Toyota mulling Cummins diesel for Tundra?

When Bloomberg spoke to Toyota USA Sales CEO Kazua Ohara recently, we highlighted his comments on the possible return of the Toyota Supra. However, the interview started with Ohara discussing the Tundra, and how it would take time to pinpoint and hone the pickup truck's brand image in the minds of consumers. That effort could get a boost, with a report in Edmunds saying that Toyota is "evaluating" the addition of a Cummins turbodiesel to the Tundra's engine options.
The Cummins powerplant is one of two options for the moment, the other being a hybrid powertrain. If the oil-burner got the thumbs-up, Toyota would follow the recent example of Nissan, which announced it would put a Cummins turbodiesel into its 2015 Titan. While the two Japanese companies make a closer comparison since they're both talking about Cummins applications in light-duty trucks, if it happens, it could be seen as further diluting the once-exclusive tie-up that Ram trucks has had with Cummins even though Ram has used Cummins in its heavy-duty truck.
Toyota hasn't said when it will decide on which direction to take, but either will be a move for the better in the view of segment watchers; PickupTrucks.com said the first of its top-five fixes for the Tundra would be a better engine, perhaps a diesel-electric hybrid from Toyota's Hino unit. Cummins told Edmunds it can supply a second manufacturer with the 5.0-liter diesel that Nissan will be using, so we wouldn't be surprised to see it end up in a Toyota or somewhere else.

Toyota drops detail about 414-hp Hybrid-R concept powertrain

The Toyota Yaris Hybrid-R Concept has been teased already, offering up little glimpses and details of the Frankfurt-bound vehicle. And while those few, shadowy shots have been great, we've really wanted to know how this hatchback would deliver its promised 400-plus horsepower. Under hood sits a 1.6-liter, race-derived, direct-injection, turbocharged four-cylinder that powers the front wheels. Sounds peachy, but with 414 horsepower splashed across the page, we're going to need something more than a 1.6-liter, turbo four.
A supercapacitor, developed from the Toyota TS030 Hybrid Le Mans racer sits in place of a hybrid's traditional battery packs. The benefit, according to Toyota, is that power can be more rapidly absorbed and discharged than in a traditional battery system, like nickel metal-hydride.
The gas engine is joined by a trio of 60-horsepower electric motors. Two of the them power the rear wheels, while the third sits between the engine and the six-speed, sequential gearbox. Developing the same amount of power as the rear-axle motors, this centrally located motor channels power to the race-derived supercapacitor during braking, and ships extra grunt to the rear wheels under acceleration when the front wheels start to lose grip. Besides the distributive power of the central motor, the rear electric motors can adjust the amount of torque flowing to each wheel, much like a differential.

Toyota Yaris Hybrid-R zips in on its way to Frankfurt

Toyota has been known to make some exciting cars over the years, but its hybrids, well... let's just say a Prius appeals to a different kind of buyer. The TS030 Hybrid LMP1, on the other hand, now that's more our speed. And at the Frankfurt Motor Show next week, the Japanese industrial giant will bridge the gap with the concept car you see here. Previewed in bits and pieces along the way, Toyota has now revealed the full details and array of photos of its new Yaris Hybrid-R concept. And what the full picture reveals is a Prius C that's gone to the gym - or more appropriately, the track.
Powering this little pocket rocket is TMG's Global Racing Engine: a 1.6-liter inline-four with direct injection and a Garett turbocharger to drive 300 horsepower to the front wheels through a six-speed sequential gearbox. A pair of electric motors provide an extra 60 hp to each of the rear wheels for a combined output of 420 hp and through-the-road all-wheel drive. A third 60hp electric motor serves as traction control under acceleration and acts as a generator under braking to feed the TS030-derived super capacitor that boasts a higher power density and faster charge/discharge speed than a traditional battery. The system can provide a 40-horse boost for ten seconds in Road mode, or the full 120hp for five seconds in Track mode.
Though based on the three-door Yaris, there'd be no mistaking this for any ordinary econo-hatch. 18-inch TRD alloys with Michelin Pilot Sport Cup tires pack the wheel wells and a wider grille dominates the front fascia, while black and blue trim contrast sharply with the white bodywork. The rear pillar incorporates a quick-fill competition-spec fuel cap, LED daytime running lights illuminate the way and oversized brakes keep it all under control. The interior boasts Recaro racing buckets in black leather and blue Alcantara. There's more to digest in the press release below, but the bottom line is that if this is where Toyota is taking its hybrids, we want to climb into the driver's seat, and we're looking forward to seeing the concept in the flesh next week.
