MG has begun placing production-spec MG 07 cars in Chinese showrooms ahead of preorders, revealing a fastback sedan that combines semi-solid battery options, LiDAR, an 800-volt platform, and ambitious range claims in a surprisingly low price band. <\/p>\n\n\n\n

The company says a LiDAR-equipped model with 379 miles of CLTC range will stay below roughly $22,100, while the 522-mile flagship is intended to cost less than about $26,500. These are announced targets rather than final export prices.<\/p>\n\n\n\n

MG is testing whether technology once associated with premium electric cars can be sold to mainstream buyers, although the fine print matters because the semi-solid pack<\/a> belongs to lower-voltage versions and the headline range is measured on China\u2019s CLTC laboratory cycle.<\/p>\n\n\n\n

A family sized electric fastback<\/h2>\n\n\n\n

The MG 07 has a five-door fastback body with a long roofline, a lift-up rear hatch, frameless doors, and an adjustable rear spoiler. It measures about 16 feet long, 74.8 inches wide, and 58.2 inches tall, with a 111.2-inch wheelbase that should leave useful room for five passengers.<\/p>\n\n\n\n

The lower-cost electric versions use a 400-volt architecture, a rear motor producing about 236 horsepower, and a reported 67-kWh semi-solid battery. Chinese regulatory information lists two CLTC ranges for this setup, roughly 379 and 404 miles, giving MG room to offer both a cheaper entry model and a longer-range alternative.<\/p>\n\n\n\n

Above them sits an 800-volt version<\/a> with a CATL ternary lithium battery and up to 320 horsepower. MG advertises a 0-to-62-mph time of about six seconds and a maximum range of roughly 522 miles under CLTC testing.<\/p>\n\n\n\n

MG introduces the MG 07 fastback sedan in China, featuring semi-solid-state battery options and up to 840 km of range.<\/figcaption><\/figure>\n\n\n\n

Semi-solid does not mean fully solid<\/h2>\n\n\n\n

The phrase \u201csemi-solid-state battery<\/a>\u201d can sound more revolutionary than it is. Unlike an all-solid-state cell<\/a>, it still contains a gel-like or partly liquid electrolyte, placing it between conventional lithium-ion chemistry and the fully solid batteries that researchers and automakers are still working to commercialize.<\/p>\n\n\n\n

That does not make the technology unimportant. Its real significance is that SAIC is trying to manufacture this intermediate design at scale and put it in a relatively affordable sedan. Still, buyers will need independent evidence on degradation, cold-weather performance, repair costs, and crash safety.<\/p>\n\n\n\n

The range headline needs context<\/h2>\n\n\n\n

The 522-mile figure is a laboratory result from the China Light-Duty Vehicle Test Cycle, usually shortened to CLTC, not an EPA rating and not a promise that the car will cover that distance at U.S. highway speeds with the air conditioning or cabin heater running.<\/p>\n\n\n\n

MG\u2019s own Chinese material currently varies slightly, with one page advertising 845 kilometers and a detailed media section listing 840 kilometers. Converted into U.S. units, that is a narrow spread of about 522 to 525 miles, but the more important missing number is a standardized result from another market.<\/p>\n\n\n\n

The 67-kWh version deserves just as much attention. Claiming as much as 404 CLTC miles from a moderate-size pack suggests that efficiency, aerodynamics, and a generous test cycle are all doing part of the work. Real-world energy consumption will show how much of that promise survives daily driving.<\/p>\n\n\n\n

Fast charging needs more than one number<\/h2>\n\n\n\n

The top MG 07 supports an 800-volt electrical system and a claimed 5C charging rate. In simple terms, 5C signals an extremely high theoretical charging rate, but it does not tell drivers the peak power, the time needed to charge from 10 to 80%, or how long the battery can hold that speed before tapering.<\/p>\n\n\n\n

MG has not yet published all of those practical charging details. That matters because a road-trip stop is shaped by the charger, battery temperature, charging curve, and software, not just the number printed in a brochure.<\/p>\n\n\n\n
