Revised rules that went into effect on January 1 took away federal tax credits on all but about a dozen EVs. But General Motors will make up for that loss by offering up to $7,500 in discounts on EVs like the Cadillac Lyriq and Chevrolet Blazer EV, the automaker said. Ford, meanwhile, said it is raising the price on some versions of its F-150 Lightning by up to $10,000, while lowering the cost of premium models by as much as $7,000.
