2027 Kia Seltos vs 2026 Mazda CX-30: Denver Comparison

Price and Value: Seltos vs CX-30

The all-new 2027 Kia Seltos starts at $24,990, while the 2026 Mazda CX-30 begins at $26,375. That means the fully redesigned Seltos actually undercuts the CX-30 by nearly $1,400, and the real value gap grows even wider when you factor in what each vehicle includes at that price point and over the long haul.

The second-generation Seltos pairs its competitive MSRP with Kia's industry-leading warranty package, which covers the powertrain for 10 years or 100,000 miles. When you factor in that coverage against the CX-30's 3-year/36,000-mile basic warranty, the Seltos delivers substantially more peace of mind per dollar spent. For Denver buyers financing a compact SUV, that extended protection can save thousands in potential repair costs over the ownership period.

Engine and Performance

The Seltos offers two engine options. The standard 2.0-liter four-cylinder produces 147 horsepower, while the available 1.6-liter turbocharged engine delivers up to 190 horsepower. Front-wheel drive comes standard, with all-wheel drive available across the lineup.

The CX-30 starts stronger with a 2.5-liter four-cylinder making 191 horsepower as the base engine. An available 2.5-liter turbo pushes output to 250 horsepower, and AWD is standard on every trim. That standard AWD is a real advantage for Denver winters, though the Seltos AWD option keeps it competitive for drivers who want that capability.

If raw power is the priority, the CX-30 has the edge. But the Seltos turbo delivers strong performance for most driving situations while keeping costs and fuel consumption lower.

Fuel Economy Comparison

The Seltos takes a clear lead in fuel efficiency, which matters on long Colorado highway drives and daily Denver commutes alike.

The Seltos 2.0L with FWD achieves 28 city / 33 highway / 30 combined MPG. With AWD, it still manages 26/30/28. The turbocharged Seltos with AWD returns 24/30/26 MPG.

The CX-30 base engine manages 24 city / 31 highway / 27 combined MPG, and the turbo drops to 22/30/25. Across every configuration, the Seltos uses less fuel than its Mazda counterpart. Over five years of average driving, that difference adds up to hundreds of dollars in gas savings.

Interior and Cargo Space

This is where the Seltos pulls away decisively. Behind the rear seats, the Seltos provides 27.8 cubic feet of cargo space compared to the CX-30's 20.2 cubic feet. That is nearly 38% more room for groceries, luggage, or gear for a weekend trip to the mountains.

Fold the rear seats flat and the gap widens further: 64.2 cubic feet in the Seltos versus 45.2 in the CX-30. Whether you are hauling ski equipment up I-70 or loading up at a Denver Costco, the Seltos gives you meaningfully more flexibility without stepping up to a larger, more expensive SUV.

Both vehicles offer comfortable seating for five passengers, modern interior materials, and intuitive infotainment systems. The CX-30 leans into a more premium cabin feel with its design and material choices, while the Seltos prioritizes practicality and usable space.

Safety and Technology

Both the Seltos and CX-30 come well equipped with advanced driver-assistance features. The CX-30 has earned an IIHS Top Safety Pick+ rating, the highest designation from the Insurance Institute for Highway Safety.

The fully redesigned Seltos includes a comprehensive suite of standard safety technology across its trim levels, including forward collision avoidance, lane keeping assist, and driver attention warning systems. Higher trims add blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, and an available Surround View Monitor.

For technology, both vehicles offer touchscreen infotainment with smartphone integration. The 2027 Seltos features a 12.3-inch touchscreen paired with a 12.3-inch digital instrument cluster and a dedicated 5-inch climate display — a significant upgrade over the previous generation's dual 10.25-inch setup. Wireless Apple CarPlay and Android Auto come standard.

Warranty and Long-Term Ownership

The warranty comparison is not close. Kia's coverage package is one of the most generous in the industry:

• Kia Seltos: 5-year/60,000-mile basic warranty, 10-year/100,000-mile powertrain warranty
• Mazda CX-30: 3-year/36,000-mile basic warranty, 5-year/60,000-mile powertrain warranty

That means the Seltos powertrain is covered for twice as long and nearly twice the mileage compared to the CX-30. For Denver drivers who plan to keep their vehicle for several years or put on significant miles commuting along the Front Range, this warranty difference translates directly into long-term savings and reduced ownership risk.
