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 looking for performance with 600-hp LF-LC?

Lexus has been keeping development of the production version of its LF-LC concept tightly under wraps. Last we heard, that halo GT car had received the green light for production, but that was over a year ago. Since then, things have been pretty silent. Finally though, fresh rumors about the luxury coupe are starting to leak out, pointing toward the model's powertrain lineup.
According to unnamed sources speaking to Motor Trend, the production LF-LC will eventually sport three very intriguing engine options. The base model will reportedly use a naturally aspirated V8 providing around 450 horsepower - very similar specs to the upcoming RC F. The next step up will allegedly be the upcoming hybrid powertrain shared between BMW and Toyota pumping things up to around 500 hp. Finally, a top-of-the-heap F version will use a twin-turbocharged version of the RC F's 5.0-liter V8 to bring output to 600 hp. The insiders even claim that the hybrid and the twin-turbo V8 could find their way into other Lexus products like the LS and possibly even a more beastly RC.
None of this speculation sounds too outlandish. Lexus could get more capacity out of the RC F's tuned V8 by shoving it into other models, and rumors are flying about performance cars spawned from BMW and Toyota's partnership. Given Lexus' recent embrace of turbocharging, even the twin-turbo V8 doesn't seem too dubious. That said, with no hard facts to back up the rumormill, we'll have to keep waiting to see what the LF-LC shows up with.

The revolutionary Bose suspension that could have been

The Bose name pops up on these pages every once in a while – usually, as you might expect, because some automaker or another has installed its audio systems in one or more of its models. But a few years back, the research-driven audiophiles at Bose developed a revolutionary adaptive suspension system that could have been a game-changer. Sadly, it wasn't. The Bose suspension system was a technological breakthrough. As you can see from the pair of Lexus LS sedans demonstrated (and the Porsche Cayman thrown in for good measure) in the two-minute video above from CNET, the system virtually eliminated body roll and smoothed out bumps in the road to near glass-like serenity. It could even jump over minor obstacles. Unfortunately, the system was too heavy and expensive to put into production, and the project was shelved. Instead, it was repackaged into a suspended driver's seat for heavy-duty, long-haul trucks and called the Bose Ride System. It's said to significantly reduce fatigue and back pain while encouraging driver alertness and wellness – which is all well and fine, but a far cry from what the suspension system could have meant for the automotive industry. Just think about that the next time you notice the Bose logo on the speaker grille in an upscale vehicle from the likes of Audi, FCA, GM, Mazda, or Nissan – all automakers that offer Bose audio systems, and which might have considered implementing the advanced suspension if only it were more practical for production.
