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 NX debuts in turbocharged and hybrid guise

Lexus showed off its polarizing new NX at the 2014 Beijing Motor Show, trotting out both the turbocharged 200t model (Lexus' first production turbo) alongside the hybrid-powered 300h.
We still don't know a great deal about the turbocharged model, aside from the fact that the engine underhood is a 2.0-liter four-cylinder, although we're hoping to get details sooner rather than later. For reference, the 2.0-liter turbo in the BMW X1 pumps out 240 horsepower while the four-pot turbo in the Mercedes-Benz GLA250 turns out 208 horsepower, which leads us to think we should expect the Lexus to fall somewhere between these two figures.
If Lexus' naming strategy in the past rings true here, though, we can confidently say the 300h will use a 2.5-liter four-cylinder Atkinson cycle engine with an electric motor and lithium-ion battery, just like the Lexus ES300h and Toyota Avalon Hybrid. That should mean around 200 system horsepower and well over 30 miles per gallon, although it's probably too early to predict economy with any degree of certainty.

2015 Lexus LS gets tiny tweaks to try to keep up in LA

The 2015 model-year updates for the LS are certainly minor, but at least Lexus isn't letting its flagship sedan languish completely. The biggest change for the revised model is an improved infotainment system with an updated navigation and dynamic guidelines for the backup camera. Lexus' Enform App Suite also allows owners to remotely control some of the vehicle's functions, including the door locks, ignition and climate control settings. Among the litany of incredibly small tweaks, the dome lights now use LEDs, and the F Sport model that includes features like a sport-tuned air suspension and 19-inch forged wheels gets an added badge at the rear. The changes have increased the turning circle by 3.9 inches for models with the standard suspension and 18-inch wheels. All of the changes are definitely minor, but hopefully they'll sustain the posh motor until its next iteration is ready. 2015 Lexus LS Shows Why This Luxury Flagship Became A Luxury Legend - New Multimedia System for 2015 - Lexus Enform App Suite Upgraded - Upgraded Backup Camera With Dynamic Gridlines - F SPORT Model With Special Suspension, 19-inch Wheels, Brembo Brakes October 16, 2014 History seems to be repeating itself. The Lexus LS upended the luxury segment a quarter-century ago, and one reason was that it made a powerful V8 engine standard when it was a very expensive extra-cost option in some European models and not even available in others. Just change the year to 2015, and the situation seems to be replaying. A supremely smooth, standard 386-horsepower 4.6-liter V8 teamed with an eight-speed automatic transmission is only one facet of the 2015 Lexus LS 460, though undeniably, it's the one whose benefit you feel quite strongly during a road test. Nearly silent acceleration remains a hallmark aspect of driving a Lexus LS, which also offers the option of a more engaging driving experience with the F SPORT Package. A wide range of model choices also make the Lexus LS a standout. The LS 460 comes in regular and long-wheelbase versions, each with the further choice of rear-wheel drive or all-weather drive (360 hp with AWD). The ultimate Lexus flagship sedan remains the LS 600h L hybrid with 438 total system horsepower from a 5-liter V8 paired with an electric motor and all-weather drive. New for 2015, the LS gains a new multimedia system. The multimedia system, accessed through the navigation screen, provides a multitude of capabilities.
