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."

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.

Lexus RC F is a predatory sport coupe with a 450-horsepower beating heart

Take a look at that face. We can't be the only ones who see an automotive Predator staring back, right? Certainly, the Lexus RC F Coupe boasts a visually striking design that some are going to love and others are going to hate, but we can at least appreciate that it's aggressive, especially compared to the standard RC Coupe that we saw at the Tokyo Motor Show. And with good reason - there's a 5.0-liter V8 engine sitting under that massively domed hood with "more than 450 horsepower," along with a newly calibrated eight-speed automatic gearbox.
Interestingly, Lexus has tuned the RC F's engine to run on an Atkinson cycle under most circumstances, while it switches to the more typical Otto cycle when more power is required, presumably using some sort of advanced variable valve timing technology. Helping put that power to the ground with all those ponies wreaking havoc underhood is a torque vectoring differential, a first from Lexus.
Also involved in keeping the RC F planted is an aero package that includes wings and ducts galore. The headline bit is an active rear wing that deploys at 50 miles per hour and retracts back into the deck when the car drops back to 25 mph. A clear-coated carbon fiber roof can optionally join that carbon rear wing. There are apparently going to be three 19-inch wheel options, including the ones you see in our live image gallery above.
