VW expects the all-new Jetta to be more frugal on
fuel, once it arrives in dealers across the US this summer. Despite being
larger than the current model the 2019 Jetta makes use of clever and affordable
technologies in order to improve its fuel economy, with VW announcing an
EPA-estimated 30mpg city/40mpg highway/34mpg combined, two mpg higher on the
combined than the current automatic model.
VW has optimized the exterior of the new Jetta for
aerodynamic drag reduction while also added shutters in the front grille that
close in certain speeds and when the engine requires less air flow. The company
has also designed the front bumper with an “air curtain” feature that lowers
turbulence over the wheels.
The underbody panels are sculpted to
ensure that suspension components will not create unnecessary air obstructions
while the styling of the rear end helps smooth the air flow. The result of
these measures is a class-leading drag coefficient of 0.27.
The new 2019 VW Jetta is powered by the 1.4-liter
TSI petrol engine, which has been further optimized to sip less fuel. Features
like a clutch-driven air-conditioner, a more efficient generator and a
smoother-flowing grade of oil contribute the to improvement of the engine’s
fuel efficiency.
All 2019 Jettas with an automatic transmission will
be fitted with a start-stop function as standard, with VW claiming a reduction
of fuel consumption by as much as 6 percent. The new eight-speed automatic
transmission also helps, as well as a set of low-resistance tires that reduce
resistance by up to 25 percent, without sacrificing handling, always according
to VW.
