Earlier in the year, BMW announced that the future of their 5-Series would be all turbo. No longer in production is a naturally aspirated middle child as the 3.0 liter straight six has officially been replaced. Now under the hood of all base 5-Series is the company’s all-new turbocharged four cylinder. To accompany the gas burning four is a new turbocharged diesel inline four cylinder that will be found on the next 520d and 525d.
Behind the 520i and 528i badge is a turbocharged, direct injected, Double-Vanos 2.0 liter inline four. In 520i trim, 184 horsepower and 199 lb-ft of torque is produced so that 62 mph will be achieved in 7.9 seconds with the six speed manual. For the 528i, boost pressure is raised and different fuel injectors are used so the same engine can produce 245 horsepower and 258 lb-ft. With the six speed manual, 62 mph will be hit in 6.2 seconds. What might be more impressive than the new four’s output and acceleration are its fuel economy ratings. Around 40 mpg can be averaged on both cars, including the high output 528i. Both the 520i and 528i can be fitted with the newly built, ZF eight speed automatic.
The new 520d Efficient Dynamics Edition will also hit BMW showrooms soon. 184 horsepower and 280 lb-ft of torque form an all aluminum 2.0 liter twin turbocharged diesel four cylinder accompany a six speed manual to that 62 mph can happen in 8.2 seconds. Accompany the low-end grunt of the new engine is the ability to average 62.8 mpg.
