Mazda Inline-Six 3.3 liter diesel engine detailed, makes 406 LB-FT
Rumors of a rear-wheel-drive platform with inline-six engines from Mazda have been circulating for years, but the official announcement was only recently made. After unveiling plans to launch RWD vehicles with 3.0-liter gasoline and 3.3-liter diesel powertrains, Zoom-Zoom is finally ready to talk specs. However, for now, we will have to settle for those of the oil burner.
Without further ado, the standard SKYACTIV-D 3.3 develops 228 horsepower (170 kilowatts) between 4,000 rpm and 4,200 rpm. The full amount of torque, 500 Newton-meters (369 lb-ft), is accessible from 1,500 rpm all the way up to 3,000 rpm. Then there’s an e-SKYACTIV D variant of the same diesel engine, but with an integrated mild-hybrid setup. It increases power to 251 hp (187 kW) at 3,750 rpm while torque rises to 550 Nm (406 lb-ft) from 1,500 rpm to 2,400 rpm.
The straight-six diesel works with an eight-speed automatic transmission that sends power to both axles of the new CX-60 SUV that weighs around 1,900 kilograms (4,189 pounds). The diesel SUV will do 0 to 62 mph (100 km/h) in 7.3 seconds before reaching a top speed of 137 mph (220 km/h).
Tech specs for the 3.0-litre petrol engine weren’t provided, but at least we can compare the diesel with the already-revealed 2.5-litre plug-in hybrid model. It combines a naturally aspirated four-cylinder petrol mill with an electric motor for a total output of 323 hp (241 kW) at 6,000 rpm and 500 Nm (369 lb-ft) at 4,000 rpm.
As expected, the CX-60 PHEV version weighs considerably more due to the additional hardware, at around 2,050 kg (4,519 lb). Despite carrying an extra 150 kg (331 lb), the petrol-electric SUV does the sprint in 5.8 seconds or 1.5s faster than the diesel thanks to its electric boost. At full throttle, it reaches 124 mph (200 km/h).
Fun fact – the PHEV model has a perfect 50:50 weight distribution while the diesel is slightly nose-heavy, at 55:45. The plug-in hybrid model with its electric motor is also an all-wheel-drive affair with an eight-speed automatic transmission and comes. It has a 17.8 kWh battery for an electric range of up to 39 miles (63 km) in the WLTP combined cycle.
As you’ve probably heard, the global CX-60 will be sold in the United States as the widebody CX-70. Mazda is also planning a three-row CX-80 for international markets, joined by a CX-90 for the United States. They will all arrive within the next two years.
