General Motors vs. Tesla: What Revenue Growth Trends Tell Investors About These Automotive Giants

TSLA is growing revenue 26% year over year while GM manages just 2%, according to Q2 2026 figures that show a widening momentum gap between the two automakers.

GM still holds the scale advantage: $48B in Q2 2026 revenue versus $28.2B for TSLA. That gives GM roughly 70% more top-line revenue, yet it is expanding at a fraction of TSLA's pace.

The EV picture explains much of the divergence. GM's EV sales fell 43%, leaving the company leaning on hybrid and gas-powered vehicles alongside its AI initiatives. TSLA, by contrast, continues to hold EV dominance even though federal tax credits have expired, which suggests its demand is not dependent on that subsidy.

Interpretation: the numbers frame a classic scale-versus-growth tradeoff. GM's 2% growth on a $48B base signals a mature, defensive profile, while TSLA's 26% growth on a smaller base shows it compounding faster. A 43% EV sales drop at GM is a sharp contraction that makes its reliance on non-EV segments the central question for its revenue trajectory.

No MMM data appears in this comparison, so the read-through here is strictly GM versus TSLA.
