Yahoo Autos The 2019 Nissan Altima's New VC-Turbo Engine Delivers on MPG
Nissan is offering an advanced new turbocharged engine in the new 2019 Altima mid-size sedan, and we now have the official fuel-economy numbers for it. The VC-Turbo 2.0-liter four-cylinder, which is optional on the Altima, incorporates the same variable-compression-ratio tech first introduced in the Infiniti QX50 luxury crossover. SR, Platinum, and Edition One versions of the Altima with the 248-hp VC-Turbo, all of which pair with front-wheel drive and a continuously variable automatic transmission (CVT), are EPA rated at 29 mpg combined, 25 mpg city, and 34 mpg highway.
The VC-Turbo four-cylinder's numbers are an improvement over those of the 3.5-liter V-6 it replaces. They also top the fuel-economy figures for other comparable mid-size sedans' upgrade engines, which are a mix of turbo fours and V-6s. Looking at combined fuel-economy numbers, the 2019 Altima's 29 mpg beats the old Altima V-6, the Toyota Camry V-6, and the Mazda 6 2.5T, all by 3 mpg. The Honda Accord with its turbocharged 2.0-liter four-cylinder comes closest to the new Altima, at 27 mpg. The Accord matches the Altima's highway estimate, at 34 mpg, but the others fall a few mpg short using that metric.
As always, your mileage may vary in the real world. So we are eager to test the 2019 Altima's VC-Turbo on C/D's75-mph highway fuel-economy loop, where we have achieved 35 mpg in an Accord 2.0T, 29 mpg in a Camry V-6, and 36 mpg in a Mazda 6 with its turbo engine.
The 2019 Altima's base engine, a revised 2.5-liter naturally aspirated four-cylinder with 188 horsepower, records a less significant improvement over the old car. It improves by about 1 mpg across the board, with the front-wheel-drive S, SV, and SL models earning ratings of 32 mpg combined, 28 mpg city, and 39 mpg highway (the SR and Platinum trims are rated a bit lower). All-wheel drive is newly available for the 2.5-liter models, and it drops the numbers by 2 to 3 mpg, according to the EPA.
