Acura introduces a sleeker self-driving test car

As we creep ever closer to an autonomous-car future, one thing is for certain, most of the driverless cars we see being tested look hideous thanks to all the sensors strapped to the roof. Today Acura introduced its second generation Automated Acura RLX Development Vehicle with updated sensors and a more pleasing aesthetic. Gone is the spinning LIDAR system replaced with a more compact and robust version of the light detection and ranging technology. It's also got updated RADAR, camera, GPS and higher performance GPUs and CPUs as well as what Acura is calling "more intelligent software algorithms to support more complex testing scenarios." Acura and its parent company Honda have been testing autonomous cars at its GoMentum Station in the Bay Area since last year with a specially outfitted RLX (shown in the video above with the spinning LIDAR system). This new car will replace that vehicle. This article by Roberto Baldwin originally ran on Engadget, the definitive guide to this connected life.

2021 Hyundai Elantra vs. compact sedans | How they compare on paper

Despite the rising popularity of crossovers, the sedan market remains packed and fiercely competitive. It looks like it will stay that way with the introduction of the strikingly redesigned 2021 Hyundai Elantra. And since Hyundai was kind enough to provide plenty of specifications on the new car, we figured we ought to see how it stacks up to some of the latest and greatest small sedans on the market. For this comparison we picked the two best-sellers, the Honda Civic and Toyota Corolla, one of the other recently redesigned sedans, the Nissan Sentra, and a perennial enthusiast favorite, the Mazda3. Below you'll find a chart with all the raw numbers for your perusal. Following that will be our usual break down and analysis of the numbers and any other noteworthy features not included in the chart. Performance and Fuel Economy While the design and chassis are all-new on the Elantra, the base powertrain isn't. It uses a version of the naturally aspirated 2.0-liter four-cylinder shared throughout the Hyundai and Kia line-ups, and it's again paired with a CVT. With 147 horsepower and 132 pound-feet of torque, it's the second least powerful entry for conventionally-powered sedans, only ahead of the sluggish 1.8-liter base engine in the Toyota Corolla. For those looking for a peppy small sedan, the Mazda3's naturally aspirated 2.5-liter has the most power and torque, even ahead of the turbocharged Honda Civic's 174 ponies. On the other hand, the Elantra, which Hyundai says will have better fuel economy than the outgoing model, should get at least 36 mpg combined, and probably better, making it the most efficient non-hybrid of this group. For the best blend of power and efficiency, the Civic is likely the way to go, as its turbo engine can return 36 mpg combined in lower trims. If you want a manual transmission in this body shape, only the Civic and Corolla offer it. A manual transmission is available on the Mazda3 hatchback, and the turbo Civic can also be had with a manual in hatchback or Si forms. A new powertrain for the Elantra is the hybrid. It's unique compared to other hybrids in that it's coupled to a six-speed dual-clutch transmission, rather than an electronically controlled CVT (which is not the same thing as a CVT) or something too complicated to describe in this sentence (the Honda Insight).

Is the original Acura NSX a perfect supercar?

The long-awaited arrival of the second coming of the Acura NSX has naturally brought with it many deep retrospectives on the first Acura NSX. Xcar is the latest with a stint in the time capsule, lining up three NSXs to sample at a track in the UK. There's the red wonder that started it all, the standard aluminum-bodied car that went on sale in 1990, so simple and easy-to-drive, extracting more joy than many thought possible from a 3.0-liter V6 with 'just' 270 horsepower and 210 pound-feet of torque. The 25-year-old exotic shows its years, but mostly because of an automatic transmission that dampens throttle response and doesn't like changing gears. The praises it earned in the day, however, still remain, namely excellent steering, handling, and feedback. After that comes laps in the first NSX Type R, the model that lost more than 250 pounds by having no air conditioning, sound deadening, or stereo, and lightweight tweaks like carbon seats and thinner glass. Although it the tuning makes it much harder, the presenter wants to know, "Why isn't Honda making a car like this today?" Then there's the 2002 model, the one that would only last three years before closing the door on a fifteen-year run. It got better at the same time as it got softer, but by then the NSX had nothing left to prove; it hit every one of its targets, it realigned the segment in ways we're still benefiting from, and for at least half of its run nothing else could touch it. Based on the reviews so far, that might include the brand new, very good and very complicated NSX. Check out the video above for Xcar's take.
