Next Corvette ZR1 to get 700 horsepower?

Word has it General Motors may offer as much as 700 horsepower in the C7 Corvette ZR1. Motor Trend reports the next Corvette Z06 will continue to rely on its naturally aspirated 7.0-liter V8 engine for thrust, but the lump will deliver substantially more power. How much more? MT says the engine could deliver up to 600 ponies. That's a jump of 95 horsepower over the current Z06, though no figures have been finalized as of yet. Right now, GM is reportedly waiting to see what sort of grunt it can glean from the next ZR1.
The automaker has already made it clear it will resurrect the LT5 name for the new supercharged V8, and if GM is already pulling 600 from the Z06, the big dog ZR1 would theoretically offer 700 horsepower. Either way, the range-topping Corvette will be suitably insulated from its less potent siblings. Stay tuned. We aren't likely to see the Z06 for at least a year, with the ZR1 trailing along at some point there after.

Chevy Colorado and GMC Canyon get trim levels reworked again

GM Authority reports that GM has fiddled with trim packages on the Chevrolet Colorado and GMC Canyon for the 2021 model year, eliminating the base trims on both pickups and implementing small price changes. When the new model year goes on sale, the Chevy will lose the rear-wheel drive Base Extended Cab with the automatic transmission that starts at $22,395 after a $1,095 destination charge. The new entry-level is going to be the Work Truck model with the extended cab in rear-wheel drive, starting at $26,595 assuming the destination charge holds steady. That represents a $4,200 jump over the base 2020 model. MSRPs for the entire Work Truck lineup, from base to the Crew Cab Long Box, rise by $400. Elsewhere in the Colorado line, the four Z71 trims go down by $100, while the two ZR2 trims increase by the same amount. Only the six LT trims don't see any change.  The GMC side is a bit more involved due to previously announced changes. The 2020 Canyon comes in SL, Base Canyon, SLE, SLT, All Terrain, and Denali steps. Last month, GM Authority reported the 2021 Canyon would give all that up for the new names Elevation Standard, Elevation, AT4, and Denali. Since the SL base model retires in 2021, the Elevation Standard takes over at the entry level. Unlike on the Colorado, which sheds one trim, the Canyon lineup gets pared from 20 total combinations of trims, cab sizes, and bed lengths, to 14 total combinations. But like the Colorado, due to the loss of the cheapest configuration, the least expensive 2021 Canyon becomes $4,200 more expensive than in 2020, assuming the destination price remains the same. What's more, the 2021 Elevation Standard pricing adds $700 or $800 to the prices of the 2020 Canyon base and SLE models. There are more increases up the range. The 2021 Elevation trim replaces a combination of SLE and SLT models, bumping prices up by up to $900. In 2020, the least expensive All Terrain model is the Extended Cab Cloth for $37,695. For next year, the least expensive AT4 trim is the Crew Cab Short Box for $39,295. Like-for-like, though, the AT4 represents a $300 premium over the 2020 All Terrain Crew Cab Short Box. Three Denali trims will still stand at the top of the heap, each one going up by $400 in 2021. Until GM details the equipment changes, we won't know how the new pricing equates to value.

GM Canada recalls 159,240 GMC and Chevy trucks for faulty defroster circuit

General Motors is recalling more than 159,000 2014-2019 Chevrolet Silverado and GMC Sierra pickup trucks in Canada due to a potential fire risk. GM says the rear defroster circuit could overheat on trucks optioned with the power-sliding rear window. Thus far, there is no word on the recall's relation to U.S. vehicles. The recall, found by Automotive News, was posted to Transport Canada on June 28, 2019 with manufacturer recall No. N192220470. Included in the 159,240 vehicles are the 2014-2018 Silverado 1500, the 2015-2019 Silverado HD, the 2014-2018 Silverado LD, the 2014-2018 Sierra 1500, the 2015-2019 Sierra HD, and the 2014-2018 Sierra LD. The notice says the rear defroster circuit, specifically on trucks with the power-sliding rear window, could overheat. Because of its placement, this excess heat could cause melting, smoking, or possibly fire, in the worst case scenario. As of now, there is no official word when GM will initiate the recall and there is no official fix detailed just yet. GM suggests that owners, who will be notified by mail if their vehicles are affected, take their trucks to a dealer to remove the rear window defroster fuse as a stop-gap.  Automotive News contacted GM to find out if the problem is also found in trucks sold in the United States, but no definitive statement was made, as the investigation is reportedly ongoing. We will update this space if American vehicles are found to be included in the problem.
