Toyota introduced a new C-HR Concept (its proportions place it between the B-SUV and C-SUV segments) at the 2015 Frankfurt motor show. The 2015 version follows on the first C-HR Concept, a 3-door concept introduced in 2014 at the Paris motor show. Featuring a 5-door cabin, this new design study is more closely representative of the compact crossover which is now confirmed for production; the final production model will be revealed at the Geneva show next year.
The new C-HR Concept was designed around a new platform, developed under the TNGA (Toyota New Global Architecture) program (earlier post), with a focus on handling and controllability, and features a new, advanced, full-hybrid powertrain.
Toyota New Global Architecture (TNGA) Platform. TNGA is an integrated vehicle development approach for powertrain components and platforms being introduced on new Toyota models from this year forward.
TNGA manifests itself in the new C-HR Concept through an increase in body rigidity, better collision performance, improvements to the vehicle underbody and suspension, and a lowering of the center of gravity.
Acting in conjunction, higher body rigidity and a lower center of gravity reduce body movement and vehicle roll when cornering. This allows for a reduction in suspension stiffness and a resultant increase in ride comfort with no detriment to driving dynamics, equipping the C-HR Concept with the responsive handling, agility and straight-line stability on a par with the best C-segment hatchbacks.
Incorporating a set of new production techniques and technologies that will make it easier to turn vehicle designs and features into production reality, TNGA groups vehicle development to promote a strategic sharing of parts and powertrain components. This approach will reduce the resources required for development by 20% or more, freeing up investment for improved product strengths and advanced technology development for sustainable growth.
Hybrid System. The hybrid system in the 2015 C-HR is more compact and with lighter componentry. It reflects significant advances in battery, electric motor and gasoline engine technologies, offering further reductions in fuel consumption and CO2 emissions.
As with the hybrid system in the new 2016 Prius—the first global production vehicle to implement Toyota’s New Global Architecture (TNGA) (earlier post)—the C-HR hybrid system operates in synergy with a gasoline engine featuring thermal efficiency of more than 40%. New battery technology with new, highly-compact electric motors offer a marked increase in power density.
More compact, lighter in weight and more efficient than Toyota’s current hybrid systems, the new full-hybrid powertrain developed under the TNGA program will also be more refined, and even easier and more intuitive to drive, with a natural, smooth and immediate response to driver inputs.
Global Project Rooted in the European Market. The new C-HR Concept is another tangible application of Toyota’s new Global Vision thinking, first advocated by President Akio Toyoda in 2011.
Recognizing that Europe is the most demanding market for small and mid-sized vehicles, Toyota uses this region as benchmark for defining future global A-, B- and C-segment cars. Toyota Motor Europe (TME) has also become the company’s skill centre for perceived quality and vehicle dynamics.
In the case of the C-HR Concept, there was close cooperation between Toyota’s vehicle planning centers in Japan and in Europe to get a good understanding of the latest European customer demands and vehicle trends. The styling of the concept car is the result of a global cooperation between ED2 (European Design Development Center) and the other Toyota design centres.
TME will continue to work hand in hand with TMC (Toyota Motor Corporation in Japan) to enter the C-Crossover segment.
