Every weekday, we bring you the Ad Age/iSpot Hot Spots, new and trending TV commercials tracked by iSpot.tv, a company that catalogs, tags and measures activity around TV ads in real time. The New Releases here ran on TV for the first time yesterday. The Most Engaging ads are showing sustained social heat, ranked by SpotShare scores reflecting the percent of digital activity associated with each one over the past week. See the methodology here.

Among the new releases, a commercial for General Electric Software tells a story of two fuel gauges: one that doesn't save fuel and one that does, allowing for additional flights. Meanwhile, the 2015 Can-Am Spyder lineup has arrived, and the brand is urging consumers to "experience the complete freedom and confidence" the vehicle has to offer.

A spot for the Microsoft Surface 3 tablet makes class look like a blast. The gadget, a budget-friendly tablet and laptop combo, allows youngsters to zoom in and out on plant cell diagrams, take notes in algebra class and check out other sites -- definitely not Facebook or Twitter -- that help them focus on learning.
