We’ve waited and waited for a Japanese car manufacturer to bring a clean diesel engine to the USA market, Mazda’s long-awaited clean diesel is finally coming. They announced Thursday at the L.A. Auto Show that the all-new 2014 Mazda6 will be offered with a SKYACTIVE-D 2.2-liter diesel engine. The diesel-equipped version will arrive at dealerships in the second half of 2013. There are no EPA fuel efficiency numbers available yet, but Mazda says they are targeted to be “class leading.” Mazda will be the first Asian manufacturer to offer the U.S. public a modern-technology clean-diesel engine. The 2014 Mazda6 also will also feature Mazda’s new capacitor-based brake energy regeneration system called i-ELOOP.
“We’ve dangled the carrot long enough and we couldn’t be more excited to officially introduce North America to our latest next-generation product, the 2014 Mazda6…” said Jim O’Sullivan, president and CEO, Mazda North American Operations. He continues: “…our Los Angeles announcements are only tips of the iceberg. The best is yet come.”
The Maxda6 will be available with a choice of either the SKYACTIV-Drive six-speed automatic or SKYACTIV-MT six-speed manual. As we mentioned above, Mazda says the fuel efficiency numbers will be “class leading.” The most efficient non-hybrid mid-size sedan is currently the Volkswagen Passat TDI with 31 MPG city and 41 MPG highway.
The new SKYACTIV-D 2.2-liter clean diesel engine offers an impressively low compression ratio of 14:1. This allows the engine to burn cleaner and it will not require any additional NOx after-treatments, unlike many other modern diesels. Performance estimates for the SKYACTIV-D clean diesel engine are not yet available. The SKYACTIV-D is expected to offer a high amount of torque.
The engine is 10 percent lighter than the MZR 2.2-liter diesel engine that Mazda offers in other global markets. Other improvements mentioned by Mazda include a 20% reduction in internal engine friction and improved fuel economy. This is achieved by using a new two-stage turbocharger, which delivers a steady response across the full 5,200-rpm engine range.
The Mazda6 will offer an all-new safety component called Smart City Brake Support (SCBS). It is designed to help drivers avoid front collisions when traveling at speeds of less than 20 miles per hour. An imbedded laser sensor will detect objects in the car’s path and will reduce the brake rotor travel to quicken braking if the system calculates that there is a risk of collision. If the driver fails to perform an avoidance maneuver, the SCBS automatic braking function will be activated.
i-ELOOP, Mazda’s capacitor-based brake energy regeneration system, collects energy as the vehicle decelerates, and then uses this energy to provide power to all electrical mechanisms in the vehicle. Unlike systems used in hybrid vehicles, i-ELOOP does not need a dedicated electrical motor and battery, making the system more efficient, compact and lighter than traditional systems. i-ELOOP is expected to improve overall fuel efficiency.
Pricing for the 2014 Mazda6 has not been released yet. All specifications will be released closer to the model’s arrival at dealerships.
