable.
