A Range Rover taking on the Empty Quarter in record time.
2016 4WD Range Rover and Sport Td6 – Pricing TBA while offering owners an unusually high for the brand, 22/28 mpgUS city/highway rating.
Detroit, Michigan – At the 2015 North American International Auto Show (NAIAS), Land Rover had two very interesting additions to its U.S. lineup. Following up on the 2016 Jaguar XE TD announcement, Land Rover revealed it was also playing the diesel card for the two key upcoming 2016 model year releases. The company also stated it will make its in-house designed, LEV3 emissions certified turbo diesels available across entire Land Rover lineup in coming years.
This fall Land Rover will offer consumers the option of a fuel efficient diesel powertrain in two 2016 model year luxury SUVs, the Range Rover and Range Rover Sport. Using an all-new 3.0L V6 turbo diesel with the moniker Td6, the two SUVs will provide owners with a 22/28/25 mpgUS city/highway/combined rating, a 32 percent improvement over the supercharged V6 currently available.
The 3.0L V6 Td6 turbo diesel engine is rated at 254 hp and 440 lb-ft. This high torque output at low RPM makes the diesel Range Rover and Range Rover Sport models particularly easy to drive and provides huge benefits off-road were maximum torque at low RPM is extremely beneficial. The powerful new TDs will launch the Range Rover Sport Td6 and Range Rover Td6 to 60 mph in 7.1 and 7.4 seconds respectively, an unnoticeable 0.2 and 0.3 seconds off the V6 gas engines.
As part of a complete model redesign for the 2013 and 2014 model years, the Range Rover and Range Rover Sport have moved to all-aluminum platforms and have had significant interior/exterior/chassis design changes in an effort to continuously improve the brands offerings.
The Td6s block is constructed of NVH reducing and stronger Compacted Graphite Iron (CGI). Its overall advantages in weight and strength mean the block can be lighter and smaller. The deep-skirted, cross-bolted design and one-piece structural aluminum oil sump of the Td6 help the engine to absorb combustion noise which improves driver isolation.
To meet the upcoming Tier III emissions control regs, Land Rover is using a std. Selective Catalytic Reduction (SCR) system with Diesel Exhaust Fluid (DEF) as the reductant to reduce NOx.
The reservoir for the DEF is located under the floor with the secondary located under the hood. Combined they hold enough fluid for approximately 10,000 miles. DEF is commercially available and owners can top the fluid level up themselves or take it to their nearest Land Rover dealer if the reservoir needs replenishing.
A new Low Pressure EGR system further improves fuel economy. Unlike traditional High Pressure EGR systems, which recirculate gases directly from the exhaust manifold to inlet manifold at high pressure, the revised design takes gases at low pressure - after the Diesel Particulate Filter (DPF) filter - and feeds them back to the turbocharger inlet. From here they pass through an intercooler, resulting in a lower peak combustion temperature.
A new two-stage oil pump reduces engine losses while a revised design for the fuel-injectors improves efficiency and reduces hydrocarbon emissions. Like all late model TDs, the Land Rover Td6 uses multiple injection cycles to reduce NVH and emissions while providing improved economy and power.
Dual-isolation engine mounts, acoustic laminate windshields and an isolating engine bay to cabin firewall help reduce noise levels further.
The fuel filler neck on diesel Land Rover vehicles is fitted with a misfueling protection device. This device will prevent the narrower gasoline fuel nozzle fitted to gasoline pumps from being inserted into the filler neck on the vehicle, reducing the likelihood of adding the wrong fuel.
The Consumer
Early on in the development process, Land Rover conducted clinics with premium SUV buyers to determine whether customers would notice a difference between the turbo diesel and gasoline models.
Without informing participants that they'd be driving the turbo diesel, feedback using in-vehicle video and audio recordings, data loggers and post-drive interviews showed consumers could not identify if they were driving a diesel vehicle during a 30-minute test drive.
By the time US sales begin this fall, the Td6 prototype fleet will have logged over one million test miles.
