Mazda 6 engines
Mazda 6 is a mid-size Japanese car from Mazda Motor Corporation. In the Japanese and Chinese markets, the car is sold under the name Mazda Atenza. The year of the start of car production is 2002. 3 generations of Mazda 6 were manufactured. The 1st generation is still manufactured in China. The model has a characteristic set of body types for a car of its class – sedan, station wagon and hatchback.
Mazda 6, 1st generation, 2002–2008
In the Russian market, Mazda 6 was offered with petrol engines 1.8 (120 hp), 2.0 (141 hp) and 2.3 with 166 hp. Gearboxes – five-speed manual transmission or four-speed automatic transmission. In Europe, there were also versions with a two-liter turbodiesel developing 120, 136 or 143 hp, depending on the modification, and in North America, a Mazda 6 with a three-liter V6 engine (218 hp) was also offered.
Restyling in 2005 practically did not affect the appearance of the car, but the interior trim was improved. The two-liter power unit received a variable valve timing system and became a little more powerful – 147 hp. The manual transmission has become a six-speed (on versions 2.0 and 2.3), and the automatic has a five-speed. Later, deliveries of station wagons with a 2.3-liter engine and all-wheel drive began.
A special place in the model range was occupied by the “charged” sedan Mazda 6 MPS (in the USA it was called Mazdaspeed 6) of the 2004 model. It was equipped with a turbocharged 2.3-liter engine with direct fuel injection, which developed 260 hp, an all-wheel drive system and a manual transmission.
In Japan, the production of cars ended in 2008, but in China this model is still produced by the FAW-Mazda joint venture. Cars for the local market are equipped with two-liter engines with a capacity of 145 hp.
Mazda 6, 2nd generation, 2008–2012
Mazda 6 was equipped with four-cylinder petrol engines 1.8 (120 hp), 2.0 (147 hp) and 2.5 with 170 hp. In Europe, versions with two-liter turbodiesels (140 hp) or 2.2 liters (125–185 hp) were also offered. A six-speed automatic transmission was offered as an option for cars with 2.0 and 2.5 petrol engines.
In the American market, only a sedan was available, and it differed from the European car by a wheelbase extended by 6 cm. This Mazda 6 was offered with a 2.5 engine, as well as a 3.7-liter V6 with 276 hp.
In 2010, the two-liter gasoline engine was upgraded and received direct fuel injection, and its output increased to 155 hp. In the same year, the Mazda 6 received a slightly updated design.
