GM's 2027 Midsize Trucks Gain 350 HP, Trailing Only Ford Raptor

Key points

• GM's new 2.7L 'L4B' TurboMax engine produces 350 hp at 5,200 rpm and 455 lb-ft of torque at 3,000 rpm.
• The 2027 Colorado and Canyon will be the most powerful midsize trucks, excluding the Ford Ranger Raptor's 405 hp V6.
• The L4B engine replaces the outgoing L3B unit, featuring improved turbocharger and thermal systems for better noise and vibration control.
• The Toyota Tacoma Hybrid produces 465 lb-ft of torque, exceeding the L4B's torque output, but the L4B leads in horsepower.
• GM confirmed the L4B engine for midsize trucks via its fleet order guide, following its announcement for full-size Silverado and Sierra models.

Background

GM has been expanding its engine lineup across segments, recently introducing new V8s for full-size trucks. The midsize segment has seen increased competition from hybrids, such as the Toyota Tacoma, which offers higher torque but lower horsepower. Previous comparisons showed the Chevy Colorado had lower running costs than the Tesla Cybertruck but higher upfront costs than some rivals.

How outlets are covering it

The Fast Lane Truck emphasizes the L4B engine's class-leading horsepower and its transfer from full-size to midsize trucks. CNBC highlights GM's broader strategy to counter Ford and Stellantis in the full-size segment, noting that midsize updates are part of a larger push to maintain sales leadership. Road & Track focuses on the technical reliability of GM's new V8 engines, while The Drive criticizes GM's decision to remove physical oil dipsticks in favor of digital gauges, a trend that may also affect midsize models. The outlets agree on the L4B's power figures but differ in focus: TFLtruck on midsize performance, CNBC on market strategy, and The Drive on consumer convenience.

Why it matters

The L4B engine's adoption in midsize trucks signals GM's intent to compete on performance rather than just efficiency. With the Ford Ranger Raptor remaining the only more powerful option, GM aims to attract buyers seeking power without the premium price of high-performance variants. This move could shift market dynamics as hybrids like the Tacoma offer torque but less horsepower, making the L4B a key selling point for traditional truck buyers.

What to watch

GM will likely announce pricing and availability for the 2027 Colorado and Canyon in the coming months. The company may also address consumer concerns about digital oil gauges if they extend to midsize models. Competitors like Ford and Toyota may respond with further updates to their midsize lines to maintain market share.
