Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

Lexus RC F glows with your heartbeat

It's not uncommon to see all manner of sensors being installed inside new cars these days, monitoring everything from ambient noise to our levels of alertness. The question is what the automakers will do with the information gathered by those sensors, and we've seen some fairly novel innovations. This latest solution from Lexus may not be the most useful, but it's definitely one of the most interesting we've seen to date. The Japanese luxury automaker's Australian division cooked up this special RC F show car with a heart-rate monitor and a special electroluminescent paint job. The sensors detect how fast the driver's heart is beating, and displays it accordingly down the side of the car's flanks. In daylight it looks like it's painted plain old ordinary silver, and otherwise it's the same luxury muscle coupe we know, with a 5.0-liter V8 churning out 467 horsepower in resolute defiance of the downsizing/turbocharging trend that's sweeping the industry. The project was cooked up by creative agency M&C Saatchi and uses glow-in-the-dark paint from American specialist Lumilor. The vehicle is set to be unveiled over the weekend, but you can scope it out now in the images below and the preview video above. Is it pointless? Almost entirely. Does that make it any less cool? Of course not. 22 July 2015 LEXUS GETS PULSES RACING WITH WORLD'S FIRST HEARTBEAT CAR Lexus Australia has developed the world's first vehicle to display a heartbeat on its exterior in a demonstration of advanced technology and the connection between man and machine. The Japanese luxury marque collaborated with creative agency M&C Saatchi to produce a one-off RC F V8 coupe that integrates a series of technologies to display a person's heartbeat in the vehicle's bodywork. The first stage of the system works by transmitting the heartbeat of a connected person from a heart rate monitor to a bespoke electrical system in the RC F. The on-board system captures and processes the data before sending an electric charge through the RC F's body panels that are painted in electroluminescent paint developed by US-based specialist Lumilor. This innovative paint finish glows when the electrical charge runs through it and displays the person's heartbeat via a real-time animation sequence. Lexus Australia chief executive Sean Hanley said the heartbeat car comes in the wake of other innovative brand activities in 2015 and an ongoing commitment to the development of high performance Lexus F vehicles.

Toyota, Lexus will offer low-cost automated braking system

First, a technology gets better, then it gets a lot better, then it gets less expensive, then it gets a lot less expensive. Advanced driver safety and convenience systems are about to make that last step thanks to Toyota. Centered around a pre-collision braking system, there will be three suites of driver aids known as Toyota Safety Sense C (TSS C) for compact cars, Toyota Safety Sense P (TSS P) for midsized and premium cars, and Lexus Safety System+ (LSS+) for the luxury brand. TSS C pairs a camera with laser radar to provide a pre-collision system that prompts the driver to brake if it detects an impending accident, and can supply additional braking force and automatically brake between seven and fifty miles per hour. There are also Lane Departure Alert and Automatic High Beam. TSS P pairs a camera with more precise millimeter-wave radar. Starting with the three functions in TSS C, it adds pedestrian pre-collision capability and adaptive cruise control. This one will be available first, coming on the new RAV4 Hybrid and Avalon. TSS - either C or P - will expand to three more vehicles by the end of the year. The wallop is in the price: TSS C will be a $300 option, TSS P will cost $500. Compare the Ford Fusion SE, for instance - it's Driver Assistance Package comes with Lane Departure Warning, Automatic High Beams, it has Lane Keep Assist, Blind Spot and Cross Traffic Detection that neither TSS has, but doesn't have any autonomous braking feature. It costs $1,200, but requires you to add the Technology and Luxury Packages for a total price of $3,165. If you want Autonomous Cruise Control, that's another $995, for $4,160 in total. Instead of $300 or $500 on the Toyota. Lexus' LSS+ will come first on the new RX then spread to four more models by the end of this year, and cost between $500 and $635 to add as an option. It also uses a camera and millimeter-wave radar for its vehicle and pedestrian pre-collision system, lane departure warning and lane keep assist, automatic high beam, and auto cruise control. The similar package on a BMW X5, with no pedestrian component, is $1,200. Toyota says both safety suites will eventually be on "nearly all" of it products and all trim levels by the end of 2017.
