The BMW i3 electric car enters its second model year largely unchanged, with a few added features and a price hike to boot.

The 2015 BMW i3 now comes standard with DC fast-charging capability, satellite radio, and heated front seats--for a starting price that's $1,075  higher than the 2014 model.

Prices start at $42,400 for a base i3, compared to $41,350 for 2014. BMW also raised the destination charge $25--to $950--for a total price of $43,350.

The price increase also applies to the range-extended i3 REx model, which starts at $47,200--compared to $46,125 for the 2014 model.

There are no mechanical changes, meaning all i3 models still use an electric motor with 170 horsepower and 184 pound-feet of torque, powered by a 22-kilowatt-hour lithium-ion battery pack.

The i3 REx adds a 34-hp, 650-cc two-cylinder gasoline engine boosting range to 150 miles, compared 81 miles for the electric-only version.

That version is rated at 124 MPGe combined, which is the highest efficiency rating of any vehicle--gasoline, diesel, hybrid, or all-electric--currently sold in the U.S.

Meanwhile, the range-extended i3 REx is rated at 117 MPGe, or 39 mpg combined when running on gasoline power.

DC fast charging was a $700 option on 2014 models, and uses the Combined Charging Standard (CCS) protocol.

Discussing then-unconfirmed 2015-model-year updates last fall, executives said there are now enough CCS public charging stations to justify making the feature standard.

The change comes as BMW--along with fellow CCS adherent Volkswagen and network operator ChargePoint--embarks on a project to expand the CCS infrastructure.

The companies will partner to build 100 fast-charging sites along heavily-traveled corridors on the East and West Coasts this year. Construction of the first site is already underway in San Diego.
