Toyota develops new pre-collision system with steering assist

A number of automakers are working on developing fully autonomous cars, but it looks like the groundwork for such technologies will likely show up first as semi-autonomous systems for both safety and convenience. Following recent announcements from Nissan and Ford in this area, Toyota has now released information for some of its advanced semi-autonomous technologies that could be offered in production cars over the next few years.
On the safety front, Toyota's new pre-collision system with pedestrian-avoidance steering assist is aimed at protecting the folks who aren't in the car. This system combines visual and audible alerts with automatic brake assist and automatic steering. If warnings don't get the driver to slow down, the brake assist kicks in if a collision is very likely, but if that is still not able to avoid the impending collision (and if there is enough room to do so), the car can automatically steer itself around the pedestrian. This sounds most beneficial for last-second dangers such as a person accidently stepping out into the road in front of a car. Toyota hopes to have this technology available to customers by 2015.
The Japanese automaker is also testing a suite of technologies called Automated Highway Driving Assist (AHDA). The key part of this is a new adaptive cruise control system that uses vehicle-to-vehicle (V2V) communications rather than a radar-based system. This cooperative-adaptive cruise control allows vehicles to communicate their acceleration and deceleration data with other cars, which Toyota says this helps to improve fuel efficiency and traffic flow. Also a part of AHDA is the Lane Trace Control feature, which sounds like a next-gen lane keep assist. This system uses cameras, radar and a computer to keep the vehicle in a "smooth driving line" by being able to change steering angle, engine torque and braking force. Toyota says this technology could be in place by the "mid-2010s."

Lexus LC F prototype caught testing

The rumored Lexus LC F seems to be real based on these spy shots. A prototype was spied testing in Europe, and it shows a number of significant alterations from the regular LC 500 and LC 500h grand touring luxury coupes. In particularly, they seem to show a bit more of everything for the sporty edition. The nose bears some of the biggest changes compared with the standard models. While the center grille is mostly untouched, the outboard grilles have been cut wide open for more airflow. We can see the reason why, as there are heat exchangers in each of them. A particularly large one resides in the grille on the left side of the car. We can also see that the fenders have been extended over the wheel arches. Whether this is something to throw off observers or a final addition has yet to be seen, since the wheels and tires fitted to this car don't fill the added width, and the rear fenders aren't any wider, either. While nothing has changed to the sides of the car, we can spot the LC F's new brakes. They feature cross-drilled rotors and some beefy calipers. Moving around the back, we see that the LC F will get the signature stacked exhaust seen on the RC F and old IS F. Underneath, the tips will be matched with a wide diffuser that looks rather functional. Based on a previous report, it sounds like the LC F is still a couple of years away. Not much is known about the car, but it's safe to say it will make more than the 467 horsepower of the LC 500's naturally aspirated 5.0-liter V8. It could possibly have a twin-turbocharged 4.0-liter V8 or some sort of hybrid powertrain. To play in the same arena as some of the luxury performance competition, it will probably need at least 550 horsepower. Also expect it to cost significantly more than the LC 500h's low-$90,000s price tag. Related Video:

2016 Lexus IS 200t Quick Spin

When Lexus revamped its IS sedan for the 2014 model year, the car polarized in terms of design, and offered bipolar driving experiences, trim to trim. The entry-level IS 250 used a 2.5-liter V6 that felt like a lightweight for the segment. The stronger 3.5-liter six, especially when tied down to a car with the F-Sport package and subsequent handling improvements, was more of a sporting thing. Thankfully, Lexus has replaced the base powerplant for the IS with an up-to-snuff turbo 2.0-liter four. I drove the newly christened IS 200t for a week – with that enhancing F-Sport pack – and found it to be a vast improvement. Modest-budgeted buyers with eyes for Lexus' edgy styling seem to be in good hands. Driving Notes If the "200t" part of the model name looks familiar, you've probably seen it affixed to the rear end of Lexus' new NX small crossover. Of course the IS is lighter than its crossover sibling. Meaning the directly injected turbo engine's outputs of 241 horsepower and 258 pound-feet of torque are more thrilling in this application. At more than 3,500 pounds, the IS 200t still isn't exactly rapid – Lexus rates the 0-60 time at 6.9 seconds – but the torque pop is enough to jet around town authoritatively. Being a newly minted engine and a Toyota-brand product, you'd expect the IS 200t to be class-leading (or right there) in terms of fuel economy, too. With ratings of 22 and 32 miles per gallon, city and highway, it isn't. Both the BMW 328i (22 City / 34 Highway) and the Mercedes-Benz C300 (25 City / 34 Highway) do better, and while making similar power. The eight-speed automatic transmission is quite well suited for the brand and the car, I'd say. It mostly stayed out of my way, while in D, shifting unobtrusively during normal driving. The paddle-shift option is great for the occasional flights of motive fancy, but it's not lightning-quick, nor super engaging. Handling is nippy with the F-Sport package, at least within the normal boundaries of public roads. The car stays neutral and flat under cornering loads, and the front end feels rather light and quick to turn in. Of course, take the same corners more aggressively, and you'll feel the car default to understeering, with power cut on exit until all four wheels are fully set and gripping. Don't expect to slide the IS around, in other words. The chunky steering wheel feels good in the hand, and doesn't have the unsettling lightness I remember from the last-generation IS 250.
