Comma.ai makes your car semi-autonomous for $999

At TechCrunch's Disrupt conference in San Francisco, Comma.ai founder George "Geohot" Hotz announced the launch of the Comma One semi-autonomous driving device. Hotz said at the conference that his company has worked on the Comma One for about a year, and it will be available at the end of the year for $999 and a $24 per month subscription fee. But aside from the reasonable price, which TechCrunch points out is possible thanks to off-the-shelf components, the appeal here is that it's an add-on to an existing car that can be installed at home by the car's owner. This gives people with normal cars the opportunity to have semi-autonomous features without having to buy an entire vehicle... that is, if you have a Honda or Acura with lane-keeping assist, since Comma One is currently only compatible with those vehicles. It remains to be seen if the company will add more vehicles to the list over time. The device is roughly the size of a large cell phone or aftermarket navigation system, and it has a screen on the front and a pair of cameras on the back. The computer combines information from the device's cameras and the car's radar sensors to understand what's happening and how to respond. Hotz explained at the conference that this system is similar in capability to the Tesla Autopilot system, and will be able to complete a drive, start to finish, without the driver having to touch anything. He did however emphasize that the driver must still pay attention in the event something goes wrong, comparing the experience to watching a young student driver. Hotz told TechCrunch that the device should start shipping at the end of the year. He also said that owners of compatible Honda products in the San Francisco area are eligible for beta testing, and can get involved by emailing him at george@comma.ai. So if you've been pining for a semi-autonomous vehicle of your own, but couldn't spring for a Tesla, you won't have to wait much longer. We should point out that we don't know yet how well the system works, though we hope to find out soon. Related Video:

2018 Acura RLX refresh packs a new face and NSX DNA

The redesigned 2018 Acura RLX is here, and it's the fastest and most capable sedan the company has ever built. While not all new, there's a host of changes both inside and out, through the two powertrains carry over unchanged. The RLX Sport Hybrid packs a bit of NSX DNA to go along with the new family face. The car will make its full reveal next week at Pebble Beach before it hits showrooms later this year. The first Acura RLX debuted in 2013 as a replacement for the range-topping RL sedan. Sales have been slow, though a slimmed down lineup may help that. Powertrains remain the same, but refreshed styling and the removal of the controversial "beak" grille may help bring in some new blood to Acura dealers. The car comes in two variants, the 310 horsepower RLX with Precision All-Wheel Steer (P-AWS) and the 377 horsepower RLX Sport Hybrid with Super Handling All-Wheel Drive (SH-AWD). That's a lot of acronyms, but there's a lot of tech behind those names. Both models use a 3.5-liter direct-injected V6, though the Sport Hybrid backs that up with three electric motors. It's a similar setup to the Acura MDX Sport Hybrid that we drove in the spring. The RLX P-AWS now sends power to the front wheels through a new 10-speed automatic. Both models get new styling, following on the heels of the updated Acura TLX. The beak is gone, replaced by what Acura dubs the "diamond pentagon" grille. It's handsome and sure to be less divisive than before. In addition to the grille, the RLX gets a new hood, new wheels, and new lighting, with a sea of LEDs lighting up the face. The 2018 model gets three new paint colors to go along with the new bodywork. The RLX Sport Hybrid sits atop the Acura sedan range. As such, standard features include a Krell Audio System, surround view cameras, parking sensors, LED fog lights, remote engine start, ventilated and heated front seats, and heated rear seats and steering wheel. The RLX is available with the AcuraWatch suite of active safety technology. Similar to HondaSense, AcuraWatch comes with automatic emergency braking, lane keeping assist, lane departure warnings, forward collision warnings, adaptive cruise control, and low-speed follow. Unique to AcuraWatch is traffic jam assist. This system works with the adaptive cruise and low speed follow to keep the vehicle moving and following at a set distance in heavy traffic. Look for more photos and pricing later this year.

2017 Acura MDX Sport Hybrid goes on sale in April for $52,935

If you like the hybrid tech of the Acura NSX, but don't need a six-figure, 191-mph supercar as your daily driver, you might enjoy the extra room of the Acura MDX Sport Hybrid. It uses the same SH-AWD system with three electric motors as its racier stablemate – and puts a naturally aspirated 3.0-liter V6 up front – but seats up to seven people. It goes on sale in early April, and Acura has announced a starting MSRP of $52,935. The MDX Sport Hybrid starts at $7,910 higher than the base, front-wheel-drive MDX, but only $1,500 more than the comparably equipped, non-hybrid MDX SH-AWD. It offers 31 more ponies, for a total of 321 peak horsepower and of 289 pound-feet of torque. It's less expensive than the other Acura to use the Sport Hybrid system, the RLX sedan, which starts at $59,950. (That car incurs a price premium of $5,500 over its P-AWS-equipped FWD base model; there's no non-hybrid AWD RLX.) The MDX Sport Hybrid gets an EPA-rated 26 mpg city, 27 highway, and 27 combined. Compared to the conventional MDX SH-AWD's 18/26/21 mpg rating, its biggest fuel economy gains are to be found in city driving. The Sport Hybrid's figures are even slightly better than the 25/26/26 mpg Acura expected when the car debuted in New York last year. The MDX Sport Hybrid should be fairly entertaining to drive, too, at least for a utility vehicle. It's Acura's most powerful SUV to date, and it offers four driving modes: Comfort, Normal, Sport, and Sport+. A seven-speed dual-clutch transmission handles the gear changes, but the driver can take control via a pair of paddles on the back of the steering wheel. The SH-AWD system's torque vectoring feature promises to help make the MDX proficient in the twisty bits, too. Related Video:
