Investor, Kirk Kerkorian, has been pressuring GM to sell off Hummer but executives argued that it was one of GM’s core brands. Currently, sales of Hummer are up almost 50 percent for the first 8 months of this year compared to the rest of GM, which is down 12 percent overall. Hummer’s smallest model, the H3, accounts for three-quarters of the brand's current sales. GM executives already realise that a smaller Jeep Wrangler sized model would be the ideal option.
