2018 Buick LaCrosse switches to hybrid as standard and drops entry price
Buick's 2018 LaCrosse introduces a mild hybrid 2.5-litre as the new base engine, replacing the V6 and reducing the starting price by $2,500 in the US.
Buick has updated its LaCrosse saloon for 2018 by introducing a new standard mild hybrid powertrain on the base model. The new setup pairs a 2.5-litre four-cylinder petrol engine with an eAssist mild hybrid system, which includes a motor generator unit and a 0.45 kWh lithium-ion battery. This replaces the previous V6 as the entry-level engine.
Hybrid Powertrain Now Standard
The eAssist system takes the place of a traditional alternator, enabling regenerative braking to recharge the battery and providing extra torque during initial acceleration. Stop/start technology is included as standard, helping to further reduce fuel consumption in city driving. Active grille shutters in the upper and lower front grilles are also fitted to improve aerodynamic efficiency.
Lower Entry Price
With the introduction of the hybrid powertrain, Buick has reduced the starting price of the LaCrosse to $30,490 in the US. This is $2,500 less than the previous base model, which was equipped with a 3.6-litre V6 engine and started at $32,990. The more affordable price point is likely to appeal to buyers looking for a combination of efficiency and value in a large saloon.
Efficiency Improvements
Buick states that the new hybrid system should deliver a 19 percent improvement in city fuel economy compared to the outgoing V6 base model. The mild hybrid’s regenerative braking system helps maintain battery charge, while the electric motor assists with acceleration from a standstill. Although Buick has not yet released full power and performance figures for the hybrid model, the focus is clearly on efficiency gains for urban driving.
V6 Engine and Additional Options
For those who prefer more power, the 3.6-litre V6 engine remains available on higher trim levels. This engine is now matched with a nine-speed automatic transmission, which is intended to enhance both performance and fuel economy. Additionally, all-wheel drive can be specified for the Essense trim, making the LaCrosse a more versatile option in regions where winter weather and slippery roads are a concern.
New Exterior Colours
The 2018 LaCrosse also introduces three new exterior paint choices: Satin Steel Metallic, Dark Slate Metallic, and Red Quartz Tintcoat. These options provide buyers with more ways to personalise their vehicle and keep the model looking fresh against competitors.
Comparison: Hybrid vs V6 Base Model
| Feature | 2018 Hybrid Base | Previous V6 Base |
|---|---|---|
| Engine | 2.5-litre 4-cylinder + eAssist | 3.6-litre V6 |
| Hybrid System | Standard (mild hybrid) | Not available |
| Starting Price (US) | $30,490 | $32,990 |
| Fuel Economy (City) | 19% improvement (claimed) | Baseline |

| All-Wheel Drive | Not on base | Not on base |
Market Position and Outlook
The move to a standard mild hybrid system and a lower starting price positions the 2018 Buick LaCrosse to better compete with rivals offering electrified powertrains. The efficiency improvements and additional features are designed to attract buyers who are increasingly considering hybrid technology in their next vehicle. While detailed performance data is still to come, the changes indicate Buick’s intention to keep the LaCrosse relevant in a segment where efficiency and value are becoming more important to consumers.
