"The new Spark's design has evolved and grown up with the segment," said Michael Simcoe, GM international vice president of design, in a statement on Monday. "The youthful whimsy of the original Spark is still in its genes, but it is conveyed in more traditional proportions that reinforce the customer's refined expectations."
A single teaser photo of the 2016 Spark shows a radically revised rear end and a more conventional roof line than the current model.
The design of the 2015 Spark has been described as edgy and even somewhat cartoonish.
GM says the changes to the Spark include a "more aerodynamic profile" that conveys a "more sophisticated aesthetic."
The Spark is a key vehicle in the Chevrolet portfolio, since it is designed to attract younger and first-time buyers and keep them loyal to the brand as they grow up.
Pricing and technical specifications on the 2016 Spark have not been announced.
Chevrolet spokeswoman Afaf Farah told Edmunds the automaker is not confirming an on-sale date at this point.
Edmunds says: The redesigned 2016 Spark is aimed at the millennial customers that GM wants to lure into showrooms. Their reaction to the unveiling will be closely watched in the Big Apple.
